Single Standard Function Ports

Standard Single-Function Ports

Every PC sports several single-function ports for connecting peripherals such as keyboards, monitors, and the like. With only a couple of exceptions, these standard ports support only a single type of device

The Keyboard Port

Keyboards come in a variety of styles, from the plain-Jane, rectangular typewriter substitute to the exotically curved, multi-function gadget that’s bristling with special function hot keys

and equipped with ports of its own. Regardless of their appearance, however, all keyboards enable you to do one thing—enter commands into your PC. Modern PCs have a purple 6-pin mini-DIN (commonly called a PS/2 connector) port . The mini-DIN port is keyed so you can insert the keyboard connector only one way.
