                              Functions of the Mouse Buttons





                  You have already learnt that the mouse is an input device.
                  Let’s learn about the types of mouse and the functions of
                  a mouse. A mouse is a pointing device. It displays an arrow
                  on the screen, known as a pointer (            ).                               Computer mouse



                   i +   TYPES OF MOUSE

                  There are different types of computer mouse, for example:

                  Ball Mouse

                  A Ball Mouse has a hard rubber ball under it. It is rarely used
                  now because the ball catches dust easily, which causes the
                  mouse to stop working properly.



                                            Optical Mouse
                                            An Optical Mouse is used the most. It has an LED sensor at

                                            its bottom that helps the pointer on the screen to move. If
                                            you pick up the mouse, you will see a red light glow under it.

                  Wireless Mouse

                  A Wireless Mouse has no wire. It runs on batteries and connects to
                  the computer through Bluetooth. It is also an optical mouse.
