IMPORTANCE OF THE COMPUTER AS A TOOL FOR DATA PROCESSING

The computer is a very unique electronic device and has certain features and characteristics that distinguish it from other machines. These include:

1. Speed – Computers are very fast; they can perform tens of millions of operations per second. This is necessary for predicting weather forecasts, performing scientific research and even producing thousands of bills for utility companies.
2. Accuracy – computers are very accurate. Errors only occur if there is an error in hardware, software or data. When errors occur it is usually because of some human error, since computers can only do what they are programmed to do.
3. Storing large amounts of information in a small space – there are many storage media that can be used to store large volumes of data and information. For example, a single CD-ROM disk can save the equivalent of a shelf of books in the library.
4. Working continuously – computers can work continuously for long periods without much maintenance.
5. Quality – The type of output produced by the computer is far better than other electronic machines. Document is best prepared by the use of the computers.
