A mouse and a keyboard are the important parts of a computer. A mouse
                  is an input device, used to select an object on the monitor. When we move a

                  mouse, an arrow-like pointer displayed on the monitor also moves. First, let us
                  learn about the mouse.




                            TYPES OF MOUSE


                  The different types of the computer mouse are:


                  OPTICAL MOUSE

                  An optical mouse is the most commonly used mouse. It uses
                  laser light to help in moving the pointer on the screen.



                                       GAMING MOUSE

                                       A gaming mouse is generally used to play games. It is similar

                                       to a scroll mouse but works much faster.




                  WIRELESS MOUSE


                  A wireless mouse connects to the computer without a wire. It is also
                  known as a  cordless  mouse. It uses  wireless technology  to  send

                  signals to the computer and helps it work.



                            ACTIONS OF A MOUSE


                  A mouse is used to perform various actions.


                  SINGLE-CLICK OR LEFT-CLICK

                  To left-click a mouse, press the left mouse

                  button  once and then release it.  Doing this
                  makes a clicking sound. This action is called                  Click

                  clicking and it is done to select an item on the
                  screen.
