A pointing device is an external component that lets the user control the free planar movement of an on-screen icon, usually an arrow. While not an absolutely essential computer component, a pointing device greatly eases the navigation of graphical interfaces including Windows 9x and Windows applications, and is therefore included with almost every computer.

An upgrade should be considered if the present pointing device is uncomfortable, frustrating to work with, or does not move the on-screen pointer effectively.

There are many different types of pointing devices available, including mice, trackballs, touchpads, and eraserheads. All have at least two function buttons, and some newer mice include a wheel between the buttons for scrolling. Many devices have third or even fourth buttons that can be programmed for different specialized functions or routines. Most mice are usually designed for either right-handed or left-handed people. Pointing devices connect to the computer using either a serial or PS/2 port.

When purchasing a pointing device, make sure that it is of the compatible hardware interface, that it is comfortable, and that you can accomplish your pointing tasks quickly and with ease. Pointing devices range in cost from $15 to $100.

It takes about 2 minutes to install a new pointing device. No tools are needed.
