Computer mice come in many shapes and sizes but are all designed to fit either the left or right hand. Anywhere from one to six or more buttons and often a scroll wheel are integrated onto the mouse to provide a wide variety of functions.

Mice may be wired or wireless but they always communicate with the computer via PS2 or USB ports, usually located on the motherboard. Even though the mouse sits outside the main computer housing, it is an essential part of the complete system.
