                     PROCESS


                 After  receiving  the  input,  the  computer
                 performs  action  on  it  with  the  help  of  the
                 Central Processing Unit (CPU).  CPU  is  fixed
                 inside the CPU box/cabinet. The CPU is known
                 as the brain of the computer and performs all
                 the calculations.                                              CPU Box/cabinet             CPU


                     OUTPUT


                 Output is the result that we get after processing. Monitor and printer are examples
                 of output devices. A monitor shows the output on the screen, and a printer provides
                 the output on paper.
