            PROCESSING DEVICE

            Processing device usually works on the input. A CPU

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

            Output devices show the result of all the work done on the input. The result is
            called the output. Some output devices are:

              ▶  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.
