Identifying Characteristics
of Ports and Cables
Now that you’ve learned the various types of items found in a computer, let’s discuss the
various types of ports and cables used with computers. A port is a generic name for any
connector on a computer into which a cable can be plugged. A cable is simply a way of
connecting a peripheral or other device to a computer using multiple copper or fiber-optic
conductors inside a common wrapping or sheath. Typically, cables connect two ports: one
on the computer and one on some other device.
Let’s take a quick look at some of the different styles of port connector types as well as
peripheral port and cable types. We’ll begin by looking at peripheral port connector types.
