Easy Steps to Build You Own Quad Core Computer

30 06 2008

What is Quad Core Computer? Quad Core computer is essentially a speed demon that allows its user to play high-end video games, run computer programs, and rip DVDs at the same time! The second generation quad core processor offers multitasking performance with greater energy efficiency. The performance that you get is that of 4 CPUs. Dominating the work of CPU on a single core the quad core CPU allows multi-tasking more easily. The high performance infrastructure application can maximize the virtualization efforts with efficiency. However, the high potential computing power of the processor with four cores can be gained by the use of software that is coded to be multi threaded. The brilliant concept of the software helps the processor work efficiently along with virtually increasing the running speed of the programs. How to create your own QC Computer: Buying a Quad Core Computer could be expensive; however, if you are running low on your budget you could build your own quad core computer for less than you can imagine. All you have to do is choose the essential components fit them in your existing PC to realize the speed and your dream QC computer. Here is what you have to buy for turning your home PC into a quad core speed demon. Motherboard: The choice of motherboard depends on certain things such as whether you choose an Intel or an AMD processor, or what type of graphics cards you use. You need to decide on a motherboard on the basis of your requirements. CPU: When it comes to the CPU, you are left with two choices, i.e., Intel Version and AMD Version. If you want to go economical, AMD Phenom 9500 can help you save some money which can invest in good graphics cards. Memory: Choosing the memory is a tad bit tough as you have to balance between price, quality and speed. You can go either with Patriot DDR2-1066 or choose DDR2-800 OCZ Gold Edition RAM which is available in a dual channel 2GB kit. Hard Drive: Hard Drive decides speed of a quad core computer. While choosing hard drives, focus more on the speed factor than size. You can count on 250GB SATA2 Seagate drive. It won’t let you down. Video Card: You can’t imagine a gaming rig without good video cards. Whether you choose nVidia or ATI, both offer excellent options. If you want to maintain a perfect balance between price and performance, Saphire Radeon 3870 with 512MB of video memory could do the trick for you. DVD Drive: Choose a burner that works well for you. Since they are not too costly, you shouldn’t hesitate to invest in a good DVD drive for your self-made quad core computer. Case and PSU: Choose a case that will endure load and allow air out of it. The good news is most of the cases come with a power supply. Also look at the cooling feature as well. You can go with the Antec Sonata III case that is available with an Earthtech 500 Watt PSU. Cables: Usually, cables come with the motherboard. However, you can check the manufacture’s website to be sure if they are a part of the motherboard box. In case you don’t find cables in the box, you might need an IDE cable for your DVD drive and also SATA cables for each hard drive. Windows Vista: It doesn’t really matter if you already have a home premium version, you would do well to order 64 bit version if you want to empower your quad core computer with 4GB RAM capacity.

What Is a Virus?

30 06 2008

Most viruses are written with a malicious intent, so that they can cause damage to programs and data in addition to spreading themselves. Viruses infect existing programs to alter the behavior of programs, actively destroy data, and perform actions on storage devices that render their stored data inaccessible.

Computer viruses attack the software of a computer such as operating systems, data files, application software, and e-mails. However, viruses do not affect the computer hardware.

Viruses infect computers and spread themselves using various methods. Some viruses attach themselves to a common program such as a popular game or word processor. When a person downloads the infected game and runs it, the attached virus program gets executed. The virus then loads itself into memory and searches for any other program on the disk. If the virus finds any program, it modifies the program by adding the malicious code to the program. The next time this program gets executed, it infects other programs, and the cycle continues thereafter.

There are many types of computer viruses such as a boot-sector virus, macro virus, e-mail virus, etc.

A boot-sector virus infects the boot record on hard disks and floppy disks, which is used to start the computer. When the computer is turned on or restarted, the virus is automatically executed. An infected boot disk may stop the computer from starting up.

A macro virus is a macro or script that attaches itself to a file or template. When the file is loaded, the instructions of the macro or script are executed.

An e-mail virus moves around in e-mail messages, and usually replicates itself by automatically mailing itself to many people in the their e-mail address book.

Some other types of programs are also harmful to computers, which are not viruses such as a Trojan horse.

The main difference between a virus and a Trojan horse program is that a Trojan horse program does not replicate itself. A Trojan horse only destroys information on the hard disk. A Trojan horse program disguises itself as a legitimate program such as a game or utility. It often looks and initially acts in the same way as a legitimate program, but when it is executed, it destroys or corrupts data. A Trojan horse program can contain viruses, but it is not a virus itself.

A Worm uses computer networks and security holes to replicate itself. A Worm scans the network for another computer that has a specific security hole. It copies itself to the new computer using the security hole, and then starts replicating from there as well. A virus can have both virus and worm characteristics.

There are several anti-virus software that can detect, identify, and remove these viruses. As a precaution against viruses, we should take the following actions:

An anti-virus software that can detect, identify, and remove viruses should be installed on the computer.
All information downloaded from the Internet or some unknown resource must be immediately scanned for viruses by using an anti-virus software.
Any e-mail attachment that comes from unknown sources should never be opened.
