Modern day businesses have to be ready to embrace technology in order to be successful in this day and age. If you are starting up a new business, then one of the biggest considerations that you are going to want to make has to do with how you intend to use technology like the Internet or Metrofax Internet Faxing to benefit your business. If you do not already have a website presence of some kind, now is the time for you to consider putting your new business on the map by putting it on the Web.

If you own a business, then you are going to want to have a web presence of some kind. If you sell products, services or information online, then having good online customer service is going to be essential. Being able to provide good customer service to each and every one of your customers is vitally essential in order for your business to build a strong positive reputation. You are also going to want to rely on customer feedback as well as adaptation, especially in the early stages of your business. A new business is going to benefit significantly from receiving customer feedback, because the information that you receive from your customers is vital feedback that you can apply to your future business practices.

The Internet provides an excellent forum for you to receive feedback from your customers. Not only will you be able to receive feedback through your own web presence, but through sites like Yelp and Merchant Circle as well. Customers can come to these websites and voice their opinions about their experiences with you so that others can read them. You can absolutely benefit from these reviews as well. Promote these review sites and ask your customers to leave feedback about your business so that you can grow and evolve your company accordingly.

Computers safety may have existed before the internet became popular. Today, any and every device connected to the internet is at risk. Does this mean that you can restore computer safety by simply disconnecting it from the internet? Well, this option may have been useful in the past but is no longer of any use today.

Nowadays, it is possible to reverse engineer a chip to understand its security features. Once done, hackers can come up with cracks that will bypass the inherent security of computer chips. Remember, the chip happens to be the heart of your computer. The software application that is installed in your operating system running on your hard disk merely happen to be the exterior façade. If the chip is compromised, you can be rest assured that every bit of data in your computer can be stolen without anybody knowing about it.

This is not as easy as it sounds but is not impossible either. A person who is prepared to invest time and effort in this task can easily crack the safest computer chip. In fact, experts have admitted on the internet that it is almost impossible to create an infallible computer chip. Military agencies often insist on domestic manufacture of chips because they don’t want foreign governments snooping in on their data accessed through the compromised chip.

The point here is that one should never take computer security for granted. All it takes is a single flaw or a single crack for the hacker to gain access to your system. It is advisable to adopt a curative approach even as you try to prevent such problems from occurring.

First important step is to use safe, well-known, and reputed security software applications as well as firewall. It is very important to avoid fake applications. Though there are many free security software available in the market, it is quite safe to go for paid versions. The software should be updated and latest patches should be incorporated.

While sharing email ids with any website, the user should be very careful and analyze the website very well to avoid spam mails. It is very important to read the privacy statement of the website before sharing the email id.

The password should be very strong and it should be the combination of characters, numbers, and strings. It is a bad idea to keep name, birth date, or any personal information as the password because the hackers can easily trace such passwords through social engineering.

Downloading should be done very carefully and pirated stuff should be avoided. This is not only illegal, but also this is a source of many virus that could possibly attack PC. The Internet users should not click anything other than their work because this could be the source of hackers or malware.

It is not surprising that humans rely on cluster computing to carry out complicated activities on computers without investing a lot of money for excess computing power. The brain is the best example of a cluster computer. How can that be right?

A cluster computer invariably involves multiple devices that are connected together on a high speed network facilitating easy sharing of processing speed. The brain, on the other hand, is a single organic component. Well, the brain controls your limbs, your senses and all other parts of your body. If one were to remove cluster computing from the equation, each and every part of the body would have an independent brain of its own that would focus on utilizing just that part or component.

Now, take all these multiple brains and fuse them together into a single brain and you have the ultimate cluster computer. In any case, different parts of the brain controlling different parts of the body interact with each other at such high speed that we look at it as a single component. Hence, the logic behind cluster computing is not very far to find. Rather, it is present in our own body.

There will come a time when the computers with the most powerful processing speed will be linked together and will be utilized primarily as a single huge processor while all other nodes will be utilized for various other activities. When that happens, we would have a truly succeeded in creating a cluster computer brain that serves as the mother node of information and data processing for all other sub components of the cluster.

Cloud computing is when multiple devices have access to the same information on demand via a computer network. The devices can be laptop or desktop computers, tablets or Smartphones. These devices only require minimal software because everything needed is contained in the cloud or network. This new form of computing is proving to be very useful in the healthcare field.

Healthcare IT news articles discuss the improvements to the entire healthcare industry with the use of cloud computing. New medical devices include sensors that send patient data directly into the cloud where doctors and nurses can pay closer attention to a patient’s condition. Cloud computing also allows doctors in different locations to consult on one patient, so the patient receives the best treatment possible in the quickest amount of time.

Cloud computing not only helps deliver quality medical assistance, but it is also cost efficient because the cloud is accessed with a small computer or handheld device. The technology also addresses the challenges of obtaining information from medical devices quickly and efficiently, so medical professionals can analyze and process a patient’s data and immediately begin effective treatment.

With cloud computing, medical professionals will continue to improve healthcare.

The good news for those of us who rely on the computers is that we are able to access these programs for free. Some great open source products are Open Office, Gimp, Mozilla, and many popular blog sites. Whenever the user downloads any of these free products, they’ll be asked if programmers can retrieve error messages from the computer the product is downloaded to. The reason for this request is that it keeps open source technology active with problem solving and development. You always have the option to say, “no,” but “yes” allows the programmers to evolve technology much quicker, and therefore, many aspects of our daily lives evolve for the better, too.

Technology is needed to advance cures for diseases. It is open source programs that make this happen via cluster grids. We have made huge advances in communication via open source products, and entertainment is much more advanced, too. Sharing is really better than selling.

Probably the most prominent home supercomputer systems would be those created by gamers. They can literally buy a computer off the shelf at any retail store and create a cluster with all of their old computers. This is often more effective and cost efficient than buying or building one big machine to do it all. There is even experimentation with using WiFi to connect a cluster of computers. Depending on the age of some of the hardware, the gamer may use Microsoft or Linux. Many feel Linux is the better choice because it still runs with older hardware. It’s also an open source product, so there is a vibrant support community and very well documented technical sheets and support. If the Windows operating systems in the cluster are the same or within a generation or so of each other, then the cluster can be created, too.

The key is to build a computer environment that performs like one computer that would be very expensive to purchase. Existing and super inexpensive hardware can do the same thing, and it’s easy enough to replace one component or add one component versus buying your own “supercomputer.”

We have a wonderful election system in the United States, but now and then something goes wrong and the elections don’t go as smoothly as hoped. There have been occasional incidences in some cities in which it was learned that the voting machines were faulty. This put quite a hardship on the poll workers because that meant that all of the votes had to be counted by hand.

Now, just imagine if there was only one available poll worker. It would take that worker an undetermined amount of time to count all the votes. It would be unfathomable to hope to get the job done in due time.

The way it was handled was that many workers united to count the votes. This made the process much faster, and the work was eventually completed. It was completed much quicker than if one person did all of the counting alone. That is how cluster computing works.

If it were a computer performing the task, one could have eventually processed all of the data. However, many of them linked together make the job more thorough and much faster. If twenty computers are used, the work can be done at least twenty times faster.

With any luck, that will clear things up a bit for you. You should now put your new knowledge to good use. If your company is set up for cluster computing, when you go back to the office tomorrow, the first thing you should do is tell you coworkers that they can all work faster because you are there.

If you don’t have much cash and you need to upgrade to a bigger computer, you might try a couple of things. First, ask your friends if they want to sell their old computers as they upgrade. Also, check with thrift shops and office supply sales. Sometimes when a company upgrades its systems it will sell its old hardware for a good price. If you go with a Linux operating system, you’ll be able to more easily create a cluster that will work for you. If you’re unsure if you want to make the switch from Windows to Linux try it out first. It’s very portable and can be loaded onto a CD or thumb drive. You can then test it without actually loading it onto your machine.

As for speed, a group of older computers clustered together may seem like a major traffic jam in terms of processing and retrieving information. However, the Linux system will be able to run multiple processes much faster than other operating systems. It is also free. Not all tutorials and support will be free, but the product is.

This means that most of the participating computers need to have Linux components. These may be software programs, blog or web hosting sites, or the actual operating system of the computers in the cluster. Linux is meant to be accessible to anyone, so many Linux based programs will ask users for permission to gather information about the program on their machine. This is how open source is defined. By doing this, programmers can study problems and make improvements as needed. There is a level of trust needed in an open source environment, so many fail safes must also be in place. If a outage does occur, Linux can be restored without having to re-purchase the softwares or systems. Linux can also make corrections and push updates without slowing down a computer.  This keeps the cluster working as efficiently as possible.

Certainly, many computers on a grid may be Windows based. That’s O.K. Linux is compatible with Windows. This keeps the cluster from having to be exclusive to one system, and therefore, makes more information available to the other computers on the grid. More companies are recognizing that Linux technology is good for cluster computing.

An example would be how the World Community Grid was used to advance smallpox research. By browsing participating computers, the grid was able to match subjects with trials and hone down a huge process to 45 ideal participants. This happened in a small fraction of the time it would have taken otherwise. For those who were skeptical about a computer grid accurately contributing to research, all of that changed when IBM’s Watson won its Jeopardy match. It demonstrated just how fast a computer on a cluster grid can come up with the right answers. After the big win, registrations for the World Community Grid went up 700 percent. Computer Grid Technology is now positioned to help many organizations accurately speed up the problem solving processes needed to advance the quality of life on earth.

The drawback to this kind of grid technology is that it can slow down a participating computer. Even though the program is running in the background, it is possible for it to significantly affect the CPU usage on a machine at times.  It has also been known to occasionally over heat a computer, too. However, there is a fix for that.  Over all, grid technology and science are great partners when the problems we need to solve are critical.

Think of the internet as a big cluster computer or computing grid. It is a network of PCs that are connected to share information. If your hard drive isn’t big enough to store 100 movies, you can always stream them from another server via the internet. That idea powers much of the processing and information that we need to complete even our personal computing needs. In order to keep cluster computing accessible, up-to-date and affordable, many people prefer a Linux OS for cluster computing.

It is generally thought that the Linux systems are hardier than Microsoft operating systems. Because the Linux system is open source by its very nature, it is always available to any programmer for updates and improvements. Windows, on the other hand, has to be purchased. In a home environment, a consumer would have to buy the Microsoft software every time he added a new computer to his cluster. Via the internet, Linux software is free. It works just as well, and it is compatible with Windows. Therefore, it is cheaper to use the internet as a cluster and Linux programming as your cluster computer.

All operating systems have to be updated periodically. In a cluster situation, this is particularly important because of possible malware infections. Whenever Windows updates, it can really drag down an operating system, thus slowing down the whole cluster. Linux operating systems don’t slow down like that, so efficiency is ultimately better. If there is a problem in the network, and someone identifies it, he doesn’t need to wait for Microsoft to send an update to correct it. As an open source product, the programmer would be able to access the problem himself. It is this kind of open availability that truly makes Linux so hardy. There are many minds working the problem, not just a contained group tied to a company’s rules and protocol.

For those who know a little about cluster computers, they may think that IBM invented the concept. These groups of computers are networked together to improve performance and information availability that is better than what a single computer can provide. The engineering of this idea was formalized by an IBM employee, but it was customers who invented clusters, and cluster computer technology is older than you think.

Probably as early as the 1950s or 1960s, people were creating networks that would improve the power of their computing needs. Basically, when one computer was filled up, and people needed more space, they would create a backup out of one computer and add a new one. Therefore multi processes were happening outside of the a single computer. These separate machines were referred to as commodity computers. As a parallel work source, IBM began to develop a protocol for parallel processing. This was done in 1967.

This seems surprisng considering that the world wide web didn’t become publically popular until the early 1990s. Before that time, only a few households even owned a computer, and the ones they did have were fairly slow and clunky. However, once the personal computer became a common household item, cluster computing became fairly common among those looking to push the power of computing. Clusters weren’t just used by the Defense Department, large laboratories or NASA. The average user could create the same kind of environment on a smaller scale. This was definitely different than what was being done by customers in the 1960s, but the technology enabled anyone to enjoy big, fast computer processes. Today, open access programming continues to improve cluster computing and its availability via the internet and open source software. What started as business and government necessity has become a world wide collaboration to share knowledge.

The old computer will likely have an operating system that is compatible with the new computer, so the gamer can begin to cluster his older machines with the new machine. Maybe an older machine will be used for storage. Sometimes, the machine itself will no longer be operable, so the gamer will simply salvage the hard drive and use it as an external drive with a newer computer. As long as machines are compatible, the cluster can work. Some gamers are even experimenting with using a WiFi device to create clusters. If it works, it can be more space efficient. However, this kind of network may take more patience and troubleshooting.

Cluster computers are weaker computers that are networked to create a super computer, so gamers can be good testing sources for new ideas and trials in cluster computintg. Many find the challenge of creating a small cluster to be as fun as the games themselves. If you are replacing your PC, instead of recycling it, you might advertise it on a message board or Craigslist as a good computer for a gamer’s cluster.

Since the advent of the Internet, a revolution in reference has occurred. No longer are we relegated to libraries or time-consuming microfiche to scan, search or find dates and information. With just a few keystrokes we can access unlimited amounts of data and no other website has contributed more towards this revolution than Google.

Google has revolutionized search in such a way that Google is no longer just a search engine. In fact, Google is so synonymous with gathering information on the Internet that it is listed as a transitive verb in several dictionaries. In the Merriam Webster dictionary, its definition is listed as “to use the Google search engine to obtain information about (as a person) on the World Wide Web.”

Google’s rise to such an esteemed status is largely due to its unbelievable accuracy in providing relevant information. Many other search engines provide your needed reference in the second, third or fourth page in a returned search if at all. Google’s huge popularity is attributed to the fact that it always seems to provide the relevant information people need.

Even with this huge popularity and its recognized excellence for providing relevant results, there a specific Google tweak that you can incorporate to get a more refined list of websites relevant to your chosen topic. For example, if you are looking for property management sites, you will surely get the proper result should you Google the term. However, if you require information regarding a specific area, you should include more detail in your search such as “Scottsdale property management.” This will get your required results to you quicker.

With an estimated six out of 10 search engine inquiries using Google, it is by far the most used search engine on the Internet. There are dozens of search engines on the Internet. Some are flashier and others have been in existence longer, but none can rival Google’s excellence in providing relevant information.

It’s probably more accurate to call the internet a cluster grid because much like the electric power grid, the computers are not in the same house. They are sharing an external infrastructure to achieve the same result. In the cluster computer arena, this result would be information. The internet certainly doesn’t help speed up your operating system or personal network the way a true cluster computer configuration does, but it does allow you to access information from someone else’s server very fast.

One of the most important components of a successful cluster grid or computer is that each machine has to be free of malicious software. If one machine is infected, then every machine in that cluster can be infected. The internet is the same way. Every time a virus is introduced, via a computer in the cluster, every other computer that accesses the information distributed by the infected machine is at risk. Needless to say, security is very important for your machine. Always keep your anti-virus up-to-date, and allow software updates whenever they are available. Sometimes those updates are trying to improve the overall cluster. If you use open source software, like Open Office, always allow the programmers access to your machine so that they can identify and correct any problems that you are experiencing. Your problem could be something that affects everyone on your grid.

Each operating system within a given grid is called a node. The node may be a PC, an iPhone, or router. Under this definition, the internet certainly functions as a grid. So how are these clusters kept secure? Basically, the network sends tasks to random nodes on the grid to make sure they’re functioning properly and securely. Obviously, malicious programs can infect a grid and cause widespread problems. As work is sent to the various and random nodes, the system waits for two nodes to complete the work with the same result. If a node does not respond, or responds incorrectly, there could be a security issue.

Linux based systems are often touted as the best operating system for cluster grids. One of the arguments is that a Linux system doesn’t slow down a machine when updates are needed. Linux is also open source, so the positive work can be done faster and more thoroughly. If a user were to download a Linux based program, the programmers would ask permission to track any problems with that program. You are, then, participating in open source computing and helping to keep the cluster grid secure. If there is an error or problem with the program on your machine, the programmers can get a report and look at what happened. They can then correct the problem and also identify any security or grid function issues.

Since you are basically participating in grid computing whenever you log onto the internet, your paticipation in security would be to keep your antivirus up-to-date and always operating. Also agree to let open source programmers access your grid programs.

The term cluster computing or computer clusters may sound like a new computer craze, but it has been around for a while. Cluster computing is the technique of linking several computers together through a network, typically a local area network. This provides the advantage of parallel processing power of each networked computer.

Cluster computing is heavily used in businesses because linking many computers together can provide the same processing power as one super computer. Many businesses need the power of a super computer, but can not afford the price. To work around that, they simply create computer clusters to generate the needed processing power. There are few different types of computer clusters.

Load-Balancing Clusters

Load-balancing clusters work by routing all the work through a load-balancing front-end computer, which then distributes the workload between the remaining active computers. When a few computers are dedicated to manage the workload of a cluster, limited processing power is optimized. This is a great option for companies with limited IT budgets.

High-Performance Clusters

High-performance clusters are made specifically to exploit the parallel processing power of multiple computers. This is the type of computer cluster that is best used when the computers need to perform functions that require the computers to talk to each other as they perform their tasks. An example is when calculation results from one computer will affect the results from another. Have you ever heard of the Seti@Home Project? This is a great example of a high-performance cluster. The project consists of over 5 million home computers, volunteered by their owners, which devote processing power to analyze data from the Arecibo Observatory radio telescope.

High Availability Clusters

High availability clusters ensure constant access to all service applications. The clusters are specifically made to maintain redundant computers that can be backup systems in case of failure. The minimum number of computers in a high availability cluster is two: one computer is active and one is redundant.

Improved Technology

As computer clusters have been developing and evolving, so has networking technology. And, as the technology has been getting better and better, the price has gone down. This makes the technology more affordable. Computer cluster technology involves using a single virtual local area network, which treats each computer as a node. Data is passed through the network, without any information bottlenecked between the computers or nodes.

Awesome Processing Power

The processing power of a high performance computer cluster is the same as a mainframe computer. With many computers in a cluster, the processing power may even exceed that of a mainframe.

Cost Efficient

Purchasing several good quality computers such as HP desktops at once, is less expensive than buying one supercomputer. The average PC today is a lot more powerful than the first mainframe computers. This means, companies can get the same or even greater processing power by using several desktop computers instead of a mainframe computer, and it is a lot cheaper.

Practically Fail Proof

When one computer in a cluster fails, those operations can simply go to another computer, which ensures there is no interruption in service. When a mainframe computer goes down, the entire system will stop working.

Expandability

Many people feel that the best benefit of utilizing computer clusters is that they can be expanded easily by adding additional computers to the network. A mainframe computer has a fixed capacity and will only be able to handle so much power at a time.

Quite often, new owners are tempted to go all out on their IT systems, but that can get very expensive. At the same time, it is not actually known by them yet if an extensive IT system is going to be required. One of the great things about cluster computing is that it provides the ability to start with the exact system needed and build upon it as the office needs grow.

Computer clustering is so flexible that the IT system may never need upgrading to a mainframe. As more processing power is needed, more personal computers can be added to the system to supply it. This can be done many times over to satisfy whatever requirements come about.

The opposite is true as well. Sometimes an office needs to be downsized. If a mainframe is being used, it cannot be downsized. However, a computing cluster with twenty computers linked together can be trimmed to fifteen, ten, five or however many computers are needed to accommodate the system.

Good business owners keep a tight check on all aspects of the company. Cutting spending and carefully controlling money is one of them. Before an entrepreneur even opens the doors to the office, he should have a good idea what his IT is going to cost. In many cases, starting with cluster computing rather than using a mainframe computer is like putting money in the bank right away.

Internet computing is essentially using the Web to access a database to process information. The processing is done via a software program that uses the processor of an otherwise dormant computer. A unit that is used for work for eight hours per day, and then shut down for sixteen hours, can effectively use those sixteen hours to run tasks and perform calculations.

Internet computing allows for computers all around the world to be logged into a database to perform this work without the need of a huge network. The network is, in effect, the Web. All of the processors working with that database are essentially the computer cluster.

Companies and organizations using this kind of system include colleges, government agencies and private institutions. Much of the work being done involves research and the processing and analysis of research data. Some of these organizations are for profit; some of them are nonprofit.

It is common for the nonprofit organizations to use private desktop computers to do their Internet computing. Some of them do interesting and important scientific research that intrigues some people who sympathize with the cause of these groups.

Because of this, those people may volunteer to allow their processors to be used during their machine’s normal down time. This cuts a lot of corners for these organizations by saving them money and an extraordinary amount of time that it would normally take to do this kind of work.

As fast as knowledge already grows, it makes a person wonder what is on the horizon. With the help of Internet and cluster computing, we will see enormous advances in the fields of science and medicine in our lifetimes.

If your place of business is just a simple office with a few employees, you may not have a need for high performance computing. Maintaining a simple database, running a few software programs, sending e-mails and having a small network is not anything that a traditional setup cannot handle.

On the other hand, if your industry requires intensive data mining, the handling of statistics and heavy number crunching, you will need the appropriate processing power. Both kinds written about in this article can provide that kind of performance.

One difference between the mainframe and the cluster is the cost. The former is considerably more expensive. The latter is more of a “pay as you go” system, meaning that you only add what you need now and can add more later as you need the additional performance.

You could say that opting for a mainframe computer is more of a commitment. That’s not to say that it is bad, just that it is expensive. Cluster computing is less costly because it is based on traditional desktop computers that are linked together to combine their performance.

If your company is going to be massive and grow quickly, a mainframe computer may be the only way for you to go. On the other hand, if you expect growth but at a slower pace, you best option may be cluster computing. That way you can add more processing power as your company needs it.

And that’s bad news, because malware is designed with the intent to do you harm, at the expense of having a more slowly operating computer, too! Malware are typically very small programs which affix themselves, uninvited, into dark spaces in your computer. They often run undetected, keeping track of your keystrokes – there’s not a much better way to hand someone your banking password than to let them see your keystrokes – and allowing the information there gathered to be used in whatever way the perpetrators desire. If you’re suddenly getting a rash of spam emails where in the past, you’ve not suffered this fate; it’s probably due to a new form of malware inside your machine.

Of course, all of this comes at a cost, besides the potential of an empty bank account! The latest, greatest computer that you paid out many hard-earned dollars for, suddenly doesn’t work at anything approaching a reasonable speed. That’s because malware programs freely use as much hard disk speed as they desire, leaving your legitimate programs with much less capacity to operate. Rather than wipe your hard drive and start all over with a system re-install, consider PC Tools Free Antivirus as a faster, easier solution. It will clean up the mess that malware tries to create.

An HPC cluster is most often used in place of a mainframe computer. Sometimes it is done when a company needs a fast solution to a special computing need, and sometimes it is done to prevent having to lay out a large amount of money for a mainframe.

There are some companies that use their computers primarily as storage devices for data and as a communications tool. They may also do the books, log sales and file papers electronically with them. All in all, though, they have no great demand for any kind of intense computer processing.

On the other hand, there are companies that do some very intense work with their computers. Much of this work includes the heavy processing of data. They may have created their own software programs to analyze statistics or run tests on different things. These businesses need all of the processing power they can get.

A good example of a situation in which a HPC cluster might be used is in the forecasting of weather. It is hard to imagine all of the data that has to be “crunched” to get the accurate predictions for the nightly newscast.

Other companies that might have need for a HPC cluster might be financial firms; especially those that continually monitor the stock market so their agents can make predictions for their clients.

When it comes down to it, most of us don’t need high performance cluster computing like some of the big corporations do. We can get by with a nice, off-the-shelf system that will give us enough horsepower to read our e-mail, watch some videos and play some games.

The SETI at Home Program

SETI stands for the Search for Extra-Terrestrial Intelligence. SETI at Home is a unique program that clusters computers from all around the world together in the search for life in the universe. This is done by processing signals received from outer space. The hope is to discover certain radio frequencies that are not produced naturally.

However, it is such a big job that those who run it need a little help. Everyone who has a computer and an online connection can use his or her processor to be a part of the computer cluster that SETI at Home uses to process the signals. Those who help do not receive those signals directly, but log in process the data that has already been collected.

How You Can Help the Program

All you need to do is join the SETI at Home program. This can be done from the Berkley University of California Web site. Search for SETI@home. You will be asked to read the rules, and you will need to commit to running the application on your computer for at least two hours per week.

You will then download the software to your computer and install it. After that, it is a simple as opening up the program and running it. It can run unobtrusively in the background while you do other things. If you prefer, you can turn on the application when you are finished computing for the day. It can run at night while you sleep.

You, too, can be a part of the largest computer cluster in the world. Who knows, you might even be a part of history; it might be your computer that comes in contact with ET.

Cluster computing is a great way for new businesses or small business to save money while still getting enough computing power to handle their needs. It can be expensive to purchase a large computer to run a business. However, there is a more affordable way for small business owners to deal with this.

Cluster computing has become a popular way to get more processing power for less money. To give you an illustration of what it is, consider the game of tug of war. The more people you have pulling on one side of the rope, the more power you have. You no longer have just an individual’s strength, but you have the cumulative strength of all of the individuals.

That’s the way it is with a computer cluster. Single computers are linked together to form one large processor. This is effective because it saves a business owner from having to purchase a large mainframe to handle the needs of the company.

Now that personal computers are so much more affordable than they used to be, the owner can buy however many he needs to handle the job and, in most cases, still save money over the cost of a mainframe.

Computing clusters can be made up of as few as two computers. The owner can set up as many as he needs initially. As time goes by and his needs increase, more units can be added. There may come a time when a mainframe is more sensible, but in the beginning, this is a good way to go.

Anyone anticipating opening a business that will require computers should consider going the route of cluster computing rather than starting with a mainframe. It may be that a supercomputer is going to be required, but it would be a good idea to look into it before putting a lot of money into it.

One of the biggest expenses of running a business can be the cost of computers, networking and IT. After all is said and done, what may seem simple and affordable in the beginning can end up being very expensive. Purchasing a mainframe computer is a good example of that. It is not always necessary to start large, and there is a lot more flexibility with cluster computing.

Quite often, new owners are tempted to go all out on their IT systems, but that can get very expensive. At the same time, it is not actually known by them yet if an extensive IT system is going to be required. One of the great things about cluster computing is that it provides the ability to start with the exact system needed and build upon it as the office needs grow.

Computer clustering is so flexible that the IT system may never need upgrading to a mainframe. Another benefit to cluster computing is the innovation of cloud computing, which makes it easy for updates and repairs to be done over an entire network from virtually anywhere. This can help major computer companies from disabling the entire systems for hours at a time, which can essentially cost the company money, and sometimes clients. As more processing power is needed, more personal computers can be added to the system to supply it. This can be done many times over to satisfy whatever requirements come about.

The opposite is true as well. Sometimes an office needs to be downsized. If a mainframe is being used, it cannot be downsized. However, a computing cluster with twenty computers linked together can be trimmed to fifteen, ten, five or however many computers are needed to accommodate the system.

Good business owners keep a tight check on all aspects of the company. Cutting spending and carefully controlling money is one of them. Before an entrepreneur even opens the doors to the office, he should have a good idea what his IT is going to cost. In many cases, starting with cluster computing rather than using a mainframe computer is like putting money in the bank right away.

The last thing any business needs is for things to break down or go wrong. There is rarely ever a convenient time. If anything has the potential to stop working, it is computers — and at the worst possible time. That is why cluster computing is more dependable than mainframe computing.

When a mainframe computer is being used, that is all there is. In other words, if it breaks down or quits functioning, there is no backup computer. The mainframe was it, and now it is gone. Outside of making some of the employees who get to go home early happy, this is not a good thing for the company. Work stalls or comes to a halt, and impatient clients can be angered or even lost.

On the other hand, if the business were using a cluster computing system, the problem described above would not happen. That is because another processor could just take over the work the failing one was doing. It happens without skipping a beat, and everything continues like clockwork.

To get a better understanding of this, imagine a string of Christmas tree lights that runs in parallel. When one of the bulbs in that string burns out, the others will still keep shining. The only thing that has to be done is to replace the burned out bulb, and the whole string will work again. In the meantime, everything but the one bulb kept working fine.

However, the mainframe computer would be more the like the lights used many years ago that ran in series. When one of them burned out, they all stopped working. It would be like that with the mainframe. When it goes down, the only processor that was being used stops working.

If your business absolutely must have its computers operational, and you are looking for a dependable system, consider avoiding the mainframe and go with cluster computing. That way your tree’s lights will never go out.

Most of us get by just fine with the home computers that we buy from our favorite electronics store. They are fast and able to do anything the average user needs to do: check e-mail, surf the Internet, read e-books and write documents. However, there are some things, like video games, that are more intense and may need the power of a homemade supercomputer. Cluster computing is a good way to get that kind of processing power at home.

It may be an exaggeration to refer to it as a supercomputer when it is in your home. After all, a real supercomputer is far beyond anything a user might have around the house. The big companies use them because they need the processing power to handle lots of data, transactions, communications, statistics and many other things.

However, all things tend to be equal when it comes to the amount of processing needed as compared with the amount of work that there is to be done. In other words, by setting up a computer cluster, a home user might have the equivalent of the supercomputer that a big corporation uses.

Linking two computers together can double the processing power that is being used to operate software and do calculations. Two high-speed processors can make a world of difference in the way a video game, for example, responds when being played.

Actually, the cluster doesn’t have to be limited to two processors. There can be three, five or ten of them; however many that are needed.

If playing intense video games is your thing, or if you need some heavy-duty processing power for any other reason, you might want to make a homemade supercomputer by using cluster computing. Even if you don’t truly need it, you might have fun setting everything up. Then you can show your friends your new hot rod.

Computer Clusters at Work

Computer clusters are often useful in workplaces because they give lots of workers access to the same information. This makes it possible for employees to find the information that they need to complete specific tasks. Using a computer cluster at work can also help managers prevent employees from spending time on unrelated tasks such as playing games or browsing the web. They can, therefore, make employees much more efficient so that the company saves money.

Computer Clusters at Home

Video gamers will undoubtedly know that computer clusters offer big advantages when it comes to multi-player games. Gamers all across the world hold events in their homes so that several people can play graphic-intense video games at the same time. You can find them in every type of home from Phoenix apartments to farms in the countryside. Wherever gamers live, you are likely to find them taking advantages of the benefits that computer clusters offer.

Computer Clusters at School

Computer clusters are terrific computational machines. Allocating the resources of several computers to a single problem reduces the amount of time that it takes to compute large amounts of information. Although your typical high school student probably won’t need a computer cluster, someone studying physics and theoretical math at the graduate level will find that computer clusters offer several benefits. Instead of spending weeks trying to solve a single problem, a computer cluster can provide the answer within a matter of minutes or hours. They are, therefore, imperative research tools for those studying science and math.

Because of advances in technology, cluster computing has become more common for business that need the processing power but don’t want to invest in large expensive computers. Most of the time, this saves them money and affords them a lot of flexibility in how they handle their IT affairs. Of course, the other decision they have to make is regarding what machines should be used for a computer cluster.

Computers are more advanced and more affordable now than ever before. What used to cost thousands of dollars can now be had for a matter of hundreds; and it is much more sophisticated and faster. This is a great thing for a company that needs to purchase several computers to build a cluster.

However, the downside to purchasing a new one is that it can become outdated so quickly. New, faster processors are always being developed; new hard drives can hold more data; RAM becomes more advanced. It becomes nearly impossible to keep up with them.

In addition to that, as they get faster and able to provide more memory and storage, software gets more bloated and requires even more speed and memory. It’s like a never-ending battle.

The way to prepare for this is to purchase the best computer available. More importantly than that is to get a computer than can be easily upgraded. Many that the large manufacturer’s make cannot be easily upgraded. A lot of money can be saved later by purchasing one that is nonproprietary. That means that more memory, better hard drives and a better processor can be added later.

Choosing to go with cluster computing rather than to invest in an expensive mainframe computer can be a wise thing to do. Businesses that need room for growth will be able expand their processing power as the business necessitates. In the end, these companies will save money and have a more reliable system in place.

The great thing about this day and age is that almost everything is at our fingertips. You can find out information on nearly anyone and anything in just a few minutes by doing a search on the internet. News travels extremely fast, and keeping in touch with friends, family, and business associates has never been easier. Some people find this to be a great and wonderful thing. Others find it to be a little scary.

Since everything is so easily available, it can feel at times like your life is on display. Companies are now tracking social media sites, and for some it can be disconcerting to see ads targeted to things that you have been searching for online.

Whether you find the availability of information great or disconcerting, most people do agree that it has made things a lot easier for many people. If you own a business, you can talk with business associates much easier, and you can also get customers from around the world with much less money going into your marketing than in previous times. For individuals, you can communicate much easier with friends and family. Not only that, but you can find the businesses that you want to deal with, and generally don’t have to worry too much about how close or how far they are from you. If you are in school, having the information available that the Internet can provide is extremely beneficial. Writing papers for school has never been easier.

Feeling about privacy issues on the Internet vary from person to person. Most agree that privacy is a concern online, because of everything that is readily available. Others find that it does not matter too much, simply because that information has always been available.

Thanks to scientists, engineers and large companies taking advantage of capitalism, the speed of our computers increases constantly. Unfortunately, so does the work load brought about by more intense software. With that in mind, private users and companies are always looking for ways to make computers work faster. Some opt for either parallel or cluster computing. So, what is the difference?

What is Cluster Computing?

In a nutshell, it is the linking of multiple computers together to work as one unit that is more powerful. Each one handles its share of the processing, thus the workload can be done twice as fast. The network can be made larger by adding more nodes, or computers, to the system.

What is Parallel Computing?

This is done with multiple processors. Computer clusters are a form of parallel computing, but the latter is more regarded as one unit with multiple processors. This is called dual processing. It is in essence the same thing as a cluster, but it is inside of one unit.

Actually, a computer with a dual processor could be used to make a cluster. However, a private user would not be as likely to use that configuration as a business might. Dual processors on a home system are plenty fast to handle anything that an average user would do, and more.

It essentially comes down to the “two heads are better than one” theory with parallel computing. As far as cluster computing, it is more like “it is less expensive than a mainframe.”

Either way, more processing power will be available. A large company will be more likely to set up cluster computing because it gives them more options to expand later. A private user could go that route, but it would be more feasible and less expensive to opt for a computer with a dual processor.

Voice over Internet protocol, commonly referred to as VoIP, has been is one of the major developments in verbal communication. VoIP is a method of communication that allows transmission of audio (or voice) over Internet protocol networks. Many people refer to VoIP as Internet telephony or broadband phone.

Similar to data transmission over the Internet, VoIP transmits voice signals by converting and translating audio signals into digital packets. Just as in web browsing, these packets are then received and translated back to an audio signal.

The transmission of voice on the same lines as data, as opposed to traditional telephone networks, helped aggregate services for many consumers. Consumers were able to bundle both their voice and data needs into the same provider. Anyone who had high speed Internet access had the capability to also use that service for voice.

Companies such as Vonage started to promote VoIP services as early as 2004. Consumers would simply need to obtain a VoIP compatible phone and they could immediately start communicating. The quality of audio was comparable if not better than traditional phone lines.

Corporations immediately recognized the cost savings from VoIP and started to implement VoIP technologies. VoIP has evolved into an “all-in-one” solution for companies, where voice, data, fax and voicemail are bundled into one service.

There are many benefits of VoIP. As previously mentioned, cost is a major reason why people choose VoIP over traditional. VoIP is also much more flexible in that you can take the connection with you wherever there is a fast Internet connection and VoIP also allow multiple calls to be placed on the same line.

VoIP is a great option for any family or business seeking to streamline their budget.

Electronic mail, or email, is one of the primary uses of computers and the Internet. Email constitutes much of the total Internet traffic each day. Some might say that much of the early success of the Internet can be attributed to the popularity of email. It is grown to be an integral part of our world and can be both a blessing and a curse.

Email is exactly what its name implies – electronic mail. Messages are delivered over the Internet or any computer network for that matter. In its most simple form this communication takes place between one computer to another – but the evolution of email has brought about server technology and added capabilities to email large audiences with one simple click.

History of email has its beginnings before the creation of the Internet, as we know it today. MIT worked on simple email concepts as early as 1961. The concept centered on the idea of letting multiple users access and save files to a single remote computer. Early versions only allowed a few individuals to access a single computer. Later email enabled organizations to communicate across the same company network. Eventually Internet opened up where anyone with a standard email client could communicate with anyone with an Internet connection.

Email has greatly impacted the way we communicate with one another. Businesses can more quickly communicate with clients and decisions are made at a more efficient pace. Social networks can maintain stronger bonds regardless of geographic distances.

The benefits of email also come with a cost. The ease of email has led to the decline of traditional methods of communication. Phone calls and hand written notes have declined as more and more people utilize email. Some research has shown that this electronic mode of communication can be detrimental for overall social skills, as face-to-face interaction has slowly decreased.

Email will grow to be an increasingly larger part of private and business life. One should keep both the costs and benefits of email as they make it part of their life.

No matter what your spending habits are like, you may on occasion find yourself turning to your credit cards. This can be both frustrating and stressful. You know very well what the interest rate on those cards is, and it’s not pretty. But sometime, you just can’t help it. Maybe an emergency happened, or maybe you just need to get that one last Christmas present. No matter the reason, pulling out a high interest credit card is not a fun situation.

Because of this, many people today are turning to prepaid credit cards. These cards don’t have high interest rates. In fact, since they are prepaid, they don’t have any interest at all. You are able to use as much money as you allot to the card, and load on to it. You can’t use more than that, so you can’t go over your spending limit. This is also a great thing for many people, who have a bad habit of spending just a little too much.

Because of this, many families are giving these cards to the teenagers in the family. This can help them to start understanding budgeting and how to use a card, without killing the family budget. The child knows exactly what they have to spend, and can even track their spending online. Gaining a little Independence and a lot of responsibility is a great way to learn.

A prepaid credit card can be used anywhere that a normal credit or debit card can be used. This means that you can use it online or in a store. So, next time, instead of pulling out that high interest, high stress credit card, make sure that you have your prepaid card on hand. It will save you tons of money, and even more stress.

Maybe you have heard the term and wondered what the big deal is about high performance cluster computing. After all, if it is something great, you sure don’t want to miss out. However, not everyone or every business needs this kind of horsepower. Then who does need it?

An HPC cluster is most often used in place of a mainframe computer. Sometimes it is done when a company needs a fast solution to a special computing need, and sometimes it is done to prevent having to lay out a large amount of money for a mainframe.

There are some companies that use their computers primarily as storage devices for data and as a communications tool. They may also do the books, log sales and file papers electronically with them. All in all, though, they have no great demand for any kind of intense computer processing.

On the other hand, there are companies that do some very intense work with their computers. Much of this work includes the heavy processing of data. They may have created their own software programs to analyze statistics or run tests on different things. These businesses need all of the processing power they can get.

A good example of a situation in which a HPC cluster might be used is in the forecasting of weather. It is hard to imagine all of the data that has to be “crunched” to get the accurate predictions for the nightly newscast.

Other companies that might have need for a HPC cluster might be financial firms; especially those that continually monitor the stock market so their agents can make predictions for their clients.

When it comes down to it, most of us don’t need high performance cluster computing like some of the big corporations do. We can get by with a nice, off-the-shelf system that will give us enough horsepower to read our e-mail, watch some videos and play some games.

Chances are if you work in an office, you have an IT person behind the scenes who keeps everything running smoothly for you. When you sit down at your computer, there are probably a lot of things going on of which you are not even aware. For example, your company may be using cluster computing software. How does that make you feel?

Actually, don’t let that frighten you. If your company is running a computer cluster, that software is what makes your computer play nice with the other ones in your office. The cluster is a system in which at least two computers are linked together to work in conjunction together. They share resources to make data processing faster.

You have heard of the Windows operating system, haven’t you? That’s what makes your computer work when you turn it on. It gives you all the nice windows and buttons so you can tell Windows what you want your computer to do for you. The operating system is real handy.

Well, because your boss is running a computer cluster in your office, that cluster needs software — an operating system — to tell all of the other computers what to do. It’s the trickledown effect.

It may seem complicated, but it’s really not. Essentially, the cluster software controls what the computers do. It tells them when to perform jobs, process data, run errands and make coffee. Well, maybe not that last part, but some geek somewhere probably has his computer set up to do that.

That’s about it. Cluster computer software keeps everything running smoothly behind the scenes. By the way, the reason your boss is probably using a cluster in the first place is because it is less expensive than buying one great big mainframe computer. Now that you know that, you don’t have to be so shy about asking her for a raise.

Cluster computing is only one of the types of computer networks available. Just as there are different types of car insurance, like motorcycle insurance, truck insurance and classic car insurance, there are also different types of computer networks as well. Cluster computing means arranging or linking the computers in different ways so that all of the computers are sharing the same hard drive and all of the computers are also sharing a single common directory.

In cluster computing, all of the computers in the cluster are also sharing the same network, and as such they can run all of the same programs. Additionally, all of the computers in the cluster computing network naturally trust one another, and so they do not need to be verified. The process of creating a cluster computing network can be simple if the network administrator already knows what he or she is doing. If more computers need to be connected, then the setup process can become more complicated as well.

Cluster computing often makes sense but is not for every computer networking situation. As such, it becomes necessary for you to consider all of the various options that are available to you before you begin working on setting up any kind of network. Choosing the right network setup is going to help make sure that you get the most out of your network and do not end up spending time or money on a networking setup that is not going to work for your home or office.

One thing I can’t live without is our emergency credit card. Nobody is quite sure where the card was packed, and I needed it yesterday. While I wait the two business days it will take our credit card company to send me a new card, I had to go to paydayone.com to get some cash to fix the car. It was a little problem, but you know how car repairs go. At $60/hour for labor and a 200 percent mark-up on parts, a ten minute, $10 repair will end up costing us $300.

Back to what we can live without. So, I know that I was convinced at the old house that we needed everything that we had out. Anything sitting around must have been something we used from time to time at least. Now that we are in the new house though, half of our boxes are still packed and I almost never wonder where to find something.

If I wasn’t such a worrier, I would consider throwing the boxes out and not bothering with the stuff. Our house is certainly cleaner with half of the boxes still packed up!

As I do get a few opened up, my daughter is loving the boxes. I let her color all over the outside of one, and then I cut a door and windows into it. I even cut a hole in the top and set a flashlight over the hole to give her a reading light. The box house was a big hit!

It does make me wonder though, if our daughter will be one of those kids at Christmas who love the boxes more than the gifts!

We have a wonderful election system in the United States, but now and then something goes wrong and the elections don’t go as smoothly as hoped. There have been occasional incidences in some cities in which it was learned that the voting machines were faulty. This put quite a hardship on the poll workers because that meant that all of the votes had to be counted by hand.

Now, just imagine if there was only one available poll worker. It would take that worker an undetermined amount of time to count all the votes. It would be unfathomable to hope to get the job done in due time.

The way it was handled was that many workers united to count the votes. This made the process much faster, and the work was eventually completed. It was completed much quicker than if one person did all of the counting alone. That is how cluster computing works.

If it were a computer performing the task, one could have eventually processed all of the data. However, many of them linked together make the job more thorough and much faster. If twenty computers are used, the work can be done at least twenty times faster.

With any luck, that will clear things up a bit for you. You should now put your new knowledge to good use. If your company is set up for cluster computing, when you go back to the office tomorrow, the first thing you should do is tell you coworkers that they can all work faster because you are there.

Web logs or “Blogs” have evolved into a large online industry. What started as a simple idea is now a large part the internet. From stay at home mothers to large corporations, blogs constitute a large part of internet traffic every day.

Blogs were a simple tool for individuals to share periodic updates of their lives, an online journal of some sort. Users could share photos and give simple summaries of their lives using blog tools. It was a great way for friends and family members to share and keep up with each other.

The ease of publishing a blogs made them quickly popular. Up until the advent of blogs, individuals would create and publish static websites. These individuals usually were tech savvy and had income to support hosting a website. Blogs opened the door to, non-tech individuals allowing them to post with ease – and for fee. Blogs also allowed individuals to leave their material open for comments, adding an interactive element to their sites.

The origins of blogging started in the early 1990s. Many online user groups and discussion boards provided a quasi-blog platform for users to share thoughts and material with each other. Online diary provided the launch pad for modern day blogs.

Blogging grew in popularity through the late 1990s into the early 2000s as many online services started to launch. Perhaps the most popular was Blogger.com, which was started in 1999 and later sold to Google in 2003. These free blogging tools gave anyone with an internet connection the ability to share with the world anything they took the time to share.

Blogging has revolutionized the way people get their news causing many traditional news media outlets to rethink their delivery methods. No longer does someone have to have a journalism degree to share news, blogs allows anyone to report.

The utility of blogs are diverse. You can find a blog revolving around any topic imaginable. Blogs have grown from a tool to tell personal stories to a center piece of company’s revenue strategies. They will be part of Internet culture for a long time.

Many people today purchase items online. It doesn’t matter if you live in Bohol or anywhere else in the world, you will find that buying online can be a lot easier, and a lot less stressful than going to a traditional brick and mortar store. You don’t have to worry about the crowds that you would have to push through at a store, and you are frequently able to find better deals online. This is not to say that you can’t find great deals in stores, but having the entire Internet at your fingertips makes it easier to find discounts and coupons.

Many companies, when tracking social media, are able to find out quite a bit about their customers, and therefore tailor to their needs. For example, many online stores are able to find out what parts of the world their customer base is from. This allows them to tailor their ads and products to exactly what these people may want.

With the option to purchase items online, you never have to worry about not being able to find what you want. In fact, you can find almost anything on the Internet, and usually it doesn’t even take very much work to find exactly what you are looking for. This is a great convenience for most people. Running from store to store can be frustrating and difficult, and there is no guarantee that you will even end up with what you want by the time you are done. On the other hand, if you have internet access, you will most likely find what you need in just a few minutes. Sure, it will generally take a little bit of time for shipping, but this way you don’t have the uncertainty of whether or not you will find your items.

If you are a business owner, or just starting up a new business, you certainly know by now that you have a lot of decisions to make. Any choices that you make now can affect your company for years to come. Choosing the right IT setup is one of those. If you plan on having more than a few workers and doing some intense processing with your computers, you will have to decide whether to go with cluster computing or a mainframe computer.

If your place of business is just a simple office with a few employees, you may not have a need for high performance computing. Maintaining a simple database, running a few software programs, sending e-mails and having a small network is not anything that a traditional setup cannot handle.

On the other hand, if your industry requires intensive data mining, the handling of statistics and heavy number crunching, you will need the appropriate processing power. Both kinds written about in this article can provide that kind of performance.

One difference between the mainframe and the cluster is the cost. The former is considerably more expensive. The latter is more of a “pay as you go” system, meaning that you only add what you need now and can add more later as you need the additional performance.

You could say that opting for a mainframe computer is more of a commitment. That’s not to say that it is bad, just that it is expensive. Cluster computing is less costly because it is based on traditional desktop computers that are linked together to combine their performance.

If your company is going to be massive and grow quickly, a mainframe computer may be the only way for you to go. On the other hand, if you expect growth but at a slower pace, you best option may be cluster computing. That way you can add more processing power as your company needs it.

Companies are always looking for ways to save money and be more efficient. This has inspired them to look at some ideas regarding Internet and cluster computing that have enlightened them to some good possibilities. Many of these companies are starting to make good use of computers that are inactive.

Internet computing is essentially using the Web to access a database to process information. The processing is done via a software program that uses the processor of an otherwise dormant computer. A unit that is used for work for eight hours per day, and then shut down for sixteen hours, can effectively use those sixteen hours to run tasks and perform calculations.

Internet computing allows for computers all around the world to be logged into a database to perform this work without the need of a huge network. The network is, in effect, the Web. All of the processors working with that database are essentially the computer cluster.

Companies and organizations using this kind of system include colleges, government agencies and private institutions. Much of the work being done involves research and the processing and analysis of research data. Some of these organizations are for profit; some of them are nonprofit.

It is common for the nonprofit organizations to use private desktop computers to do their Internet computing. Some of them do interesting and important scientific research that intrigues some people who sympathize with the cause of these groups.

Because of this, those people may volunteer to allow their processors to be used during their machine’s normal down time. This cuts a lot of corners for these organizations by saving them money and an extraordinary amount of time that it would normally take to do this kind of work.

As fast as knowledge already grows, it makes a person wonder what is on the horizon. With the help of Internet and cluster computing, we will see enormous advances in the fields of science and medicine in our lifetimes.

Business process such as database management rely heavily on IT resources for daily computing processes, but as was stated the budgets of these IT departments are usually not large enough to keep up with their company’s demand for more and greater computing power.

A great number of the major business enterprises today actually would require the processing and computing power of a supercomputer. However, very few of the companies have a super-sized budget for such computers.

Because of this need for processing power on one hand and the budge constraints on the other, many companies and their IT departments are turning to computer clusters. Computer clusters are networks of cheap, yet very high-powered desktop computers.

There are many different types of computer clusters such as high-availability clusters, load-balancing clusters and high-performance clusters. Each of these different types of clusters has different designs and configurations for different computing scenarios.

The benefits of computer clusters include:

–Higher processing power. These clusters can be more cost-effective than a mainframe, providing a higher return on investment.

–Network technology improvement. In addition to the reduction in cost, these clusters are driving the implementation of new and improved networking technology.

–Scalability is probably the biggest advantage to these computer clusters. These clusters can be expanded very quickly, while traditional mainframes cannot with out greater expense.

–Reliability. The entire computing system with in a department or company will go down if the mainframe computer fails. However, with clusters a node or single computer can fail and the system can continue by transferring services to another node.

Software is considered to be a valuable intellectual property and should be treated as such. The Business Software Alliance and the Annual Global Software Piracy Study recently release numbers that state that the loss in revenue due to piracy went above $50 billion.

There are many different types of software piracy:

–Upload/download. This is a common for of piracy where users make illegal copies of software available to others via online services.

–Counterfeiting. This is the process where software is duplicated and sold in forms that make it appear they are true, legal copies.

–Unbundling. This is where a vendor sells software that was intended to accompany a specific hardware system.

–Soft-lifting. This is were a user purchase a single legal copy of a software program, but then installs the same copy onto several computers.

–Hard-disk loading is where unauthorized software is loaded onto hard disks. A common scenario is a hardware dealer will load this software onto computers to entice buyers.

–Renting. This is much like video rentals, except that it is unauthorized software.

Many of us believe that piracy has no victims; however this is patently untrue. As stated above the cost of software piracy is more than $50 billion in revenues due to developers. Another myth is that the copy protection placed on some software makes it more expensive. These costs are minimal when compared to the losses. When developers do not lose money to piracy they can then afford to produce better software at more competitive pricing.

A lot of companies do not allow access to these sites from an internal standpoint; and others may tell their employees that they are not allowed to discuss the company on these sites, even during personal, private times.

The jump was very, very fast from traditional media such as radio and print to the Internet and social media. And it’s not something that is going to fade away after the initial excitement. And interestingly, IT departments are uptight about social media, while the marketing department of the same company is trying to exploit these sites to the company’s advantage.

We understand there’s a certain appeal to social networking and media. And believe it or not, social media is considered to be part of Internet addictions. There’s also the “generation gap” of the Internet — older workers think that there should be no distractions during the workday; while the younger generations expect to be distracted.

On things companies should be aware of when denying internal access to social media is that it can actually set them up for other security issues. If employees really want access it is possible that they will come up with a solution to override the permissions and get on those sites anyway. These actions will basically open up security issues and may make the company’s network even more vulnerable.

Also there is disengagement between online behaviors that are secure and the lightheartedness of social media.

Companies need to create guidelines and implement policies that won’t prevent them from gaining new customers and communicating with existing clients.

When a user types in a world or phrases at a search engine, the servers of the search engine will match your search terms with the pages it has searched and the delivers the results. The list is organized from best to worse and according to various criteria.

Since the list is organized this way, users are more likely to click on the links that are listed first. These sites listed at the top get more visitors and in turn more business through leads and sales.

There are many techniques that are advantageous to having a site appear at the top of search rankings. Techniques for a high listing include development of sites that are information rich and the identification of good keywords and using these words throughout the site.

There for good SEO copywriting is important on many fronts. It’s using the terms people are using to search within your copy, not trying to fool the search engines by using unrelated terms. This will not only make your copy unreadable, it will deter people from visiting your site for any length of time. Your visitors need to find relevant, well-written copy.

Your site can go up the rankings by using a few tips such as using original copy that is relevant to the search terms. Place your keywords within your copy so that it makes sense. Keywords are most important in links, headings and metadata. In additional each pages of your site should be unique — makes sure your pages have their own keywords and titles.

As a web designer, you obviously want to create a very visually appealing site; however you also need to keep in mind the importance of search engine optimization. It really does not do you or your client any good if no one can find you on the World Wide Web.

There are many techniques to help give your site a higher ranking on search engines, and that is what SEO is all about — get your site top rankings, so people will go to your beautifully designed and informative site.

One of the best things to do is make sure your copy is a wealth of information that your visitors will want to read. Additionally, you need to find out the words that people will most likely use during their search and use those keywords within the copy of your website.

You will need to use the exact words that are being used in a search. SEO is not about deceiving the search engines by using words that are not related to your site. Also using too many keywords is also detrimental. You must make your copy compelling and readable – not only for the search engines but your visitors as well.

Here are a few tips that can help you advance your site’s ranking:

–Place within your copy good keywords that are about your content as well as be relevant to the phrases people will use in their search.

–Write and use well-written, original, compelling copy that will provide value to your site visitors.

–Ensure that each page of your site is different; each should have its own title and topic in addition to page-specific keywords and original content.

–Link to sites outside of yours that may deliver similar copy and encourage sites to provide reciprocal links.

–Optimize to your visitors first, then the search engines.

Have you heard the term “supercomputer”? Currently these types of computers are considered to be at the front of the class in terms of capacity and speed.

Introduced in the 1960s, the first supercomputers were developed by Seymour Cray and Control Data Corporation. In the 70s Cray left Control Data to form Cray Research and subsequently was the leader in supercomputer development from 1985 to 1990. Other supercomputer competitors entered the market during the 80s, until the 1990s “supercomputer market crash.”

In today’s market, supercomputers are usually custom, one-of-a-kind products. Companies that are producing these specialties include IBM, Hewlett-Packard and Cray. Currently the fastest computer is considered to be the Cray Jaguar.

Because supercomputers have custom CPUs and pioneering designs, their design gives them the speed advantage over traditional computers. They have the ability to perform tasks in parallel. They are generally specialized for certain tasks, and interestingly many of these supercomputers cannot perform general computing tasks in a satisfactory manner. Memory hierarchy also allows these types of computers to perform at a higher rate. The I/O systems also support higher bandwidths and thus, latency becomes almost a non-issue during computations. One problem that the supercomputer does have is that it creates huge amounts of heat and requires industrial-strength HVAC cooling apparatus.

Because of the speed in the progression and development of computing platforms, present-day supercomputers are likely to be tomorrow’s regular computer.

What Are Supercomputers Used For?
These speedy computers are now used for calculation-intensive duties. These include problems from the fields of weather forecasting, quantum physics, biological macromolecules, molecular modeling and physical simulations. One interesting use is a certain classification of problems known as the Grand Challenge. These problems require full solutions that have a requirement of almost-infinite resources of computing. Examples of Grand Challenge problems include electronic structure calculations, computational fluid dynamics, plasma dynamics and similar functions.

This old print trick should also be embraced when thinking about the design of your website. All the really cool, eye-catching should be placed at the top of the page. Don’t use this space for graphics or ads that will force your visitors to scroll down.

Here are a few more great design tips to help you create a compelling website:

Remember that “less is more”. Studies prove that a website has a mere few seconds to draw a visitor in and compel them to stay there. Don’t present overly done-up pages that take an eternity to load. Your visitors will go away quite quickly. And don’t forget that not everyone has a blazingly fast connection. Design your site to load well at the lowest connection speed. Make sure that all your graphics have been properly optimized. And take a good hard look at those graphics: Do they really enhance the site or are you just including them because they are “cool” or you just learned a new program and you want to show off? All the dancing bears can distract your visitors, when in actuality all they want is information.

Consistency is a good thing. Make sure your navigation remains consistent so people can easily move around your site without have to relearn your navigation on each page. Navigation and menus are usually found at the top or along the side. If you get too creative you may make your visitors uncomfortable. The same goes for links — makes sure you use a consistent color scheme.

We have all visited or experienced websites that literally make our eyes spin around in our heads or perhaps may even give us a headache. More often that not this reaction is cause by poor color choices. It could be opposing colors, clashing colors or just way too many colors in general.

Many people who have decided to build their own websites, find themselves somewhat fearful of color choices. It seems that there is an infinite number of colors out there from which to choose. But think of it this way: everyday you choose colors for your day’s outfit, and you probably chose the color to paint the rooms of your house. You’ll be fine with just a little knowledge and guidance in choosing colors for your websites.

Remember that color causes emotional responses in people, so make sure you select colors that represent your content. For instance if you have a website for children you will want to use colors that are saturated and bright. For instance yellow evokes feelings of happiness and sunshine.

Basic Color Schemes
Websites using the monochromatic color scale use the primary colors as a foundation. Then shades of these primary colors are used as an enhancement. This type of color is considered to be soothing.

Adjacent colors on the color wheel are used in the analogous color scheme. The chose primary color remains dominant in the site while the others are used as a highlighting tool. This color scheme is like the monochromatic one but has more vibrancy.

Colors that are on the opposite side of the color wheel from each other are considered complementary. There are two colors that are generally used in the format; one being more dominant and the other is an accent color. Websites using this complementary color scheme have a high-contrast effect.

Security is at an all-time high on the list of things that businesses and individuals want for their computer systems. Many are willing to spend the money or access the necessary resources they need to protect their investments. For businesses that do not have or cannot access file recovery systems, making sure that the initial protection is there is very important.

For instance, in social media monitoring situations, it’s important to know what kind of information is being shared on that platform and in what methods the information is being transferred. People often have a tendency to join many different forums and/or groups and lose track of where they’ve left their information and how much of it is there.

Securing the information that is shared online is often a matter of utilizing certain software applications and customizing it to fit the individual’s or the business’s needs. In many online situations where privacy is important, there should also be secure systems in order to protect the user and her personal information further.

Users can implement software applications like spyware, anti-virus software, and firewall applications to guard against intentional breaches in their security system or those that were purposefully hacked. There can even be special software written or designed that will store information away securely or mask it inside of computer files.

With all the options available, there’s no reason for you not to secure your important data.

You have determined that you want to build your very own website. Now think about the really bad sites you’ve experienced. You know the ones. Lots of opposing colors, twirling shapes and no logical navigation. We’ll get to that soon enough.

Keep in mind that creating a website design plan is essential and perhaps the most important step in the building of your website. It doesn’t matter if you are using a simple website builder or a more high-level program such as Dreamweaver.

Your plan needs to include what content you want and how you wish to present it. A little time working out this plan will help you create a site that your visitors will enjoy. In addition, you need to make sure that your pages load quickly and are easy to navigate.

Think of designing your website as a problem solving experience. Most people are the Internet in search of information and answers. Make sure you have and understand the particular niche you want to communicate.

Clean, elegant design is also a point that you need to consider. Provide information quickly and in a visually appealing format will create the feeling that you want your visitors to keep returning. Don’t make your visitors search for the information or solutions that may be looking for. For example one of the most simplistic websites out there is Google. And think about how simple the design is. Nothing pops up, nothing twirls or makes sounds. It’s simple and direct.

After you have decided on what product, service or solution you will be offering on your site, make a list of how you will or can deliver those things. You can actually make that a “mission statement” of sorts. Make sure that your website stays focused on the delivery of those solutions, and you will find yourself with a great website.

Unfortunately, email is usually the way a user’s computer gets infect. With this in mind unless you are absolutely, positively sure you know the sender and you trust him or her, never click on a link or attachment. Why you ask? Well many virus are spread using emails that appear to come from your friend, however your friend’s computer is probably infected and automatically sent out the email and virus, unbeknownst to your friend. These messages will usually have a neutral message such as “click here for information.”

Other types of infected emails may also appear to be sent from your bank or another company you know. These emails are usually malicious code that was gleaned from your browser usage. Keep in mind that most legitimate businesses do not send unsolicited emails.

If you get a pop-up message about some disaster in your area, under no circumstances should you open the link. Hackers use location information to create these message and once you click on it, you are almost instantly infected.

Another tip which most of don’t think twice about is using disks and thumb drives to share information. This is one of the most prevalent ways that viruses can get passed from user to user. Makes sure that the disk or drive is scanned before accessing it.

And do not ever download software from unknown sites. Make sure it is a reputable site that you know and trust.

We’ve all heard about computer viruses and some of us may have been infected. Viruses are on the rise across the Internet. Just recently a virus that affects Macs has been discovered. In the past Macs where generally considered immune to viruses. This proves that viruses are becoming more and more widespread.

Not only can viruses destroy your computer but also they can steal your identity and other such dangers. We all need to learn to protect ourselves. We insure our cars and our homes, so it’s logically that we would want that same protection for our computers.

You should first realize the importance of your computer in your daily life. You probably do many things via the Internet such as accessing your bank account, pay bills, access email and so on. Unfortunately these activities do put your computer at risk. You don’t need to stop these activities, just protect your computer.

One tip for safe computing and to reduce your risk of getting a virus is to not download anything from a site that you do not know. If someone you do not know sends you an email with an attachment, don’t open it. If you use or share disks or memory sticks make sure that they are not infected with a virus.

Get an anti-virus program and keep it up to date. Configure it to scan your computer automatically. However, not all anti-virus programs are created equal. And some anti-virus programs out there are actually viruses hidden in anti-virus packages. Do some research before you install one of these programs.

Also, make sure that your operating system has the latest update installed. Operating system updates provided by software manufacturers usually include security updates. These security updates can patch or repair any risks within the software. Many software providers have these updates available automatically.

You’ve just logged into your email and there they are. All those unwanted messages that take up your time to delete. You think, “What if I accidentally delete an important email?” or “Why the heck am I getting all this spam?”

Spam is basically the electronic version of junk mail. Just about everyone these days has seen a rise in spam and it is quite the nuisance. And it is only getting worse. According to Earthlink there has been a nearly 500 percent increase in the number of spam messages during the last year or two. Software vendor Brightmail says that almost 45 percent of email messages is considered spam.

You may have heard that there are laws in place to prevent spam; however don’t hold your breath that you won’t be getting spam anytime soon. But there are things you can do to help prevent receipt of spam in your mail box.

–Don’t post your email address on websites. Studies have found that if your email address is on a website available to the public, you are five times more likely to receive spam.

–If you are running a web-based business and need to provide a way for customers to contact you, try the following.
-Use a email form that customers can fill out and send, but that does not contain your email address.
-Create an alternative address that can be used on the website. This way your central address won’t be posted.

–When you visit websites that request your email use that alternate email address.

–Do not use the “unsubscribe” link on unwanted emails. Spammers use this to actually confirm that you did receive the message and that the address is legitimate.

–If possible use an email program that can isolate messages that could be spam.

According the Wikipedia, the largest current registrar is Go Daddy — we’ve all seen the commercials. Melbourne IT and Tucows are also ranked high in size. Interestingly, early registrars such as Network Solutions have been surpassed by its competitors. Network Solutions was once the sole provider of domain names available to the public.

Two organizations, Internet Corporation for Assigned Names and Numbers (ICANN) or a ccTLD (country code top-level domain) are responsible for the certification of these registrars.

Registrars are required to follow the rules and actions set down by two domain name registries when setting up and performing domain name. Domain name registries are a directory of domain names that are registered within a top-level domain. The IANA (Internet Assigned Numbers Authority) manages these names.

Until 1999 Network Solutions was the sole provider of registration services for.com, .net and .org domains. Subsequently competition entered the market including NetNames who were developing independent registrar services. In 1996, NetNames introduced a commercial, standalone registration service. Other registrars started a new business model that not only included name registration but other services such as hosting.

October of 1998 saw an agreement enter the market place. This agreement created the shared registration system (SRS). This SRS supported multiple registrars. Interestingly it was competitors of Network Solutions that created pressure upon the system to allow a competitive playing field.

The SRS was officially launched on November 30, 1999 and is currently managed by ICANN. Since that time, more than 500 registrar companies have appeared in the marketplace, providing registration services.

Users now have many domain name registrars from which to choose. Due to the market competition there are many pricing models and options that are available.

In today’s market there are thousands of hosting options and services. It’s up to you and perhaps a consultant or designer to find the hosting solution that will be best for you. In addition you need to protect your site from hosts who may not practice business as ethically as some. Some hosting companies have been known to hold your domain name or site ransom should you want to transfer. They may not give you the correct access without additional hidden charges.

How do you choose the best website host for you? Check out some of these tips:

–Understand what your web design requires? Is this going to be only a personal site visited by only your friends and family? Is the site going to be used as a way to increase or start a business?

–Does the host provide you with your own email with your domain name and website? The email systems should be robust and include features such as virus and spam blockers.

–If you are a novice a site, does the company have site builders or other tools to help you? Ensure that should you want to change hosts that these site builders will let you transfer your site.

–Decide on what type of upload method you want to use such as FTP and choose a host that will provide that service.

Do some research concerning customer service, help and FAQ pages. Read online forums and a little research will make your website building a success.

The intent of the creator of a piece of malware is generally what makes it malware rather than any features. Computer viruses, Trojan horses, spyware and adware fall under the umbrella moniker of malware — generally any software that is considered unwanted or malicious falls into this category.

Symantec published results from a study in 2008 that said that the rate of malware code and other undesirable programs might soon surpass the number of real software applications. Another company F-Secure said that in 2007 the amount of malware created that year was the same number produced for the prior 20 years.

The main way malware is distributed via criminals is through the use of the Internet and email. In some cases malware looks like legitimate software and that it is coming from a true site. Some security applications are calling these programs PUPs or potentially unwanted programs.

Early programs of malware were created only as pranks or experiments and were not meant to cause harm, just to be annoying.

Because of the pervasiveness of malware on the Internet in conjunction with malware protection programs that are generally ineffectual, many businesses have had to rethink operating on the Internet. These businesses have concluded that a good percentage of the clients they need to do business with via the Internet are infected; however they must continue the business relationship.

This has resulted in an emphasis being placed in back-office and IT systems being designed to discover activities that may be malware that exist on their clients’ computers.

Approximately 44 percent of the respondents are concerned that their information that is shared can be used negatively. The next category of the study showed that 21 percent of social media users say that people who exploit privacy settings already have that information anyway.

The study was released shortly after it was discovered that many popular social media apps were sharing users information with third-party companies. These applications were among some of the most popular, including Mafia Wars and Farmville.

Lawyers.com is operated by LexisNexis Martindale Hubble and surveyed 1,000 adult users. Marketing vice president of LexisNexis, Carol Everson stated that the survey shows that the actual behavior of social media users and the concerns over privacy is suffering from a huge disconnect. She goes on to say that even though we are constantly bombarded by the dangers of disclosing personal information on these sites, most Americans are failing to take the appropriate steps to protect themselves.

It may simply been that it is actually difficult to know when too much is actually too much. Of the study respondents, 46 percent said that it was difficult to know what information should be kept private.

The sites themselves are also receiving much of the blame; approximately 76 percent believed that the sites were not protecting users information adequately. And many users have not read the sites terms and conditions

Cluster computing is a type of computing where a group of several computers are linked together, allowing the entire group of computers to behave as if it were a single entity. There are a wide variety of different reasons why people might use cluster computing for various computer tasks. For example, cluster computing combines the computing capability of all the involved computers, helping people who cannot afford a single computer with those capabilities to still be able to take advantage of that level of computing power.

Cluster computing is also used to make sure that a computing system will always be available. It is unknown when this cluster computing concept was first developed, and several different organizations have claimed to have invented it. Some people suggest that cluster computing was probably developed independently by several different people in order to meet their unique computing needs a long time before the technique was ever applied to an industrial setting.

A common application for the cluster computing concept is to host websites such as large-scale websites or top affiliate programs. The cluster distributes the load of the website’s traffic or visitors across a wide range of different computers so that the website can accommodate more visitors at any one single time. Cluster computing is also widely used for the creation of gaming servers when large groups are gaming and want to be able to avoid login problems and issues relating to server lag.

One type of cluster computing is HA or High Availability Cluster Computing, which is used to create a redundant network that all users can access all the time. Fail-safes are generally put in place in case a part of the cluster should happen to break down. There are also load-balancing cluster computers that address large loads of simultaneously incoming requests, coordinating those requests in such a way that both efficiency and usability will be maximized.

Phishing happens when an email is sent out appearing to be from a legitimate contact. It may say it is from a bank, credit card company or some other site that would require sensitive information to access. The email will instruct the user to click a link directly to perform a function, such as preventing the closing of an account. Some will even go so far as to say that there has been a security breech already on an account, and the user needs to go there immediately to fix the problem.

Once the user clicks on the link in the email, they will be taken to a site that looks very much like the legitimate site. There may even be a redirect to the legitimate site, with a popup that comes over requesting the usernames and passwords. The user believes that it is the real site, and logs in – which has then just exposed all of their sensitive information.

In order to protect themselves, users need to be diligent in checking links in emails. When a link is hovered over without being clicked on, it will normally show the true address in the bottom corner of the email client. Some addresses can be very similar, with even just one letter different to confuse people. That is why it is never a good idea to click on a link directly in an email.

If the user is concerned about a problem, they can connect to the internet and type the legitimate web address into the browser. They can log in as they normally would and check if there is a problem. That is seldom the case.

Being careful with emails can prevent identity theft and save the user from potential financial loss.

The term “blog” comes from “weblog”, which is a website that is more interactive than a static HTML site. It is normally maintained by one or more people who have an interest in the topic, making frequent posts which show in backwards chronological order. However, blogs have become much more, and the functionality that they now have continues to bring new developments that increase what a blog can do.

There are many different blogging software platforms to choose from. Three of the most popular are WordPress, Movable Type and Typepad.

WordPress

There are two versions of WordPress – one which is hosted through WordPress.com and the open source software that can be self hosted. WordPress offers many templates and widgets which give the software increased functionality. Many users have gone beyond using WordPress as a simple blog, now using it to create complete websites. It is considered to be more than just blogging software, going so far as being a complete content management system. With a simple one touch installation on many webhosts, and an easy to use interface, WordPress is one of the most popular platforms used by bloggers.

Movable Type

Movable Type has become increasingly popular and offers a great deal of options as well. However, installation can be a bit more difficult and if a user is not comfortable installing and setting up a Perl script on a server, they would likely be better using WordPress or Movable Type’s centrally hosted version, Typepad. There are more and more templates and functions being added all the time for Movable Type. Large businesses and corporations use this blogging software to build feature rich websites and interactive communities.

Typepad

Typepad is the hosted blogging software designed by the creators of Movable Type. It offers many features and has an easy to use interface that allows users of all levels to create stunning sites. It does not require any installation or setup, which some users prefer. There are beautiful designs to choose from, and many other features which help users create cutting edge websites for personal or business use.

The operating system controls how the computer will function when it turns on and boots up. It will manage all of the computer’s resources, serving as the central hub that makes sure all of the hardware and software is getting what they need to function properly. The operating system will be managing how the programs are using memory and how the peripheral devices like a printer or a mouse receive information from the computer.

An operating system makes everything more “uniform” so that when programmers create new software and applications they will know all the details they need to make sure it works on a user’s computer. Everything is consistent, and it will not matter about the kind of computer or memory because the application will work on the operating system the computer uses.

Most operating systems are already preloaded onto a computer when the user buys them, although they can be changed and new systems installed, with the three most popular being Microsoft Windows, Apple Mac OS X and Linux. Each system uses a graphical user interface that users can learn in order to communicate and give commands to their computer.

An operating system is the driving force on a computer, but it isn’t important for people to understand exactly how it works. Users only need to learn how to use the operating system that their computer has installed in order to do the tasks they need their computer to do.

A computer network is simply one or more computers that are connected allowing them to share files, programs and hardware. Instead of needing a different printer, for example, for every computer in a company, they will often be joined in a network to keep costs down and make the work much more cost effective.

There are many ways that a computer can be connected, including cables, satellites, phone lines, radio waves – any way that can connect two units together allowing them to exchange information – can be used. Networking computers have many benefits, including the ease of sharing information via software like ares p2p and hardware, and the reduced cost of needing separate programs and devices.

A network normally has three important components: a server, a workstation and a means of communicating. The server acts as the main computer that allows access to hardware and files from other computers and allows them to perform duties like sharing data and files with programs like aresgalaxy. It is the main computer and provides the service to the others in the network. A workstation is essentially any of the other computers in the network that can be used to access the hardware or software. And, the channel for communication is the path that is used to send information between computers or peripheral devices. These channels can be with cable, or even wireless.

As new workstations are added, the network will grow. These networks are often categorized either into a local area network (LAN) or a wide area network (WAN) depending on the size and area of the network.

In a LAN, the workstations are all connected in a small area, such as a home or small business. Resources are shared between a few computers and perhaps printers and other similar peripheral devices. WAN connect networks in completely different locations. WAN can connect LAN using cables, satellite and wires. Many businesses use WAN to connect when needing more than one geographic location. An example of a WAN would be the Internet.

Networks can help make the most out of smaller budgets, helping users share information and resources.

This is a common occurrence, and it may put your project in jeopardy. Companies who often pair co-workers as teammates may want to consider a better solution: cluster computing. With cluster computing, a company eliminates the issues caused when employees store data on their own hard drives. It does this by setting up a central hard drive for the entire company.

As soon as your co-worker saves the Excel spreadsheet to the hard drive, you can log in on your computer and access the file. If your co-worker is sick, you still have access to the files you need. Plus, anything you save to the hard drive is accessible for your colleagues. That means you can head home at the end of the day and know you won’t get a phone call to email copies of your files.

Other benefits to cluster computing include sharing a common directory, having access to the same programs as everyone else, reducing the need to verify a document from another computer (which can reduce the number of flagged security alerts), and sharing a network.

Cluster computing makes it easier to do other things, as well. Instead of having to search for free download software for each machine, your boss can download and save the program to the hard drive for everyone to access. Boy does that save time!

However, with the increase in online shopping, many people worry about how safe their personal information is when they make a transaction. When you take into account the fact that internet shopping has come a long way in terms of security, and realize that it can be just as dangerous shopping offline, making purchases online really don’t seem as dangerous as many would seem to think.

That doesn’t mean that it is completely safe. Shoppers need to take measures to protect their information when shopping online the same way they would if shopping in a physical store. One of the most important safety measures that need to be taken is making sure that the website is using a connection that is encrypted using a security protocol called Secure Socket Layer (SSL). It is very simple to check for SSL encryption – a user simply has to check the address bar in the browser to check for an https: address instead of the normal http:

The larger shopping sites, such as Amazon or Best Buy have strong security measures in place when storing data. Information is normally very safe when making a transaction through these sites. However, many smaller and less known sites are just as safe and provided they are using secure encryption during their checkout process, shoppers should not need to worry.

Making sure that computers are free of spyware and that website addresses are never clicked directly in an email to go shopping are other safety measures users can employ. Online shopping can be just as safe as offline when users take the proper safety precautions.

Freeware

Freeware is often confused with open source, however there are some major differences that should be noted. Freeware is essentially free to download, use and distribute, provided it is an exact copy of the software. The user does not have access to the source code, meaning they cannot modify it in any way, and the original programmer still maintains the copyright. There is normally no way to update or offer support to the users of the software.

Shareware

Shareware also has a copyright, and is allowed to be downloaded and used only as a trial basis. The concept behind shareware is to let a user try the software before purchasing, but there is normally a set time limit that it can be used before having to pay, or limited functionality until the full version is purchased. The user does not have access to the source code, and no modifications can be made. In the case of shareware, it is up to the developer to offer support and updates for the software users.

Open Source

The source code in open source software like open office and FileZilla is available to everyone. It can be modified, used and the source code can be re-distributed to other developers and users. Most of the time, the software is free, which is sometimes where the confusion between freeware and open source can come from. However, it is possible that some open source applications are not free, but the source code may be. There is usually a large support community with an open source project, and frequent updates and modifications by members, which means that the user is not dependant on just one developer.

It can be confusing when trying to understand the different software options, but it is important to know usage rights before downloading and using a software program.

Microsoft Windows

Microsoft Windows is likely one of the most recognized computer operating systems among users. It has been suggested that more than ninety percent of computers have a version of windows operating system installed. There is a home version for personal use or a professional one for businesses. Windows is the operating system that most computers come preloaded with, but it can also be purchased on its own for those who do not have it on their computer.

Apple Mac OS

The Mac OS is the line of operating systems created by Apple to be used on their Macintosh (Mac) computer. Although not as popular as Windows, only accounting for just over seven percent of the market, Mac users are very loyal and the number of users are continuously growing. There is also a home version for personal users as well as the professional version.

Linux

Compared to the other two operating systems, Linux only has about a one percent share of the market. However, it is a viable option for users who are looking for a good operating system that does not cost a fortune. Linux is a free, open source program that allows the software to be downloaded and used by anyone, and the source code is also made available. Any developer or company can take the Linux kernel and add to or modify it however they want. Many businesses are using Linux due to the functionality that can be added and how flexible it is to use.

There are many more operating systems on the market, and each has its advantages and disadvantages, as well as their own group of supporters. Depending on what it is needed for, there is an operating system that will meet the needs of any computer user.

There are different methods a user can follow to make a backup, and the best one for each will depend on many factors. External hard drive storage and online backup services are two of the most popular methods.

An external hard drive will connect to a user’s computer and the data and files will be backed up onto the hard drive. A hard drive will cost a bit more money upfront, depending on the size of memory needed. This may be an option for those who are more adept with computers and who will be able to remember to make a backup regularly. Another thing to remember is to store the hard drive somewhere away from the computer that is backed up because if there is a fire or other disaster, all of the information would be lost anyway.

Many people are turning to online backup services due to their ease of use and features. The backed up files and information are stored online away from the computer itself, which makes all of the data safe from any possible loss. Even if there is something as devastating as a fire, all of the information from the computer is safe online. Most of these services are set up to do scheduled backups as often as needed without the user needing to remember to do the backup themselves. They can be set up to do a backup overnight when a user does not need the computer, and it will back up any new files it finds on the computer.

Depending on skill level and needs, each option can save important information in the case of computer loss.

Password Security
When creating a password for any website online, it is very important to not use one that is simple to figure out. For example, using children’s names, or anything else that is easy to identify is never a good idea. Creating passwords that are difficult to crack, using capitals, lowercase, numbers and symbols will make it almost impossible for cyber-thieves to decipher. Keeping a notebook with all important passwords written down will prevent any confusion when needing it in the future. Or, using a program like Roboform which securely stores all passwords, can keep all information safe and easily accessible.

Working on Public Computers
Using computers in public places like the library or internet cafes can make sensitive information easier for thieves to access. Computer caches will store information about each site that is being viewed, making it visible to anyone who logs on after. While this helps to speed browsing on a private computer, it also allows for easy tracking on public ones. To clear the cache, click on the “Preferences” or “Tools” tab on the internet browser, and choose to “Empty Cache” or “Clear Recent History”. Each browser will be slightly different, but following the prompts will clear any sensitive information before logging off a public computer.

Giving Credit Card Information Online
Before giving credit card numbers for online purchases, the easiest way to be sure the site is secure is to look at the web address in the browser. If it begins with “https:” instead of the regular “http:”, then that site is using a secure, encrypted connection to protect against third-party viewing.

These are just some of the ways of securing information online. Taking some time to secure sensitive information can prevent a great deal of trouble down the road.

Cluster computing, in its simplest definition, is taking two or more computers and linking them together to work as one. By combining the power of each computer, the result is a much more powerful computer that can keep up with the demands of changing technology.

The reasons for cluster computing are many, including cost reduction. For businesses and companies that have less money to put towards soaring IT costs, having a cluster network of computers can be a much better way of spending resources. In order to afford the processing power provided by the network of computers working together in one powerful unit, businesses would have to spend much more of their budget than combining the power of the computers together.

In addition to the costs, these cluster computers provide a great deal of power when put together. Because single computers have a more difficult time keeping up with the changing needs of hardware, a cluster is better able to handle more complex applications.

Another reason for cluster computing is the need for a system that is more reliable and will not fail. A common use for these clusters would be website hosting. A cluster will spread visitors over all the computers in the cluster in order to spread the load between them. This will prevent an overload, causing a crash that could bring the system down. The computer cluster ensures that the system is always available, which is not possible with a single computer system.

With the advances in technology, cluster computing is allowing businesses to harness the most power from their computers, without having to spend a lot of money on expensive systems. As systems and applications evolve, a single computer just cannot keep up with the changes, which is what makes these clusters so desirable for businesses and companies who are keeping an eye on their budgets.

Computer clustering offers a much more powerful system with a great deal of benefit to its users. The reduced costs of a powerful network of computers that are able to keep up with changing technologies appeal to many businesses which need a reliable system. There are different types of computer clusters, with each offering specific benefits. It is important to understand the differences in order to get a system that works best for what is needed by the end user. Among them are:

Load Balancing Clusters
These types of clusters work by taking information into one or more load balancing computers, which are called nodes, in the front, and dividing the workload evenly by spreading it out between the remaining nodes in the cluster. By distributing this work equally, it harnesses the limited processing power into a more powerful system. The load balancing cluster is designed to always be working, however if one node fails, the cluster will not work.

High Performance Clusters
High performance clusters are specifically designed to combine the processing power of parallel computers. These clusters are most common for applications that require one computer to be able to communicate with another in the cluster while performing its tasks. Often the results of one computer task will directly affect the future results of another in the cluster.

High Availability Clusters
When access is needed at all times to server applications, high availability clusters are used. They are designed to maintain nodes for backup systems in the case of a failure. The minimum amount of computers, or nodes, in one of these clusters is two. One is the active node, while the other is redundant and used in case of a backup. However, most high availability clusters have much more than just the minimum amount of computers. These HA clusters ensure continuous access to computer power, which is especially important for a business that relies on data processing that is time sensitive.

Cluster computing offers a lot of benefit to users who need to maximize power and efficiency, without extra costs.

Browser

An internet browser is the software application used to retrieve information from the web, allowing the viewer to see the pages and documents available online. It translates the HTML encoded information for the user. Most browsers will have different features, among them a back and forward button to let the viewer easily go back to a page they already looked at; a stop button to cancel the retrieval of a page; a home button that allows for quick return to the users home page; an address bar where complete web addresses can be typed for direct access; and a search bar where the user can type what they are looking for and be presented with a variety of sites to choose from. Some of the most common browsers are Internet Explorer, Firefox, Safari, and Google Chrome.

Cache

A browser has what is called a “cache” which is a space that stores previously visited sites onto the computer. When needing to go back to a document or site that has already been viewed, the browser will check if it is stored in the cache first. If so, it will retrieve it from there as it requires much less time to bring it back up than going back to the server.

Bookmark

Web browsers all contain a way to save favorite links that can be easily retrieved without having to remember the web address. In order to save a web page into bookmarks or favorites, the browser will have a tab to click bringing up a box which allows the page to be saved to a folder. The next time the visitor wants to visit that site, they simply click on the bookmarks tab then scroll to where they saved the link.

These are just a few basic terms that can help ease some of the confusion of the internet.

Server

A web server is essentially a host computer that serves up the web pages that are being requested through a user’s browser. When a web address is typed in to the address bar of a browser, the server retrieves that page from the web and presents it to the computer that is requesting it.

Cookies

The simplest definition of a cookie is a message that is passed from a website’s server and placed on a user’s computer hard drive or browser. There has been a great deal of publicity about cookies and privacy issues, however these pieces of information are generally used by a website in order to make the browsing experience more enjoyable. Cookies will tell a website if the viewer has been to the site before, and remember their preferences. Some cookies will expire on their own, meaning that if the visitor does not return within a set amount of time, they will appear as a new visitor. Others will remain unless they are manually cleared, so that the visitor will always be seen as a returning visitor.

Surf the Net

Surfing the net really does not require any special skills, and most importantly, no special wet suits or gear. Basically, surfing the net is much like flipping through channels on a television. When a user connects to the internet with their browser, they can type in an address or search term that will bring up a website. As the user goes from one site to another, this is what surfing the net means.

These are just some of the many terms that will be heard when using the internet. Understanding what they really mean can ease some of the confusion for many users

With the unbelievable speed that the internet is growing, seeing thousands of new pages and documents being added to the World Wide Web every day, it can be a huge challenge to find information that is relevant to what a user is searching for.

That is the problem internet search engines were designed to tackle. A search engine is a special website that is designed to help users find information on the internet. It compiles data from websites all over the internet, and stores the information in an index that allows it to be retrieved when a specific key phrase or term is typed in by a user.

In order to find and index all of these sites, a software robot referred to as a spider, is sent out to build lists from all the words found on a site. These robots travel to more pages and sites through links found on other websites, taking it all over the internet indexing information, and returning to look for new content.

The spiders will take note of information on a page, and compile lists of words that are dominant on a page in order to assess the purpose its purpose. Each search engine has different algorithms that their spiders follow when retrieving words on a page. Some will put emphasis on meta tags, while others will look for recurring words in titles and throughout the page. The job of finding these sites all over the internet and indexing them to be found is a monumental task, and one that is never finished.

When a user goes to Google, Yahoo or any of the many other search engines, they will type in a search string related to what they are searching for. The search engine will go back into its index and retrieve the websites that are most relevant and display them in order of how important they believe the sites to be in regards to what is being searched for.

While it is very difficult to index every site, search engines are making navigating the internet for information much easier every day.

Computer viruses are a real concern for anyone who has a computer connected to the internet. No one is immune to a virus attack, whether it is a large corporation or a small personal computer at home. Viruses can spread quickly and cause major damage to infected files and computers.

A virus is a manmade program that hides and then replicates or copies itself onto other programs on the user’s computer. It isn’t the replicating that causes a problem on the computer, but the fact that each virus can be programmed to do certain tasks, such as delete certain files, corrupt programs or overwrite something on the hard drive that making it inaccessible. It can cause a computer function poorly, and can take over an entire email system that sends out the virus in emails to everyone on the contact list.

Some viruses will hide on a computer until a certain scheduled time, or may act immediately. They may act only when the specific file is being used, or can continue attacking at all times. Even the simplest viruses can cause problems by taking up space and memory, causing computers to slow down and even stop working.

Viruses can spread through attachments on emails, or when downloading an unknown file from the internet. They are designed to replicate and spread quickly, causing as much damage to as many computers as possible.

While it is almost impossible to protect a computer from a virus, there are steps that can be taken to keep it safer. Files should only be downloaded from places that the user are familiar with and secure, although even that isn’t foolproof. Email attachments should never be opened unless the sender is well known and the attachment is expected by the user. Using a good virus protection program is a must, and backups should be frequently made on the computer in case of any problems.

Viruses will keep getting more advanced, but doing all that is possible to secure a computer can help prevent the further spread and destruction of these manmade attacks.

In order to understand it better, it is important to make it clear that spyware is not the same as a virus, and in truth, is not the same as adware or malware, although it is often lumped together or used interchangeably with those terms. Because of the confusion between all of these definitions, it can be difficult to even know what to call it.

Spyware, in its simplest definition, is a rogue application that is installed on a user’s computer meant to collect personal information. It is most often done without the user knowing, except in the case of keylogger software that can be installed by an owner of a public or shared computer that will monitor the usage of others.

Most of the time, this information is sent back to a central server and used for marketing purposes. Distributors claim that the information is gathered to create better products and services to their clients. But, there are still many opponents to spyware who state that it is an invasion of privacy.

In addition, some spyware can cause more problems for the computer user, such as taking over the Web browser and redirecting to other sites, or slowing a computer down to a crawl. Other problems that can be encountered include changing computer settings and causing the loss of other Internet or computer functions.

Spyware is often installed on a user’s computer by piggybacking on software that they are already installing. Other methods of infection include tricking the user into believing it is something else, known as the Trojan horse method and often disguised as security software, or by searching for holes in the Internet browser to sneak in.

Thankfully, there are now many anti-spyware software programs which can help detect and get rid of the unwanted spyware on a user’s computer.

Spyware is normally installed on a user’s computer without their knowledge. It can remain hidden for a long time before the person notices that something isn’t quite right with their computer. There are some common signs that can be watched for to let the user know there is a problem.

New homepage setting – If a user notices that their homepage has been changed, it is likely that there is spyware installed in the background. Often, when the user tries to set it back to the original page, it will reset to the new one again.

New toolbar – A common symptom is having a new toolbar installed on the browser.

Unknown advertising popups – Spyware can cause unexpected popups to come onto the screen, even when the user is not searching on the internet. Often, the popups are difficult, if not impossible, to close.

Sluggish computer- Spyware can use massive amounts of resources, often slowing a computer right down. Sometimes a user may notice that tasks are taking two to three times as long as normal.

Unknown shortcuts -Desktop shortcut icons may appear that were not previously there, indicating that spyware is involved.

Error messages – Unknown error messages that keep popping up for something the user does not remember installing is often a clue to spyware.

Hard drive working overtime – Spyware can be working in the background, even when the user is not working on the computer. If they notice it making noise as though it is working for no reason, it can indicate that something is working behind the scenes.

New favorites -Spyware can save favorites that the user does not remember saving.

Firewall alerts – When alerts appear that an unknown program is trying to access the internet when the user is not, then it shows that something has already got onto the computer, and is now trying to get back through to the internet.

Although many of these problems can be symptoms of other issues, when two or more show up together, it is likely that spyware has infected the computer.

Searching the internet can sometimes be as difficult as finding that needle in a haystack. In other words, finding a good website relevant to what the user is searching for can be a challenge. There are some tricks that can be used to help search engines bring back the best results.

Keywords

Entering all relevant keywords will help to bring back websites that contain those words. More keywords in the search bar will narrow the results. For example, the keywords “truck for sale” would not be the best keywords to use as they would bring back millions of results that would not be needed. However, typing “truck for sale new york” would be much more targeted.

Using Quotations

Typing the keywords inside quotations will bring back only the results that have all of those keywords exactly as written. This can bring back much more relevant results.

Leave Out Unnecessary Words

When typing a query into a search engine, words like”a”, “the”, “in” and others that are similar, do not need to be included. It is best to use only the main keywords, and in fact, some search engines will ignore those words anyway. For example, in the case of “hotels orlando”, it does not need to have the “in” added. It will just slow down the results, and sometimes cause unrelated results.

Using Advanced Search

Most search engines, such as Google, Yahoo and Bing will have an option to allow for an advanced search. Yet, there are not many people who take advantage of this feature, which can bring back much more relevant results.

Boolean Basics

Some search engines make use of what are called Boolean commands, which are the words”AND”, “OR” and “NOT”. Putting these commands along with the keywords will filter and bring back the closest results possible. For example, putting “red purse”AND “free shipping”, the results will only show the sites that have those two sets of terms. The other commands work the same way.

Learning to search the internet more effectively can ease some of the search engine frustration that many users experience.

Cluster computing can be very advantageous, especially to a big company. Because all traffic is routed to one “location,” there is little if any delay because a particular server or other routing system is overloaded or even offline. With cluster computing, the main system takes the information and analyses it to see if it would be better served by being routed to a less busy or alternative server. The information will still be available no matter where it comes from, but it will certainly get there faster.

The main drawback to cluster computing, however, is that you can see what everyone else is doing, including what files they are in, what information they are accessing, and so forth. And they can see you too. This not only includes the people right there in the office with you, like the boss, but anyone who is connected to that cluster computing system regardless of location.

In other words, if you are trying to sneak in a few rounds in one of your favorite online casino games, everybody’s going to know it. Now, if company policy allows this on your regularly scheduled break times or free times, then there may be no problem there.

One problems can come from doing activities that aren’t allowed. Since everybody can see you, you are going to get caught.  Additionally, if you are accessing a site that requires you to give out personal information, such as bank account or credit card numbers, as many online gaming sites do, you may have no control over who else can see that information.

Firewall

Firewall software works as a barrier between offensive sites and destructive viruses or hackers and a computer network. It essentially works the same as a physical firewall that is designed to prevent the spread of fire in a building, except in this case it stops the spread of unwanted problems and personal information. Firewall will be placed at every possible opening that needs to be protected from the outside world, preventing any unwanted forces from gaining access.

Antivirus Software

Antivirus software is one of the most important programs to be installed on a computer that will be accessing the internet. It acts as a defense against viruses and other malicious programs that try to get onto a user’s computer. In addition, because there are always new threats and viruses being sent out, it will also scan and identify any threats that may have made it through all the lines of defense.

However, antivirus software will only work if used properly. The software manufacturer will often send out updates whenever a new virus is identified online, which requires the user to check and update their software immediately. Scanning the computer frequently is also important to ensure that nothing has found a way through all the barriers that are in place.

Anti-Spyware Programs

With the increasing amount of spyware and other malware, installing anti-spyware software is becoming much more important. There are more being created every day, and as with the antivirus software, it is important to keep them updated and do frequent scans of the computer.

Many of these software programs will tackle multiple tasks, and may offer all three areas of protection. There are free versions available online, and it is important for the user to research and understand which will be the best solution for their own needs.

Opening Attachments
Never open an attachment that has come in an email unless the sender is well known and the attachment is expected. Viruses and malicious programs can hide in attachments on an email and infect a user’s computer as soon as it is opened. Since email can be the target of hackers and viruses, it is important to be sure that the message has really been sent from the person it states, as a virus can infect a computer and send emails out to everyone on their contact list. If the message does not seem like something the contact would send, just delete the email or get in touch with the person to be sure that they did send the email.

Clicking on Links

When an email comes in that instructs the user to click on a link, it is always advisable to just go directly to the internet and type the site address into the browser. Sometimes, an email will come in that states it is from someone who it actually has no affiliation with at all. When the user hovers over the link in the email without clicking on it, it will bring up the actual address that that link is directed to. This is a common tactic used to get sensitive information because when the user clicks on the link directly, it will take them to another site that may or may not look like the real one. If the user needs to log in with a password, it will record that information and be able to use it. These emails often say something about being from the user’s bank or credit card company, and they need them to log in to check on security or some other “problem”.

Being careful while reading and opening emails can prevent a host of future problems with both sensitive information, and the user’s computer itself.

Encyclopedias were the “to go” to source of information before the advent of the Internet. They contained information on almost every possible topic imaginable.

The need for an online encyclopedia became quickly apparent as the Internet grew at a rapid pace. The Internet became flooded with information of all types, some more reliable than others. There needed to be a single location to consolidate all “encyclopedic” information, while at the same time have the information reviewed for accuracy. This need created the genesis of Wikipedia.

Wikipedia is the largest online repository of reference work in the world. Creators Jimmy Wales and Larry Sanger launched the website in 2001 and it quickly became one of the Internet’s most visited sites. Wikipedia exists on the principles of crowd sourcing where anyone can contribute to any given topic. Fact checkers verify the information adding to the reliability of the information.

Many of the criticisms of Wikipedia derive from the very fact that it is crowd sourced. Critics state that the information on Wikipedia contains many inaccuracies and biases, despite its peer review system. Other criticisms include poor quality of writing.

Despite the critics, Wikipedia continues to grow (as of 2010). Wikipedia is now published in several different languages and has a foundation built around it. Wikipedia is a perfect example of what many people call the “democratization of knowledge,” where anyone can access any piece of information at any time.

Video games got its start before the mass distribution of personal computers. Missile defense systems of the 1940s provided an environment for the first forms of video games. By the 1950s other, less complex, games were developed. More games were developed as technology improved. Games were primarily programmed on mainframe computers but were latter expanded to classic arcade and console based systems.

The first video game that had commercial success was Computer Science. This game created the groundwork for the gaming industry. Much of the gaming development from that point was done in the United States and Japan – which are now homes to the largest gaming companies in the world.

The 1970s is considered by many as the “Golden age” of video games. This decade spawned many of the classics such as Pac-Man and Space Invaders. Atari also got its start during this decade. Atari is responsible for many of the famous home console games such as Pong. Arcade cabinets and dedicated arcade stores started to pop up on shopping malls and restaurants across the world.

Commercially available home computers further drove the development of computer games. Source codes of games were made available for the ambitious and owners of computers could program games into computers themselves.

The 1980s continued to generate great software and new hardware to power games. Home systems such as Intellivision and ColecoVision were big hits. Aside from these great systems – modern day gaming was defined by the 1985 release of the Nintendo Entertainment System. Nintendo became a huge success and quickly catalyzed the development for more game programmers.

Since Nintento’s release many gaming manufacturers have come and gone – each advancing the gaming industry. Gaming software and hardware continues to evolve and it is exciting to think about how games will be in the future.

As any nerd could tell you, clustering any group of computers basically allows them to function as one cohesive unit. In cases such as a wireless network, a group of clustered computers basically allow the system to function even if one or more of the components within the group fail. Since wireless customers like to have their service available 24/7, this is a very important part of the success of clustering. When one point of failure doesn’t bring down the entire system, the people who depend on you can rest easy. But reliability is not the only benefit of having clustered computers hooked up.

When your network is clustered properly, you have more than just a reliable group of computers. You essentially have one very large, very powerful computer that you can use to perform a wide range of tasks. If you require a great deal of computational power, such as for plotting the wind patterns inside of a tornado, you can use the processors of each computer as fluidly as if they were part of one machine. This is a great efficiency, and allows you to rock functions you never even dreamed of.

MMORPG’s enabled users to create a new character online and lead a complete life. These games emulated or created a new world for players to live in. Houses could be built, professions chosen and even virtual marriages are performed. These games would charge its players a monthly fee to access these servers that hosted these virtual worlds.

Client servers are used to host these worlds. These servers are setup to maintain a constant environment “live” on the Internet. Each game comes with software that allows players to access these worlds.

Most of the successful MMORPGs were based on fantasy worlds. Games such as World of Warcraft are built on the fantasy world of the famous computer game of the same name. Players could role-play using characters from that world. Players could join forces and complete missions to gain experience and progress in that world.

Progressing in ones world is essentially the goal of each MMORPG. Experience points are rewarded as a player accomplishes certain tasks and obtains new skills. Capabilities increase as more experience points are accumulated.

Of course much of the popularity of MMORPGs is the social interaction you gain from playing these games. Players can make new friends online and share their common interests using these games as a vehicle. The reality of these games has been so “real” to some people that jobs have been lost and marriages broken because of it.
MMORPG’s popularity will increase as more areas of the world gain access to the Internet. A few games have also started to offer games without a subscription fee. Technological advances will make these games even more “real.”

Many people purchase desktops and laptops out of a necessity to do some sort of word processing. Whether it’s companies needing workstations to publish documents or a college student to write term papers, a large number of computers are sold for word processing purposes.

Word processing is so common that many computers are sold with a solution preinstalled. Many college campuses sell laptops packaged with a word processing program. The most common application is Microsoft’s Word. Word has an extremely large user base. It was one of the first word processing applications that were sold to a broad market.

Of course one of the most disliked aspects of word processing applications is the cost. Fortunately the Internet has provided fertile ground for programmers to develop other, cheaper word processing solutions. Most of these online word processors are free to use and yet have many of the features of the traditional word processing apps such as Word.

A fairly popular website to get free software for word processing is openoffice.org. This site offers a free program called openoffice which is open source and has gained enough attention that Sun Microsystems acquired it in 1999. It is a great option for those who do not want to spend money on software and still have a fairly robust word processor.

Google Documents is another, free, solution for those unwilling to dish out cash for a word processor. A great benefit of Google docs is the ability to save documents online, thus giving the writer access to their work anywhere they have Internet access.

Technology and the Internet have definitely made our lives much easier. It has also made our live more economical with innovations such as Open Office and Google Docs.

The Internet is simply a complex system of connected computers. These computers communicate with each other using protocol, often referred to as TCP/IP. Computers communicate simple packets of data that are translated using browsers or other web applications such as email.

Media has changed drastically as the Internet has developed over the years. Traditional media such as newspapers, new broadcasts and magazines have lost customers as more and more people are moving toward the Internet to get their news and entertainment. This trend has increased so much that many magazines and newspapers have actually discontinued their printing operations and have focused on Internet publishing. Broadcast television companies have also seen consumers move to the Internet to view their favorite television shows.

Other forms of communication have also changed due to the Internet. Telephone technology has drastically changed with the advent of VOIP (voice over internet protocol). Many households and businesses have completely switched off of traditional phone lines and use Internet communication for their telephone needs. Services such as Skype have also given consumers other options to call friends and family over the Internet.

Each day technology is enabling humans to accomplish much of their day-to-day activities on to the Internet. Developers have created ways for individuals to manage not only their email – but their calendar, contacts and documents all online. Social networks have enabled users to keep connected with friends and family.

IT needs for companies have grown as technology and innovation have improved. Generation and collection of data have increased exponentially creating both a blessing and a curse for many businesses. The processing power needed to filter such large amounts of data often exceeds capabilities of most networks of companies.

Cluster computing enables companies to increase the processing capabilities of already existing computers within a network. Clusters work on the basic principle of load sharing, where processing tasks are spread across multiple computers. Combining the processors of multiple computers allows tasks to be completed at a much quicker rate. What could take many hours for a single computer could be cut down to an hour.

There are many different types of cluster configurations. What type of implementation varies with the specific needs of each user.

HA (high availability) clusters, are created with 100% access to applications in mind. HA clusters are structured with multiple nodes of redundancy, ensuring that processes never fail. These redundancies act as an ongoing backup of the system. These clusters are usually implemented in environments where downtime should be held to a minimum.

Load balancing clusters does exactly what the name implies. A few computers take tasks and distribute them to the remaining nodes on the network. Routing loads through just one or more nodes on the front end optimizes processing power across the cluster.

HPC, clusters and compute clusters are a few other examples of cluster computing that are commonly used in the world. Both have variations on how nodes communicate with each other during computations.

Cluster computing offers many benefits over traditional mainframe computing. Price is usually cited as the top benefit, as relatively cheap desktop computers are only needed to create a cluster. Clusters are also scalable, allowing companies to expand as needed. Redundancy or availability is another benefit.
Cluster computing is a great option for those looking to save money or expand their IT capabilities.

Sitting in your office, your cell phone rings. You pick up your myTouch and have a casual phone conversation. It happens every day in businesses around the globe. However, while you’re talking on the phone and filing office reports, there’s a force working behind the scenes to help you accomplish the tasks you need.

Cluster computing basically takes several different computers, a cluster, and helps them operate like one computer. The most common way to accomplish this is through a Local Area Network. This means that Computer A in Susie’s office can access the same resources and files as Computer B in Bob’s office. When the two computers are on the same Local Area Network, any and all information shared on the network is available for computers to access.

What does this mean for your business?

This means that each computer no longer needs its own printer. A larger printer, accessed through the Local Area Network, can meet the needs of all the computers in the office. It does mean that employees have to get up from their chairs to retrieve the printed documents, but a little exercise never hurt anyone. The same theory applies to scanners, fax machines and other office equipment; employees are able to share.

Another benefit of cluster computing is shared resources. Documents don’t have to be emailed back and forth between employees because everyone can access the same documents through the Local Area Network. There are some safeguards in place, so two people usually can’t alter the same information at the same time, but a little communication with each other can easily resolve those issues.

Cluster computing also improves the speed and availability of each computer. Because resources are stored on the Local Area Network, the computer has more space free on the hard drive. That means the computer runs faster and employees can work more efficiently.
