MOUSE POINTER

                  Just as we use our fingers to point at something, we use an arrow
                  to point at things we want to select on a computer. This arrow is
                  called the mouse pointer.

                  When we move the mouse, the mouse
                  pointer moves on the monitor in the                                Subject: Wireless Mouse

                  direction of the mouse. We can move                                A mouse that does not have
                  the mouse  accordingly  and point  at                              a wire is known as a wireless

                            PARTS OF A MOUSE


                  A mouse has mainly three parts. These are:


                  LEFT AND RIGHT BUTTONS

                  A mouse has two buttons. The button on the left is called the left button and
                  the button on the right is called the right button.                 Scroll Wheel
