Definition - What does Trackball mean?
There are usually one or two buttons provided with a trackball that have the same capability as click buttons on a mouse. Unlike other input devices which needs movement like the mouse, a trackball is stationary and does not require much space. It can also work on most surfaces which is a great advantage compared to other input devices.
