1 Answer

Answer :

 Input Operation:

 A computer works in the light of instructions (input) given to it.

 Input is given by a user using keyboard or mouse.

 The input is stored in memory for further processing.

 Processing Operation:

 Microprocessor processes the data according to instructions (input).

 Microprocessor fetches the data from memory and Control Unit (CU) decodes the instructions.

 After decoding, it sends signals to other parts of computer to execute it.

 Storage Operation:

 The result produced after processing are stored in memory before sending to output device or hard disk.

 Output Operation:

 The Control Unit displays the results on the monitor or print it on paper. Results can also be saved on hard disk for future use.
