                  PROCESSING DEVICE

                  A processing device usually works on the input. CPU

                  is the processing device of a computer. CPU stands
                  for Central Processing Unit.


                  OUTPUT DEVICES                                                             CPU         CPU box


                  Output devices show the result of all the work done on the input. The result is

                    ▶   A computer works in three steps: input, process and output.

                    ▶   Input devices give instructions to the computer.
                    ▶   Processing device works on input.

                    ▶  Output devices show the result of all the work done on the input.
