                  You have already learnt that the mouse is an input device. Let us 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
                     TYPES OF MOUSE

                  There are many types of computer mouse, such as:

                  Ball Mouse


                  A ball mouse has a hard rubber ball inside it, that helps it move
                  on the screen. It is rarely used now. The ball catches dust easily,
                  which can cause the mouse to stop working properly.

                                   Optical Mouse

                                   The  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


                  The wireless mouse has no wire. It runs on batteries and is attached
                  to the computer through Bluetooth. It is also an optical mouse.
