Identifying Characteristics of Ports and Cables 61
PS/2 (Keyboard and Mouse)
Another common port, as mentioned earlier, is the PS/2 port. A PS/2 port (also known as a
mini-DIN 6 connector) is a mouse and keyboard interface port first found on the IBM PS/2
(hence the name). It is smaller than previous interfaces (the DIN-5 keyboard port and serial
mouse connector), and thus its popularity increased quickly. Figure 1.43 shows examples of
both PS/2 keyboard and mouse ports. You can tell the difference because the keyboard port
is usually purple and the mouse port is usually green. Also, typically there are small graphics
of a keyboard and mouse, respectively, imprinted next to the ports.
