Summary

Introduction to Computers. Computer studies form one topic one.

Brief Overview:

Definition of a Computer:

An electronic device that accepts data as input, and transforms it under the influence of a set of special instructions called Programs, to produce the desired output (referred to as Information).


Explanations;

- A computer is described as an electronic device because; it is made up of electronic components and uses electric energy (such as electricity) to operate.

- A computer has an internal memory, which stores data & instructions temporarily awaiting processing, and even holds the intermediate result (information) before it is communicated to the recipients through the Output devices.

- It works on the data using the instructions issued, means that, the computer cannot do any useful job on its own. It can only work as per the set of instructions issued.

A computer will accept data in one form and produce it in another form. The data is normally held within the computer as it is being processed.
