Computer Parts

A computer is a machine for manipulating data according to a list of instructions. The parts of a computer you can touch, such as the monitor or the central processing unit (CPU) are hardware. All hardware except the CPU and the working memory are called peripherals. Computer programs are software. The operating system (OS) is software that controls the hardware. Most computers run the Microsoft Windows OS. MacOS and Linux are other operating systems.

The CPU controls how fast the computer processes data or information. We measure its speed in megahertz (Mhz) or gigahertz (Ghz).The higher the speed of the CPU, the faster the computer will run. We measure the random access memory (RAM) of the computer in megabytes (MB). RAM controls the performance of the computer when it is working and moves data to and from CPU. Programs with a lot of graphics need a large RAM to run well. The hard disk stores data and software programs. We measure the size of the hard disk in gigabytes (GB).

How can you protect your computer? Don't worry too much about viruses. You may never see one. There are just a few ways to become infected that you should be aware of. The sources can be service people, pirated games, putting floppies in publicly available PCs without write-protected tabs¹. Carry a virus-checking program and scan the PC before letting it write data onto floppies. There are actually two kinds of antivirus programs: virus shields, which detect viruses as they are infecting your PC, and virus scanners, which detect viruses once they've infected you. Viruses are something to worry about, but not a lot. A little common sense and the occasional virus scan will keep you virus-free.

Ways to prevent infecting of your computer:

· don’t use pirated software

· don’t forget to update your antivirus program regularly

· don’t surf the Internet in case antivirus program is not installed.

Note:
