Wholesale Computer Parts - Getting Good Deals

Wholesale Computer Parts - Getting Good Deals by Morgan Hamilton

Have you noticed that most branded computers today have become very expensive? If you have, then you probably have been shopping in the market for a new computer system. You might be confused why they're so expensive when prices have fallen in certain sectors that contribute to the making of computers. For example, the prices of memory have hit an all time low. This is because of the enhancements in manufacturing volumes of memory manufacturers.
The prices of mother boards and other assorted computer parts have also decreased significantly. Well, you have to remember that the branded computer manufacturers are in the business to make their own profits. That is why good computers remain expensive despite the reduction that we have been witnessing. Fortunately, you can still avail yourself of a good computer system these days. You can do this by sourcing your computer from dealers who specialize in wholesale computer parts. A lot of people are sourcing out and building their own computer through wholesale computer parts. However, some folks think that these parts are in some way inferior to the parts available in branded computers. To be honest, I used to be one of those people.
In the past, I believed that cheap and inefficient computer parts manufacturers use wholesale computer parts to offload their inferior stock on unsuspecting customers. However, my views about this issue changed when my computer broke down. I got a quote that was very high when I took it to the authorized dealer. I had no choice but to go to a local wholesale computer parts dealer because my funds are low and I desperately need to have my computer fixed. I was amazed when I saw that this wholesale computer parts dealer has his own repair service. The repair quote I got was a fraction of what the authorized dealer had given me after they opened up my computer and diagnosed the problem. Naturally, I was curious as to what had created the difference, so I suspiciously eyed the wholesale computer parts on display. The dealer sensed that I was suspicious so he opened up my computer to show me that the replacement parts were the same with what my existing computer had. He willingly explained the wholesale computer parts business to me when I asked him how this was possible.
He patiently explained that computer parts manufacturers usually manufacture more parts than required by an order from a branded computer manufacturer. This is an in-built quality control feature that ensures that a sudden spurt in demand or a quality crisis can be handled quickly and efficiently. When the order is processed without incident, the excess parts are then offloaded to dealers for a huge discount. These equally good computer parts are then sold for a discount to users like you and me.

Tip for Computer - omComputer Security, Viruses And Threats.

Computer Security, Viruses And Threats. by Drew Pilton

Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important for the information on the computer to be stored and kept properly. It is also extremely important for people on computers to protect their computer from data loss, misuse, and abuse. For example, it is crucial for businesses to keep information they have secure so that hackers can't access the information. Home users also need to take means to make sure that their credit card numbers are secure when they are participating in online transactions. A computer security risk is any action that could cause loss of information, software, data, processing incompatibilities, or cause damage to computer hardware, a lot of these are planned to do damage. An intentional breach in computer security is known as a computer crime which is slightly different from a cybercrime. A cybercrime is known as illegal acts based on the internet and is one of the FBI's top priorities. There are several distinct categories for people that cause cybercrimes, and they are refered to as hacker, cracker, cyberterrorist, cyberextortionist, unethical employee, script kiddie and corporate spy.*The Hacker.The term hacker was actually known as a good word but now it has a very negative view. A hacker is defined as someone who accesses a computer or computer network unlawfully. They often claim that they do this to find leaks in the security of a network.*The Cracker.The term cracker has never been associated with something positive this refers to someone how intentionally access a computer or computer network for evil reasons. It's basically an evil hacker. They access it with the intent of destroying, or stealing information. Both crackers and hackers are very advanced with network skills. *The Cyberterrorist.A cyberterrorist is someone who uses a computer network or the internet to destroy computers for political reasons. It's just like a regular terrorist attack because it requires highly skilled individuals, millions of dollars to implement, and years of planning.*The Cyberextortionist.The term cyberextortionist refers to someone who uses emails as an offensive force. They would usually send a company a very threatening email stating that they will release some confidential information, exploit a security leak, or launch an attack that will harm a company's network. They will request a paid sum of money to prevent the threat from being carried out, a bit like black mailing.*The Unethical Employee.An unethical employee is an employee that illegally accesses their company's network for numerous reasons. One could be the money they can get from selling top secret information, or some may be bitter and want revenge.*The Script Kiddie.A script kiddie is someone who is like a cracker because they may have the intentions of doing harm, but they usually lack the technical skills. They are usually silly teenagers that use prewritten hacking and cracking programs. *The Corporate Spy.A corporate spy has extremely high computer and network skills and is hired to break into a specific computer or computer network to steal or delete data and information. Shady companies hire these type people in a practice known as corporate espionage. They do this to gain an advantage over their competition an illegal practice.
Business and home users must do their best to protect or safeguard their computers from security risks. The next part of this article will give some pointers to help protect your computer. However, one must remember that there is no one hundred percent guarantee way to protect your computer so becoming more knowledgeable about them is a must during these days.
When you transfer information over a network it has a high security risk compared to information transmitted in a business network because the administrators usually take some extreme measures to help protect against security risks. Over the internet there is no powerful administrator which makes the risk a lot higher. If your not sure if your computer is vulnerable to a computer risk than you can always use some-type of online security service which is a website that checks your computer for email and Internet vulnerabilities. The company will then give some pointers on how to correct these vulnerabilities. The Computer Emergency Response Team Coordination Center is a place that can do this. The typical network attacks that puts computers at risk includes viruses, worms, spoofing, Trojan horses, and denial of service attacks. Every unprotected computer is vulnerable to a computer virus which is a potentially harming computer program that infects a computer negatively and altering the way the computer operates without the user's consent. Once the virus is in the computer it can spread throughout infecting other files and potentially damaging the operating system itself. It's similar to a bacteria virus that infects humans because it gets into the body through small openings and can spread to other parts of the body and can cause some damage. The similarity is, the best way to avoid is preparation. A computer worm is a program that repeatedly copies itself and is very similar to a computer virus. However the difference is that a virus needs to attach itself to an executable file and become a part of it. A computer worm doesn't need to do that, it copies itself to other networks and eats up a lot of bandwidth. A Trojan Horse named after the famous Greek myth and is used to describe a program that secretly hides and actually looks like a legitimate program but is a fake. A certain action usually triggers the Trojan horse, and unlike viruses and worms it will not replicate itself. Computer viruses, worms, and Trojan horses are all classified as malicious-logic programs which are just programs that deliberately harm a computer. Although these are the common three there are many more variations and it would be almost impossible to list them. You know when a computer is infected by a virus, worm, or Trojan horse if your computer displays one or more of these things:
* Screen shots of weird messages or pictures appear.* You have less available memory than you expected.* Music or sounds plays randomly.* Files get corrupted.* Programs are files don't work properly.* Unknown files or programs randomly appear.* System properties fluctuate.
Computer viruses, worms, and Trojan horses deliver their payload or instructions through three common ways.1 - When an individual runs an infected program so if you download a lot of things you should always scan the files before executing, especially executable files.
2 - When an individual boots a computer with an infected drive, so that is why it's important to not leave removable media in your computer when you shut it down.
3 - When an unprotected computer connects to a network. Today, a very common way that people get a computer virus, worm, or Trojan horse is when they open up an infected file through an email attachment.
There are literally thousands of malicious logic programs and new ones come out by the numbers so that's why it's important to keep up to date with new ones that come out each day. Many websites keep track of this. There is no known method for providing 100% protection for any computer or computer network from computer viruses, worms, and Trojan horses, but people can take several precautions to significantly reduce their chances of being infected by one of those malicious programs. Whenever you start a computer you should have no removable media in the drives. This goes for CD, DVD, and floppy disks. When the computer starts up it tries to execute a boot sector on the drives and even if it's unsuccessful any given virus on the boot sector can infect the computer's hard disk. If you must start the computer using removable media for any reason, such as when the hard disk fails and you are trying to reformat the drive make sure that the disk is not infected.
How can you protect your computer? The best way to protect your computer from any of the above is by using good quality internet securities software. Purchasing this from a reputable security company is recommended to ensure that your software is kept up to date with the most recent virus signatures. If you are not up to date an unrecognised virus will not be stopped by the software. A full security package will protect you from viruses, Worms, Trojan horses, keyloggers and will detect when a hacker is attempting to hack into your computer and prevent them from gaining access when you are online or connected to a network. It is not advisable to use a free antivirus service as these do not provide adequate protection and are a false economy. Recommended internet security software companies are:- Norton, McAfee and others.

Installing Computer Components without the Disk

Installing Computer Components without the Disk by Ferrel Kenda

Have you ever found a used computer component then attempted to install it on your computer only to find that you need the accompanying software CD? Did you get a great deal on a slightly used printer from the local Goodwill store and couldn't use it because your computer wouldn't recognize it? Nothing is more frustrating than attempting to accomplish a do-it-yourself upgrade and getting stumped by a missing disk. Do not dismay, although sometimes it will require some diligence, there are avenues that may be pursued to allocate the AWOL info. The only assumption that I will make is that your computer's operating system is Windows since it is a more common interface. Being a thrifty (some may say cheap) troubleshooter, I always try the cheapest and quickest possibilities first, then work my way up.
When installing any new diskless (if that's a word) component on your computer, the first thing you should try is the Add New Hardware option located in the Control Panel. Select the component in question and see if your system will recognize it. Windows has many proprietary and generic drivers stowed away for just this occasion, and will likely have the files required by most common brand name peripherals. Windows will then self-install the component and no further action will be required.
If such is not the case, don't throw up your hands yet, the search has just begun. Assuming that you have internet access, (oops, that's another assumption isn't it?) use a search engine to locate the home site of your component manufacturer. Most offer free downloadable drivers, upgrades, patches, and software for each of their particular models. Be sure to have the correct model number of the component in question as drivers can be very specific in nature, i. e. not all Hewlett-Packard Printers use the same driver, and they are not interchangeable. When you find the correct driver, save it to a floppy disk, jump drive, or whatever is handy. If you save it to the hard drive, take note of where it is being saved so you will be able to find it later. Go back to the Add New Hardware option in the Control Panel and when the installation program asks for the disk, just select the drive or file where the driver was saved. Windows does the rest.
If the manufacturer is for any reason not available, there are many sites in operation that specialize in drivers and various types of installation software. The process will then be identical to the above procedure once the appropriate driver is located.
If at this point, your quest has been unfruitful, you may need to resort to more drastic measures. Keep in mind that a vast majority of situations will be resolved by the first three scenarios. As I said, some diligence may be required. If you are still left with a lifeless component, check back with the Goodwill store, yard sales, friends, or flea markets. Many have bins full of unwanted installation disks donated or discarded by previous owners. You may just luck out. Lastly, it may become necessary to procure the disk directly from the manufacturer via snail mail or contact them using their toll-free number.
If you have exhausted all of these options, chances are that the component was not such a good deal after all, and you might be better off just trashing it and buying another more cooperative model. In any case, 99.9% of driver related issues can be overcome by one of the methods listed above. It may take more time and patience than you wish to spend, but can be a worthwhile pursuit. Happy hunting!

Data Recovery The Truth

Data Recovery The Truth by Daniel Millions

At some point in time, everyone who owns a computer will experience the trials and tribulations of hard drive failure. The reasons behind it vary, and could include everything from a human error to damages resulting from flood or water. Viruses can play a role as well, along with many other factors. For many years, the need to recover data that has been lost or destroyed has made data recovery such a very valuable asset.
Almost all hard drives can be recovered. Normally, if the drive is making a ticking or a scratching noise, you can use certain software programs to recover the data. Sometimes, due to age or bad parts, the aperture arm in the hard drive can fail, or the platters can become damaged and lose the data that they hold. If you cant recover the information with software, you will need to send the hard drive off and have it either rebuilt or have technicians recover your data.
Data recovery is always an option, from hard drives that are 2 GB in size to the largest of over 300 GB or more of data. No matter what size hard drive you have, the data can generally be recovered. Keep in mind that if you have had a computer crash, you will need to send the hard drive off to have the data recovered by technicians.
One of the key benefits of data recovery is the fact that information can also be retrieved from the recycle bin as well. Partition recovery, and even information that has been lost somewhere on the disk can be retrieved as well. Even though it may seem like your data is gone forever - the technicians that specialize in data recovery can retrieve it.
From Windows to Mac, everything can be recovered. There are different filing structures and formats, including NTFS and FAT32. These are common Windows filing structures, and hold all of the information for your hard.
Those of you who have multiple hard drives in your computer, can rest assured that RAID configurations can also be recovered. If a single hard drive on the RAID configuration fails, the RAID setup will absorb the blow and there wont be a loss of data. On the other hand, if the entire RAID configuration crashes, it will crash big time. Whenever this happens, you will need to send it off and have technicians restore both the RAID hardware and software.
Anytime your hard drive happens to crash or malfunction, data recovery is there to help you get back your files. Whether they are personally files or very important files that are need for business - you can put your trust in data recovery and know that you will get everything the back the way it was.

Do The Media Spread Computer Viruses?

Do The Media Spread Computer Viruses? by John Pawlett

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.

Computer Components for Idiots

Computer Components for Idiots by John Pawlett

There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, its not a computer.
The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. Thats your basic computer.
Mother WHAT?
The motherboard ("mobo" for short) is the foundation. Everything attaches to the mobo -- the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between the computer parts.
CPU
If the motherboard is the nervous system, then the CPU is the brain. Most of the mathematical manipulations that make computers operate are done by the CPU. Other components may also have their own processors, but their results still have to be passed through the CPU.
The speed of the computer is usually measured by the speed of the CPU. Even though other factors also affect overall speed, the CPU rating is generally seen as the single most important measure of performance.
Modern CPUs are usually rated between 2.0 GHz and 3.0 GHz, although each passing month will see increasing performance. This measurement refer to the number of calculations the processor can make in 1 second. The higher the number, the faster (better) the computer.
CPUs generate a lot of heat doing this work, so they need a heat sink and fan to keep them from overheating. Heat is a major enemy of the computer and directly affects its life span.
Computer Memory
RAM (Random Access Memory) is the part of the computer that stores information the computer needs while it is operating. It is Random Access because the computer can get the data in any order, not necessarily the order in which it is stored. Generally speaking, the more RAM the better. 512 to 1024 megabytes is common for memory.
The most common type of RAM these days is DDR-SDRAM, which stands for double-data-rate synchronous dynamic random access memory. We already know what the RAM part means. DDR means that the data is accessed twice as fast as ordinary RAM.
The latest type of RAM is DDR2. It offers even faster access rates and is quickly becoming the standard for computer memory.
Hard Drive
All the data contained in RAM is lost when the computer is turned off, so there has to be a place to store it permanently. This is what the hard disk is for.
It holds the computers operating system. An operating system like Windows uses around 4 gigabytes of hard drive space. The extra space is used to install computer programs and to store your personal data.
80 gigabyte hard drives are common, but 400 GB units are available. Furthermore, you can install more than 1 in a computer case for added security and convenience.
Peripherals
All you need to complete the basic computer system is a monitor, keyboard and mouse.
Accessories like a printer or scanner are useful for office work, and gamers will probably want to add speakers and joystick controls.
So there you have it. The basic computer needs just 7 major components. For the best performance, these components must integrate well. The motherboard is the most important component for determining the type and specification of the other parts. Choosing an appropriate mobo for your computer needs is the first step and may require a quick call to your local geek.
Soon YOU will be considered the local geek!

Computer Sale Article.

Computer Sale by preecha9999Computer Sale Article.A device or system that is capableof carrying out a sequence of operations in defined manner. The operations are frequently numeric computations or data manipulations, but also include data input and output.Under Threat From Poor Computer SecurityLocal businessman and computer expert Preecha, who runs Hybrid Computers, is warning home computer users in the Aylesbury area to beware that they are leaving themselves open to identity thelft, spying and viruses from unscrupulous broadvband hackers.Typical home surfers shop and bank online, they use popular auction sites such as eBay and are likely to book their holiday on the net too. Lack of computer security is a growing menace for people unaware of the risks that using an unsecured internet connection can cause. The increasing use of laptops that use wireless broadband is adding to the problem. Surfing the net while relaxing in the garden during the warm summer weather may seem a luxury, but vulnerable users can be easily exploited.Mr Preecha said: "Home surfers have a huge amount of personal information on their PCs. Every time they shop online, they are transferring that information across cyberspace. If they are using an unprotected Wi-Fi connection, rogue users within signal range can surf the net at the expense of someone else's phone bill. This may seem fairly harmless, but it can have a dramatic effect on your surfing speed. But worse, experienced hackers can gain access to your data, files, personal information and more, without you noticing."He warned that having up-to-date antivirus software and a firewall is also vital to prevent.Your computer from being disabled by viruses and spyware programmes that can reveal what you do on the internet. Mr Preecha explained: "Many users already have viruses and spyware on their PCs but are unaware that they are open to attack. Protecting yourself from these problems is really simple. Most home users just need their security settings enabled on equipment they already own.
