                        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.
