Fundamentals and Risks of Computer Spyware

By: ramen swarly

In layman's term, computer "spyware" can simply be defined as a legitimate but annoying programs that has been installed on the user's computers with or without their consent. Since the idea of spyware is simply to fetch information, computer spyware exists because of the idea that information has value. Usually computer spyware runs secretly in the background of the users' computers and covertly gathers users information and spreads it without the users knowledge.  

In practice however, there is nothing wrong with computer spyware operating in the background as long as the user knows that it is happening. Unfortunately, most users are unaware of the fact that they have software on their computers that tracks and reports on their Internet usage. Once installed the computer spyware monitors the activities of the user on the Internet and transmits that information in the background to the third parties like advertising companies.

All in all the data collected by computer spyware is often sent back to the marketing company, resulting in display of specific advertisements, pop-up ads and installing toolbars showed when users visit specific web sites. In this sense, computer spyware programs emerged as technologies used to obtain valuable customer information.  

Computer spyware may occupies resources of the computer that affects or alters the functions of existing application, in that sense it poses several risks. Commonly, the presence of spyware drains your computer's properties, slow your Internet connection, spy on your surfing, and even forcibly redirect your Web browser. Its programs range from annoying to the dangerous, including keyboard loggers and screen capture applications that can steal passwords and other sensitive information.

The programs are sometimes bundled in with shareware or freeware programs that can be downloaded from the Internet. Another setback of computer spyware is compromising the user's privacy by transmitting information about the user's behaviors. Furthermore, computer spyware detracts the usability and stability of the computing environment of the user. It also has the ability to introduce new security vulnerabilities to the infected host by downloading software updates. When the occurrence of computer spyware is widespread possible vulnerabilities put numerous amounts of computer risks.


Although the research community has spent limited time and effort on understanding the nature and extent of the spy ware program, computer experts and network practitioners agree that computer spyware is a real problem with increasingly negative effects. One particular proof of this conclusion comes from the Emerging Internet Research states that one among three companies has detected spyware on their system. Likewise, Earthlink research found out the occurrence of computer spyware in more than 2 million computers connected in their network with a total of 12.1 million various types of computer spy. Subsequent development of computer spyware technologies in combination will affect system and network capacity.

As an outmost consequence, a disastrous situation may occur if a network is seriously overloaded with different types of spyware distributed by computerized systems that are controlled by malicious people, in effect computer spyware may render further installations of viruses resulting to network breakdown.

As noted, since computer spyware gathers user information through the user's Internet connection usually for advertising purposes and considering the practices of some companies in order to ensure that their spyware cannot be easily removed, the best option to avoid computer spyware is prevention. You have to ensure that your system cannot and will not install programs automatically over the Internet or launch them automatically from email.

Moreover make sure that your operating system is fully patched against any known security vulnerabilities. And of course the best protection is enough knowledge of the risks of spyware and it works.

Stories can be submitted to HorrorStory@NewEnglandPCServices.com. 

Deadline for submission is June 30 and winners will be selected by July 31.

 

"We'd like to capture these stories, commiserate with our personal computer addicted friends and offer the top three story tellers a free service to keep them out of computer limbo," concluded Robbins.

Can the Media Spread Computer Viruses?

By: Devon Mcdaniel

If you believe what you hear in the media, there are an awful lot of viruses going around. No, I'm not talking about the make-you-sick kind of virus, though they get plenty of airtime, too. I'm talking about the kind of virus that enters via your internet connection rather than your nasal passages.

What the mainstream media often don't tell you--at least, in most radio and television newscasts and in the crucial headlines and opening paragraphs of newspaper articles-- is that many of these "viruses" are not viruses at all.

What Computer Viruses Really Are

The main reason the mainstream media always are in alarm over viruses is that they tend to call any malicious computer program a virus. In reality, there are at least eleven distinct types of malicious software, or malware, commonly affecting computers today. The most common of these are worms, Trojans, and spyware.

So, what's the difference between computer viruses and the other types of malware? The difference is that computer viruses are just about the only ones that regularly shut down computers and cause other obvious damage. The most common of the other kinds of malware--worms, Trojans, and spyware--are usually only detectable with a special scan.

The Real Danger of Computer Viruses

If the other types of malware are so unobtrusive that they can only be detected with a special scan, then what's to worry about? For starters, these programs are called malicious for a reason: they are designed to cause some kind of damage, if not to your computer, then to someone else's.

Worms are most famously used to damage, destroy, or disrupt other computer networks than the one on which the host computer is located. For instance, worms have been used by website owners to shut down rival websites by sending overwhelming numbers of requests to the computer that hosts that website. Worms have also been used to send out viruses to other computers, often without infecting the host machine--after all, what would it benefit the worm to shut down its host computer?

Trojans, in turn, are often used to insert worms and other malware on your computer, even if the Trojan itself does no damage.

But even if you don't care what happens to anyone else, you should still be concerned about one kind of malware: spyware, a kind of malware that, true to its name, collects data from your computer and sends it back to a remote host.

Most spyware is only interested in monitoring your internet usage so it can tell other programs, called adware, what advertising to popup on your computer. However, there are criminal spyware programs that steal financial data, or perform a thorough identity theft. Don't think you have personal or financial data on your computer? Some spyware programs contain a keylogger, which is a program that copies whatever you type, usually in order to snatch passwords. Even if you keep no financial information on your computer, if you ever buy anything over the web, the keylogger would allow its owner to buy stuff using the same information you typed in to buy stuff yourself.

Why Blame the Media?

Given the danger of all these different types of malware, isn't it a good thing that the mass media are becoming hysterical about it? And can't they be forgiven the sloppy reporting of calling Trojans, worms, spyware, and other malware "viruses"?

No, no, no.

This is a classic case of bad reporting doing more damage than no reporting at all. In this case, the damage bad reporting has done is to promote a common myth that goes something like this: "The only malicious software is a virus. Viruses damage your computer. Therefore, if my computer is working OK, my computer has no malicious software. I only need to scan my computer for problems when there is a sign of problems."

Thanks to this myth, many people complacently let their antivirus software go months out of date, not wanting to be bothered with scheduling an automatic update. Just as bad, many people don't have any extra software to combat the other types of malware that may not be covered by antivirus software.

In fact, it's not uncommon for people who have found malware on their computers after a scan to say, "but I never had malware on my computer before!" But how would they have known if they had never scanned!

Until the biggest mainstream media--and especially television--start educating the public about the need to have their computers automatically scanned at least daily, the world will continue to have major, drawn-out problems with malware that could have been wiped out as soon as soon as the anti-malware software makers discovered it.

And until that day, the mainstream media will have many more opportunities to run hysterical stories about "viruses," thereby forcing them to sell more newspapers and broadcast to even larger audiences of people who suck at the information trough yet somehow never become full.

Recycling & Disposing of Computers The Right Way

By: Les Finley

Computer recycling nowadays is easy to do and very commonplace as computers can be easily refurbished in order to provide 3rd world countries with older yet functioning models of computers. Disposing of computers properly is extremely important because if you sell your computer or give it away then the person who receives it has unlimited access to all of your personal information that was stored on it. If you leave your computer in the street for anyone to take away, then they would be able to access this private information as well.

In a day and age where it is easy to steal someone's identity with such a small amount of information, and companies are reaping the benefits of "ID Theft Prevention" plans, it is sad to think that a smart adult would forget how much personal information they've got stored on their computer. Every time you enter and save a small piece of personal information into a computer, it remains in the hard drive and usually takes a computer expert to wipe your computer clean of all of the tiny bits of your personal information. Any time you save a password or send an e-mail, that information remains no matter how many times you clean the "cookies" and free up some memory.

Any time you order something over the internet using a credit card number, that number gets sent to the company and is usually stored in their memory so that the next time you visit their website, shopping and paying is quicker and easier. As many as 9 million Americans have their identity stolen every year, but sadly, most of these victims are cautious consumers who happen to be targeted because of one little mistake. Disposing of your computer the wrong way could be the one little mistake that your creepy neighbor is waiting on in order for them to gain access to an abundance of your personal information.

With your personal information at the tip of their fingers, identity thieves can easily commit fraud by opening up new credit cards under your name and billing address, using your social security number to obtain illegal employment, get a loan or mortgage under your name, or even just an ID card with your name and their picture. There are no limits to what an identity thief can do with your personal information, and their reach stretches further if they have access to your e-mail accounts and internet pay systems.

The best way to protect yourself against identity theft is obviously to be a conscious consumer when it comes to using your credit cards, watch your credit history and make sure that details such as billing statements coincide with your personal records. It's important to watch what and where you spend your money, and to make sure it's only you doing the spending with your accounts.

It's okay to save personal information on your computer, as long as your computer remains in your hands. Once you are done with a computer either because it's old or broken or you're ready for an upgrade, there is only one safe way to dispose or recycle your old computer. In order to insure safety of your personal data and comply with environmental standards for computer disposal, your computer must be sent to a computer disposal or recycling company. Businesses such as those will properly dismantle a non-useable computer or will remove all of your personal information so that the computer is ready to be refurbished. Either way, years worth of your personal information that you entered into your computer will be properly wiped away and the theft of your identity via your trashed computer will no longer be a concern.

Enabling Your Computers for Wireless Access

By: Devon Mcdaniel

Built in wireless capabilities are becoming almost standard equipment on most laptop and home computers these days for a couple of reasons. One of the primary reasons is cost. Adding wireless capacity is so inexpensive that it would be silly for the manufacturers not to add it. The perceived value of any machine with wireless capacity far exceeds the cost to add it. Wireless is the wave of the future, so if the manufacturers want to stay ahead of the technology curve they need to add it to all but there most basic models.

However, if you're like most people you probably can't even check how much memory your computer has, let-alone if your computer is wireless enabled. Throw in the fact that you may not even know what wireless networking is and it's easy to ignore even trying to determine if your computer has that capacity. As a result, having ever taken the time to set it up is clearly out of the question.

However, since you bought your computer you've probably heard more and more about "going wireless" because it's becoming the hip thing to do. If that's the case with you or I've simply peaked your imagination then read a bit more because I've outlined a few things you can to do to check if your computer has wireless capabilities.

Laptops - Intel Centrino Mobile Technology
Computer manufacturers do less than a perfect job at explaining what this means but if you if your laptop came with this built in then that's good news for you! In a nutshell, it means that your laptop has wireless networking built right in and you don't have to do a thing. Intel Centrino Mobile Technology is a marketing name for a combination of the Intel Pentium M processor and Intel's' Pro Wireless card.

If you have Intel Centrino Mobile Technology then your computer should have a "Centrino" sticker on it somewhere. If you can't find a sticker but you suspect you had one at one time then simply do the following. Right click on your "My Computer" icon. It's probably on your desktop but if not then go to your Start Menu, find My Computer, right-click and select Properties. When the menu opens look at what it says after or under the word Computer.

On a side note, Intel Centrino Mobile Technology also increases battery life and allows manufacturers to build computers smaller. If you can't find anything referring to Intel Centrino Mobile Technology under the word Computer -- don't worry because as long as your laptop has a free card slot, installing wireless is a piece of cake.

Desktop Computers
If you're not sure whether or not your desktop computer has a wireless connection, the easiest thing to do is to simply turn it around and look for a small aerial sticking out of the back towards the bottom. If it's there then you are wireless enabled. On the other hand, if there's nothing then it's still possible that you have a wireless device in the computer, especially if you purchased anytime in 2005 or beyond. However, because it's not the best idea (unless you've done it before) to try and open up your computer to check something I'll show you a way to check, if your wireless enabled, using Windows.

Using Windows to Check Wireless Capacity
Rather than messing with your computers hardware to verify what you've got installed, you can just as easily check using your Windows' Device Manager. To use it, right click My Computer / Choose Manage / and then click Device Manager.

After you click Device Manager a list of everything you can install will appear on the right half of the screen. Take a look under Network adapters and ignore anything that says 10/100 or Ethernet because they are simply normal network connections -- not wireless ones. If there's anything else there, it could be a wireless device.

If you think you have a wireless device, but it has a yellow warning sign alongside its name in the Device Manager, you should take a look at it to see what's wrong by double clicking on it. Windows should then tell you why the device is not working at the moment and may even suggest that you go through its troubleshooter program. Do that before you do anything else.

If it turns out to be a driver problem, you should insert the driver CD that came with your computer. If you can't find the driver CD that came with your computer - don't worry because you should be able to find and then download the appropriate driver online. The first step would be to go to website of your computers manufacturer and do a search for the name of the wireless device that showed up in your Device Manager. Once you find the correct driver simply download it and follow the instructions.

After all this (actually about 5 minutes) you may discover that you don't have a wireless enabled computer -- oh well, those are the breaks. However, it's clearly better to find out your computers wireless capacity now -- before you go out and buy some wireless equipment and then realize that you didn't even need it.

Loction Aware Mobile Computing - Past , Present and Future

By: Kumaresh N

The question that always arises when a business is thinking of buying a mobile computer is "Will it be worth it?"

In many fields of work, the ability to keep on the move is vital in order to utilise time efficiently. Efficient utilisation of resources (ie: staff) can mean substantial savings in transportation costs and other non quantifyable costs such as increased customer attention, impact of on site maintenance and improved intercommunication within the business.

The importance of Mobile Computers has been highlighted in many fields of which a few are described below:

• For Estate Agents

Estate agents can work either at home or out in the field. With mobile computers they can be more productive. They can obtain current real estate information by accessing multiple listing services, which they can do from home, office or car when out with clients. They can provide clients with immediate feedback regarding specific homes or neighborhoods, and with faster loan approvals, since applications can be submitted on the spot. Therefore, mobile computers allow them to devote more time to clients.

• Emergency Services

Ability to recieve information on the move is vital where the emergency services are involved. Information regarding the address, type and other details of an incident can be dispatched quickly, via a CDPD system using mobile computers, to one or several appropriate mobile units which are in the vicinity of the incident.

Here the reliability and security implemented in the CDPD system would be of great advantage.

Police Incident Information Screen

• In courts

Defense counsels can take mobile computers in court. When the opposing counsel references a case which they are not familiar, they can use the computer to get direct, real-time access to on-line legal database services, where they can gather information on the case and related precedents. Therefore mobile computers allow immediate access to a wealth of information, making people better informed and prepared.

• In companies

Managers can use mobile computers in, say, critical presentations to major customers. They can access the latest market share information. At a small recess, they can revise the presentation to take advantage of this information. They can communicate with the office about possible new offers and call meetings for discussing responds to the new proposals. Therefore, mobile computers can leverage competitive advantages.

• Stock Information Collation/Control

In environments where access to stock is very limited ie: factory warehouses. The use of small portable electronic databases accessed via a mobile computer would be ideal.

Data collated could be directly written to a central database, via a CDPD network, which holds all stock information hence the need for transfer of data to the central computer at a later date is not necessary. This ensures that from the time that a stock count is completed, there is no inconsistency between the data input on the portable computers and the central database.

• Credit Card Verification

At Point of Sale (POS) terminals in shops and supermarkets, when customers use credit cards for transactions, the intercommunication required between the bank central computer and the POS terminal, in order to effect verification of the card usage, can take place quickly and securely over cellular channels using a mobile computer unit. This can speed up the transaction process and relieve congestion at the POS terminals.

• Taxi/Truck Dispatch

Using the idea of a centrally controlled dispatcher with several mobile units (taxis), mobile computing allows the taxis to be given full details of the dispatched job as well as allowing the taxis to communicate information about their whereabouts back to the central dispatch office. This system is also extremely useful in secure deliveries ie: Securicor. This allows a central computer to be able to track and recieve status information from all of its mobile secure delivery vans. Again, the security and reliabilty properties of the CDPD system shine through.

Taxi Dispatch Network

 

• Electronic Mail/Paging

Usage of a mobile unit to send and read emails is a very useful asset for any business individual, as it allows him/her to keep in touch with any colleagues as well as any urgent developments that may affect their work. Access to the Internet, using mobile computing technology, allows the individual to have vast arrays of knowledge at his/her fingertips.

Paging is also achievable here, giving even more intercommunication capability between individuals, using a single mobile computer device.

 

THE FUTURE

With the rapid technological advancements in Artificial Intelligence, Integrated Circuitry and increases in Computer Processor speeds, the future of mobile computing looks increasingly exciting.

With the emphasis increasingly on compact, small mobile computers, it may also be possible to have all the practicality of a mobile computer in the size of a hand held organizer or even smaller.

Use of Artificial Intelligence may allow mobile units to be the ultimate in personal secretaries, which can receive emails and paging messages, understand what they are about, and change the individuals personal schedule according to the message. This can then be checked by the individual to plan his/her day.

The working lifestyle will change, with the majority of people working from home, rather than commuting. This may be beneficial to the environment as less transportation will be utilised. This mobility aspect may be carried further in that, even in social spheres, people will interact via mobile stations, eliminating the need to venture outside of the house.

This scary concept of a world full of inanimate zombies sitting, locked to their mobile stations, accessing every sphere of their lives via the computer screen becomes ever more real as technology, especially in the field of mobile data communications, rapidly improves and, as shown below, trends are very much towards ubiquitous or mobile computing.

Major Trends in Computing

Indeed, technologies such as Interactive television and Video Image Compression already imply a certain degree of mobility in the home, ie. Home shopping etc. Using the mobile data communication technologies discussed, this mobility may be pushed to extreme.

The future of Mobile Computing is very promising indeed, although technology may go too far, causing detriment to society.

Computer Virus Facts and Removal Recommendations

By: M Wallace

Computer viruses will, unfortunately, always be with us. Whether by accident or design some malicious software will get onto computers. When it comes to computer problems it is important to differentiate between a computer virus and other issues. Firstly, some types of malware are referred to as computer virus. These include:



Generic "Computer Virus": A software program that can multiply by copying itself. Interestingly, a computer virus doesnt always cause significant problems contrary to popular belief. A computer virus can be spread to other users, which is also part of the reason why they are feared.



Trojan: As the name suggests pretends to be something other than what it is. These are dangerous software that at first appear to be innocent. However, once installed they wreak havoc on computer systems. Trojans do not spread from computer to computer.



Worm: Just about everyone has received a computer virus via email, although this is more often than not, a worm. Computer worms are generally spread via email and instant messages. Social networking is becoming a popular way for worms to spread from pc to pc.



Denial of Service: People who use the Internet may have heard the term, Denial of Service attack. Here the computer is actually taken over virtually by someone else. Once this happens, the attacker prevents the computer user from doing anything on the system.



While some viruses do not cause any problems, many are quite serious. They can delete files; some will even cause messages to appear on a computer screen. Others will cause a computer to constantly turn on and off.



Virus Removal Recommendations



While preventing virus infection is the priority, knowing something about virus removal is also important. The safest virus removal method is the use of good antivirus software. If such software is installed on a computer, the user has only to follow the instructions provided.



If there is no antivirus software, then the main solution will be either to take the machine to a computer technician or search online for a fix. There are many support groups online that are dedicated to finding virus removal solutions. Many of these forums are free and easy to access.



A new computer virus is released every day, so the best way to prevent computer problems is to be protected. To do certain steps should be followed:



If you receive an attachment via email from an unknown source do not open it. It is always best to err on the side of caution. This applies to files sent via instant messaging as well.



Check for viruses on any thumb drive or jump drive before using it. In fact, it is advisable to disable the autorun feature on your computer.



Be careful of where you download files online. While there are many sites that offer free games and movies, etc, not all are safe so it is best to be cautious.



Install and Update Antivirus Programs



While virus removal will deal with the immediate problem, the headaches associated with them should be minimized as much as possible. Exercising due care in and keeping abreast of new viruses is always the safest way to prevent a computer virus.

Computer Repair Tools That Are Easy To Use and Affordable

By: Bayne Schulstad

There are software and internet computer repair tools that can be used to diagnose, repair and cleanup your computer. These should be considered essential pieces of your computer repair tool kit, before you call an onsite computer repair service. There are situations where you won't be able to fix computer problems on your own, but with the proper computer repair tools, you may be able to get your computer running efficiently in a matter of minutes.

 

Current Anti-Virus Software:

 

One of the most important things to have in your computer repair tool kit is current anti-virus software with updated definitions. There are affordable anti-virus software products you can purchase on the Internet with annual renewals and there are some free online anti-virus scans. Since new viruses come out every day, it is important your definitions are updated frequently or automatically and that you perform regularly scheduled system scans. Change your settings on anti-virus software to perform these important functions.

 

Registry Cleaners:

 

Many viruses target the computer registry files to make unauthorized changes that prevent your computer from running properly. When it comes to registry cleaners, you can buy packaged registry cleaners or you can find some online choices to keep your computer running correctly for a nominal fee.

 

Disk Cleanup:

 

Disk Cleanup is in your control panel, under "administrative tools" and computer management functions. As one of the regular computer repair tools that can be scheduled to run automatically, you should perform disk cleanup on a weekly basis, at least, if you use your computer for Internet browsing because this can eliminate temporary Internet files that take a lot of room. Another way you can keep memory free and eliminate "tracking cookies" is to go under "tools" on your Internet browser, then "Internet options" and under the general tab, "delete" browsing history. Check the box to have browsing history and temporary files deleted automatically.

 

Defragmenting Your Hard Drive:

 

One of the helpful tools to schedule in control panel, under "administrative tools" is the "defragmentation" or "defrag" of your hard drive. This groups files together and frees up hard disk space to allow better storage and isolates corrupted data files. Defragging the hard drive on a regular basis can be one of the helpful computer repair tools that are contained within your computer's control panel and can make your computer operate more efficiently.

 

Data Backup and Recovery:

 

When your computer crashes, the most crucial computer repair tools may be the data backup and recovery of your hard drive files. If you have an exact mirror backup of the hard-drive, including the programs, driver software and all of your configuration settings, it is much easier to rebuild the computer, in the event of hard disk failure. An onsite computer repair service can assist with this crucial part of your computer repair tool kit. They might suggest online data backup services, or install an external or internal mirror hard drive. Sometimes, you can rebuild your system back to a restore point, from the operating system software.

 

There are some helpful computer repair tools that can be easy to use and can maintain your computer automatically, through the proper settings. You might consider onsite computer repair service for some suggestions regarding the best computer repair tools to improve computer performance.

Everything You Need to Know about Computer Hardware

By: Frankie Zimmerman

Physical parts of computer come under the category of computer hardware. It can be changed once in a while in comparison with computer software. Normal users don't see most computer hardware because it is enclosed as embedded systems. The term computer hardware is generally used for personal computers.

Internal computer hardware consists of motherboard having central processing unit and random access memory. Random access memory provides temporary storage of data where as CPU is used for doing all type of calculations. Second major component of computer hardware is Bus that is used to make common connection between several circuits. People can choose any type of buses as per their needs. Generally these are PCI bus, PCI-E or AGP bus, ISA bus that is outdated and UCB that is commonly used.

Computer can't be run without power supply that is case including transformer, voltage control and fan. Computer hardware includes storage controllers that are helpful in controlling the hard disk, floppy disk, CD-ROM and other drives. These can be assembled on the motherboard or expansion card directly.

Video display controller is used to generate output for the computer display. Computer bus controllers are also come under computer hardware. These are used to connect computer to external peripheral devices like printers and scanners.

Sometimes computer hardware includes some removable media writers such as CD, CD-ROM Drive, CD Writer, DVD, DVD-ROM Drive, DVD writer, DVD-RAM Drive, Floppy disk and Zip drive. These are not permanently fixed in the computers and whenever you want you can remove them easily.

Tape drive, Internal storage and hard disk of the computer offers different levels of data storage like tape drive offers backup or long-term storage, Internal storage keeps the data safe inside the computer for later use while the hard disk offers medium-term storage of data. Sound card usually translates signals from the system board into analog voltage levels. It has terminals to plug in speakers.

If you want to connect your computer to other computer or Internet you require computer networking that helps you to communicate with other computers. Other networking hardware includes modem that is used for dial-up connection, and network card that is used for DSL/Cable Internet or connect to other computers.

Computer hardware includes internal as well as external components of a computer system. External components of computer hardware consist of some essential input/output devices such as keyboard, mouse and monitor. Other useful computer hardware components are speakers, headset, joystick, trackball, image scanner, microphone, etc.

Computer Repair Made Simple (...or, uh simpl-er)

By: Mitchell Sears

Owing a computer is almost essential in today's world. With the introduction of the internet and the convenience of email as a method of communication, it's easy to see why most people want to have a computer in their home or office.

Computers are like anything else and there are times when they don't operate as planned. It's frustrating to be sitting at your desk ready to play a game or work on a document only to find that your computer isn't being cooperative.

When it comes to computer repair it's often wise to seek out professional help. A computer technician is specially trained to evaluate the problem and offer the best possible solution.

There are certain types of computer repair that you might want to undertake yourself. These are usually minor fixes that can be handled with a bit of instruction and attention to detail.

A computer repair that you might be able to take care of yourself is the replacement of the computer's battery or fan. Every desktop computer has a fan inside of it. This fan is used to keep the computer's components cool. It's essential that the fan operates efficiently to ensure that the computer doesn't become overheated.

The first sign that your computer's fan might not be operating properly is that you'll notice a different sound when you start or run your computer. Instead of immediately taking it to a computer repair shop, take a moment to test the fan.

Computers typically have two fans. One is used to cool the power supply and the other is used to cool the CPU. Open the cover of the computer and listen. If the sound does appear to be coming from the fan that cools the CPU you'll want to replace it.

If the computer is still under warranty than this type of computer repair will be done free of charge. Follow the instructions you were given for repairs at the time of purchase. If the warranty period has elapsed you can either take it to a computer repair shop or do it yourself.

The very first and most important step when doing any computer repair is to unplug the computer from the electrical outlet. You'll then need to examine the fan to see how it's connected. It will probably be attached by a few small screws. Once these are loosened you'll need to disconnect the fan from its power supply. This will be one or two small clips. Then take the fan to your computer repair shop and purchase a new one.

After replacing it, reattach the cover and plug the machine in. The fan should operate perfectly now and the noise that you were hearing will have disappeared.

Sometimes a computer will make noises because a piece of hardware isn't attached properly. One of the likely culprits is the CD-Rom or DVD drive. Again for this type of computer repair, you'll want to carefully remove the cover and listen for the source of the noise. After tightening the screws that hold the hardware in place and reattaching the cover, plug the machine in and listen if the offending noise is gone.

When it comes to computer repair it's important to be safe and thorough. Computers are an expensive investment and keeping them running efficiently is crucial. If you are comfortable handling a small computer repair yourself, give it a try. If you're not comfortable, take the machine to a local computer repair shop and allow the experts to do their job.

You Can Learn About Computers

By: Mitchell Sears

Computers are a part of today's bustling world and play a role in everybody's life, young or old, whether they like it or not. A version of a computer, whether it be highly technologically advanced or not can be found in household appliances such as refrigerators, ovens, toasters and microwave ovens. Cars have their own unique kind of computers, as do televisions, DVD players and so much more. But when we think computer what comes to mind first is generally what is known as a PC (or personal computer). Almost every household has at least one and most companies could not be without one today. So much is done on the computer and over the computer.

A personal computer can mean so many things to so many people and it has a variety of functions. For students it's great for doing research using the Internet as well as typing up essays and papers for school. The Internet is a tremendous resource for anyone wanting to learn about practically any subject from animals to authors and everything in between. And what of e-mail? Twenty, thirty years ago no one could have conceived of the idea that a person could sit down in front of a computer screen and type a message to someone who is close or far away and then send it to them and have it received almost instantly! It's quite an amazing development for our world. And for those who enjoy solitary recreational pursuits, there are a variety of games that can be played on computers. One can also watch movies and listen to music via the use of a computer.

A computer is often thought of as a machine that processes information in a timely manner and is very general-purpose in its application. An individual types information into the computer through the use of the keyboard as well as the mouse and watches what he/she is typing materialize on the computer screen. The computer then begins the process of sorting through the data it is receiving and processing it as is necessary. The computer user can then save what he sees in front of him on the hard drive of the computer or onto a floppy disk or CD. If saved to the hard drive then the information cannot be used on any other computer but if saved on a disk that information has now become portable and can be used on other computers and not just that one in particular.

Every computer contains certain elements which in brief include the CPU or central processing unit or the brain of the desktop computer, the memory where information is stored, the motherboard or main circuit board, the power supply which regulates electricity going through the computer, the hard drive, or permanent storage, the operating system, or basic software, the integrated drive electronics controller or IDE, the peripheral component interconnect bus or PCI which allows other items to plug into it, the small computer system or SCSI which allows devices such as scanners to be plugged into it, the accelerated graphics port or AGP which is used by the graphics card which in turn translates visual information from the computer into a format it can read. And last but certainly not least is the sound card, which allows the computer to record as well as play anything with an audio element to it such as a CD that is accompanied by music.

Single Board Computers: Pros and Cons

By: Mitchell Sears

When most people think of computers, the image of a PC or laptop comes to mind. Some may even recall the football field size computers of the 1960's and 70's before the emergence of the PC. Very few people would picture single board computers , even if there was one sitting right in front of them! A single board computer is the terminology used for a printed circuit board that contains a processor, memory, I/O (input/output) and a clock. Single board computers (aka SBC's) resemble the motherboard contained in a typical PC, but include all the elements of a basic computer within it's small design. Since the early 1980's, the technology behind this type of computers has been used in industrial manufacturing and computerized product design to apply basic processing functions for high-tech product features.

Usage of Single Board Computers

Also commonly referred to as embedded computers, single board computers are used in products from airplanes and rocket ships, to toys and high performance athletic shoes. Almost everyone uses single board computers without being aware of their existence. Most products that utilize computer technology (such as fax machines, cameras, cell phones, etc) contain embedded single board computers. While these tiny computers can host a full size operating system such as Windows XP, most SBC's have internal operating systems that take up much less space. Simpler operating systems equal a lower cost per computer. Software for single board computers is generally contained on a flash memory system or ROM chip. Quality indictors for single board systems include processor performance, I/O compatibility, SSD storage and wireless capabilities.

Pros and Cons of Single Board Computers

There are both advantages and disadvantages to using SBC's for industrial and product enhancement. Deciding whether or not to implement single board computer technology is largely a matter of application necessity and cost. Some of the deciding factors on using them include:

+ Pro : Current technologies have increased the capability of the single board computer, while reducing its size and cost.

+ Pro : Wireless technology has made it possible for easy internet access via SBC.

+ Pro : The competitive market has greatly expanding the options and functionalities available for SBC's.

+ Pro : Advanced computer technology offers reliability for industrial manufacturers and quality products for vendors using SBC's.

- Con : Incorporation can be costly for high volume products and applications.

- Con : Some applications require customized sizes or I/O functions that are not compatible with standard SBC's.

Single Board Computer Technologies

While all SBC's are built using similar standards, different technologies can be included with individual SBC's. Video capability, Ethernet access functionality and digital computer technologies are just some of the features that can be incorporated into a single board computer. In general, SBC's can be as simple or as complex as an application demands. Additionally, supplemental hardware such as backplanes and mezzanine structures can significantly increase the functionality of a single board computer.

Whether you also are getting a computer for personal or business employ, selecting the straight components can be a difficult task. Therefore the way do you really ensure that you buy exactly what you really want?

Computer memory is really important to computer operation. Memory is answerable for a variety of jobs in the pc method.  Personal computer Memory is the heart of your personal computer.  The memory is regularly known as RAM, (Random Access Memory).  It's very an internal storage area in the personal computer.     Understanding computer memory is really important; the memory is what enables your PC to operate.  RAM is the most typical and the majority often used personal computer memory.  There are also numerous techniques through which the computer memory might be classified: But the easiest methodology to classify the computer memory is to know the differences of the primary (or deciding) and secondary (or auxiliary) storage devices.  The memory includes physical computer memory and a memory controller that physically accesses the pc memory.

The first sort of computer memory is static pc memory. This is the amount of space you actually have to store stuff on your personal computer. When you really save photos, video, music, documents and anything else on your personal computer, of those files have up portions of your static computer memory.

Memory cards had two basic forms of memory: Single is known because (RAM) this stands for random access memory. The other is (ROM) other wise renowned because read only memory. Once you really experience downloaded your info onto the card you actually will be ready to store it for because long because you need. However, you has to then plug the card back into your personal computer to view, print it or download the info back onto your computer. Your data is going to remain on the card until you choose to remove it.  You can keep adding info to the card until you've used all of the memory space. You actually may also erase the card and reuse it at any time.

Motherboards having four memory slots: A some of the motherboards suffer 4 RAM slots. Hence, we could feel that we can attach four GB of RAM to the personal computer which may greatly increase the performance of the personal computer. Yes, we is ready to connect four GB physically nevertheless some of the 32-piece operating secrets can also not give the entire four GB RAM of memory to us inlieu it sets a side a few an element of the memory for internal uses and provides around three GB for us. So, if we need to utilize all the memory slots for increasing the performance the better option is to attach 2 1 GB memory modules to 2 slots and a pair of 512 MB memory modules to the remaining slots. Even if we add 4 1 GB memory modules to each of the slots we also are going to get the performance that is just about same as 3 GB best. Hence, we also are unnecessarily spending money on one 1 GB memory module.

Well that's getting ready it, I hope I have helped you. Just don't forget to keep your pc clean plus maintain correctly, and it will live a long life.

In the process of the computer recycling the old and out dated computers or its parts are extracted and are reused. Recycling procedure is also used in replacing the old parts of a computer with the new ones. Many times a situation arises when important files that are being stored in the hard disk of the computer become corrupt and you can not access them. For solving these kinds of problems the computers are being recycled. With the advent of the modern techniques of computer recycling it has become possible to recover unrecoverable data. So this method is the best if you want to retrieve your data or any operating parts and reuse them.

Different materials are used in the manufacturing of computers. These materials can be retrieved and removed in the computer recycling process. Some of these materials are used in abundance they are: iron, silicon, aluminum, plastic, tin etc. If a new computer is constructed by using these extracted materials then the cost of the new computer is cut down to a great extent. Computers also have some materials like gold and copper which are quiet valuable if extracted safely.

If not recycled carefully, obsolete and out dated computer can produce toxins and cancer generating substances. With the constant growth of technologies the computer recycling methods are recognized around the world.

There are number of computer recycling methods that are employed with the increasing demands. Some of these methods through which the recycling process is carried out are:

1 : Donating the computers is one of the basic computer recycling procedures. Under this procedure the consumers donate their computers directly to any school, institution, organizations, charities, or a recycling unit for a refurbish, or by simply sending the computers to the company or dealer itself.
2 : Many companies or manufacturer gives an exchange or a replace of an old computer with the purchase of a new one. They repair these computers if required and resell them accordingly. Many online marketing website also deals in used computers.
3 : Professional IT companies seek a commercial method for computer recycling process. They deal with the manufactures or the companies directly. The reason behind this is that the computers to be recycled by an organization are in a bulk and thus the recycling procedure becomes very complicated.  

There are also some rule and regulations related with the recycling of the computers. These rules and regulation are made to keep the environment clean and pollution free. It is mandatory to follow these laws and guidelines so as to maintain the ecological balance. Generally these laws and regulations are framed by the local authorities keeping the human hazards in mind. It is also important that the data and the information stored in the computers are destroyed completely. Many times these data and information are misplaced or stolen and this results in identity crisis issues. This might result in a financial set back and loss of market value in the market. So it is very essential that one should follow computer disposal procedure in a secure manner.

Dangers On Your Desktop: Computer Virus as well as Spyware

By: Josue Maynard

So have you bought a new computer at home for yourself and for your kids? Your computer is sure going to be useful to you and your family. You can now use your computer to store important data, work on reports and much much more. Your children can now surf the internet, play games and learn new tools and software programs. By purchasing a computer you open the world to the big bad world of the internet. Why is the internet a big bad world? The internet can prove to be a big bad world for you if you don't take care to protect your computer from internet threats. In fact the internet is the most comprehensive source of information available at the click of the button today. You can search for diverse topics. You can use the internet to access your bank accounts, to join newsgroups, to entertain yourselves, listen to music and even watch movies. You can even use the internet to speak to people at low costs through VOIP (Voice over Transmission Protocol) all over the world. There are very few boundaries associated with the internet.

But, you should be wary of all the threats that the internet can invite to your computer. First of all let's talk a little about computer viruses. A computer virus is a software program written by a person which can prove to be a threat to the security of your computer. It gains access to your computer through programs downloaded from the internet and even from seemingly harmless emails. It can delete all your important files after it loads itself on the system or it can just make your hard disk unusable. It can disable your important device drivers and can do hundreds of other damaging things to your computer. The software program (or computer virus) spreads rapidly through the internet and can invade thousands of computers a minute.

The best solution against virus invasion is the installation of good antivirus software. Norton Antivirus by Symantec proves to be one of the better paid antivirus solutions. It provides tight security in comparison to some of the other antivirus softwares and also updates itself regularly. The other important software you can use to protect your computer is installing a firewall. A firewall restricts unauthorized access to your computer by people on the internet who are constantly on the lookout for open ports on computers. In addition, if you use the internet to make purchases with your credit card, make sure you are using a trusted and secure site. Secured sites conduct financial transactions using secure software like Verisign so that your private information cannot be viewed by unauthorized people.

When using services or programs that use passwords, always use passwords that are difficult to guess by others. Do not ever open unauthorized emails as they might be harmful to your computer. Unauthorized or unsolicited mails are the most common path to spreads a virus through the internet.

When you visit some sites, a spyware program maybe installed on your computer automatically by those sites. A spyware program is a program that collects all information on your computer including private information that can then be made known to unauthorized people. Using an anti-spyware program like Spyware Blocker or Ad-Aware comes in handy. These programs work to prevent spyware from automatically installing on your computer in the first place. You must also delete your cookies regularly. A cookie is a small file that is automatically installed on your computer and it accesses the information on your computer including the web sites that you have visited and sends all information back to people who need access to that information.

If you use a little care, you can provide some protection to you and your computer. However, the only way to completely eliminate any threats is not to go online in the first place. I don't think that is a viable option in today's world. Good luck!
