Computers are capable of doing more things every year. There are many advantages toknowing how to use a computer, and it is important that everyone know how to use themproperly. Using the information I have gathered, and my own knowledge from my 12 years ofcomputer experience, I will explain the many advantages of owning a computer and knowing howto use a PC and I will attempt to explain why you should purchase a computer and learn how touse one properly.Webster's New World Compact Dictionary defines a computer as 'an electronic machine thatperforms rapid, complex calculations or compiles and correlates data' ('Computer.'). While thisdefinition gives one a very narrow view of what a computer is capable of doing, it does describethe basic ideas of what I will expand upon. We have been living through an age of computers for ashort 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 250million Personal Computers (PC's) were in use by 1995, and one out of every three homes had aPC (Shelly, Cashman,& Waggoner, 138).Computers are easy to use when you know how they work and what the parts are. Allcomputers 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 systemsconsist of a monitor, a system unit which contains the Central Processing Unit (CPU), afloppy-disk drive, a CD-ROM drive, speakers, a keyboard, a mouse, and a printer. Eachcomponent takes a part in one of the four operations.The keyboard and mouse are input devices that a person uses to enter data into the computer.From there the data goes to the system unit where it is processed into useful information thecomputer can understand and work with. Next the processed data can be sent to storage devicesor to output devices. Normally output is sent to the monitor and stored on the hard-disk or to afloppy-disk located internal of the system unit.
