                       All the physical components of a computer system are called hardware.
                       A computer accepts data and instructions through input devices.
                        A computer  converts the input into meaningful information through  the
                       processing device.

                        A computer displays the results of the processed data through the output
                       devices.
                        When you have finished working with your data, you can store it permanently
                       on storage devices.

                        Stepwise instructions are  called software.  There  are  mainly two  types of
                       software: System software and Application software.
                        System software controls and manages the overall activities of a computer
                       system.
                       Application software is used to perform a specific task.

                        Microcomputers,  Minicomputers, and Supercomputers  are  the  different
                       types of computers.
