                  Mouse


                  A mouse is an important part of a computer. It is a pointing device. The mouse helps
                  us to tell the computer what to do.

                  The other uses of a mouse are:
                     to draw pictures.

                     to play games.
                     to give commands to the computer.

                     to point different things with the help of a pointer on the screen.
