Characteristics of Computers

Computers have the following characteristics.

Speed

A computer is a very fast device. Computer makes calculations at an amazing speed without any mistakes. Even a microcomputer can make as many calculations in one minute that may take the entire life of a scientist or an engineer. A modern computer can execute several millions of instructions per second (MIPS). The speed of a computer is usually measured in microseconds, nanoseconds and pico seconds.

Accuracy

The accuracy of a computer is consistently high and the degree of accuracy of a particular computer depends upon its design. Error can occur in a computer, but these are mainly man-made, such as inaccurate data and imprecise thinking of programmer rather than technical weakness.

Diligence

Unlike human being, a computer is capable of performing almost any task provided that the task can be reduced to a series of steps.

Versatility

A computer is capable of performing almost any task provided that the task can be reduced to a series of logical steps.

High Storage Capacity

Computers can store large amount of data and information in a very small space and any part of it can be retrieved as and when required, in a microsecond or even less.

Reliability

Computers are designed in such a way that their individual components have very high life and degree of reliability. Computer makes calculations without tiring and making any mistakes.

No Intelligence

Computers possess no intelligence of their own. They have to be told what to do and in what sequence. Computers cannot make any judgement of their own. Their judgement is based on the instructions given to them in the form of programs.
