The touchpad, a big space for the finger to scroll and two buttons for left and right clicking

A touchpad (also called a trackpad) is a type of input device for computers that does the same things as a computer mouse. It is made up of a flat, touch-sensitive surface which the user slides one or more fingers on to move the cursor on the screen. Next to the touchpad are push-buttons that work just like mouse buttons, including left-clicking and right-clicking. In some newer touchpads, there are no actual buttons, and clicking is done by pushing near the button of the touchpad itself.
