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.
