1 Using a USB device

Universal Serial Bus (USB) is a hardware interface that can be used to connect an optional external device, such as a USB keyboard, mouse, drive, printer, scanner, or hub, to the computer or to an optional expansion product. A hub provides additional USB ports for the system and can be connected to the computer or to another hub.

Depending on the computer model, the computer has 2 or 3 standard USB ports. An optional expansion product provides additional USB ports that can be used with the computer. The USB ports on the computer support USB 1.0, USB 1.1, and USB 2.0 devices.

NOTE Your computer may look slightly different from the illustrations in this chapter.
