Topology - A network's topology is a logical characterization of how the

devices on the network are connected and the distances between them. The

most common network devices include hubs, switches, routers, and gateways.

Most large networks contain several levels of interconnection, the most impor-

tant of which include edge connections, backbone connections, and wide-area

connections.

USB (Universal Serial Bus) - A "plug and play" interface between a computer

and add-on devices (such as audio players, joysticks, keyboards, telephones,

scanners, and printers). With USB, a new device can be added to your comput-

er without having to add an adapter card or even having to turn the computer

off. The USB peripheral bus standard was developed by Compaq, IBM, DEC,

Intel, Microsoft, NEC, and Northern Telecom and the technology is available

without charge for all computer and device vendors.

USB supports a data speed of 12 megabit per second. This speed will accom-

modate a wide range of devices, including MPEG video devices, data gloves,

and digitizers. It is anticipated that USB will easily accommodate plug-in tele-

phones that use Integrated Services Digital Network and digital private branch

exchange.

Since October, 1996, the Windows operating systems have been equipped with

USB driver or special software designed to work with specific I/O device types.

USB is integrated into Windows 98. Today, most new computers and peripher-

al devices are equipped with USB.

A different "plug-and-play" standard, Firewire/IEEE 1394, is designed to sup-

port much higher data rates and devices such as video camcorders and digital

video disk (digital versatile disk) players. Both standards are expected to exist

together, serving different device types.

UTP - Unshielded twisted pair is the most common kind of copper telephone

wiring. Twisted pair is the ordinary copper wire that connects home and many

business computers to the telephone company. To reduce crosstalk or electro-

magnetic induction between pairs of wires, two insulated copper wires are

twisted around each other. Each signal on twisted pair requires both wires.

Since some telephone sets or desktop locations require multiple connections,

twisted pair is sometimes installed in two or more pairs, all within a single

cable.

Workgroup - Two or more individuals that share files and databases.
