A mouse (Figure 7) is a pointing device that fits comfortably under the palm of your hand.
With a mouse, you control the movement of the pointer , often called the mouse pointer ,on the
screen and make selections from the screen. A mouse has one to five buttons. The bottom of a
mouse is flat and contains a mechanism (ball, optical sensor, or laser sensor) that detects
movement of the mouse.
Most notebook computers come with a touchpad, a small, flat, rectangular pointing device near
the keyboard that allows you to move the pointer by sliding a fingertip on the surface of the pad
(Figure 8). Notice in Figure 8 that the notebook computer has the keyboard built into the unit.
