O The mouse is the most common pointing device for a desktop computer.  O It typically rests on a flat surface close to the computer, and it is moved in the appropriate direction to point to and select objects on the screen.  O As it moves, an on-screen mouse pointer moves accordingly. O Once the mouse pointer is pointing to the desired object on the screen, the buttons on the mouse are used to perform actions on that object. O Similar to keyboards, mice today typically connect via a USB or mouse port, or via a wireless connection.
