Computers are capable of doing more things every year. There are many advantages to

knowing how to use a computer, and it is important that everyone know how to use them

properly. Using the information I have gathered, and my own knowledge from my 12 years of

computer experience, I will explain the many advantages of owning a computer and knowing how

to use a PC and I will attempt to explain why you should purchase a computer and learn how to

use one properly.

Webster's New World Compact Dictionary defines a computer as 'an electronic machine that

performs rapid, complex calculations or compiles and correlates data' ('Computer.'). While this

definition gives one a very narrow view of what a computer is capable of doing, it does describe

the basic ideas of what I will expand upon. We have been living through an age of computers for a

short while now and there are already many people world wide that are computer literate.

According to Using Computers: A Gateway to Information World Wide Web Edition, over 250

million Personal Computers (PC's) were in use by 1995, and one out of every three homes had a

PC (Shelly, Cashman,& Waggoner, 138).

Computers are easy to use when you know how they work and what the parts are. All

computers perform the four basic operations of the information processing cycle: input, process,

output, and storage. Data, any kind of raw facts, is required for the processing cycle to occur.

Data is processed into useful information by the computer hardware. Most computer systems

consist of a monitor, a system unit which contains the Central Processing Unit (CPU), a

floppy-disk drive, a CD-ROM drive, speakers, a keyboard, a mouse, and a printer. Each

component takes a part in one of the four operations.
