                           Input                 Output                      Processing
                    A computer is an electronic device that processes information, so it is also called an
                    information processor. The information is stored in its memory and processed to bring
                    results. When a computer shows the result of the data processing on the monitor, it is
                    called output. Thus, a computer works by combining the input, storage, processing and
                    output. All the main parts of a computer system are involved in one of these four pro-
                    cesses.
                    Keyboard

                    The computer keyboard looks like a typewriter. It uses an arrangement of buttons or keys
                    that have characters engraved or printed on them. Each press of a key corresponds to a
                    single written symbol.

                    You can type text and numbers with the keyboard. The keyboard is also used for
                    computer gaming. It is used to give commands to the operating system of a computer, so
                    it is an input device.
