Basic functions of a computer.

Five basic functions can be identified which are done by the computer. Those are;

 1 . Input or inserting data and instructions.

 2 . Processing.

 3 . Output or retrieving data and information.

 4 . Storing data or information.

 5 . Controlling.

1 . Input or inserting data and instructions.

                  Input can be defined as inserting data and instructions needed for a computer.

2 . Processing.

 

             The process of converting data inserted to the computer to information as required can be defined as processing.

3 . Output or retrieving data and information.

               Giving the processed data and information to the external forces is done under output.

4 . Storing data or information.

Data and information are stored in a way that those can be reused later as required. This is done under storing.

5 . Controlling.

The process of  a computer system should be controlled properly. This controlling done to a computer system is considered here.
