Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet

CSMA/CD network access method.

Hub - The device that serves as the central location for attaching wires from

workstations. Can be passive, where there is no amplification of the signals; or

active, where the hubs are used like repeaters to provide an extension of the

cable that connects to a workstation.

Mbps (Megabits per second) - One million bits per second; unit of measure-

ment for data transmission.

MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port,

also known as an uplink port, connects to another hub or switch using a straight-

through cable. To connect a MDI port to a computer, use a crossover cable.

MDI-X (Medium Dependent Interface Crossed) - On a network hub or switch,

a MDI-X port connects to a computer using a straight-through cable. To con-

nect a MDI-X port to another hub or switch, use a crossover cable.

Network - A system that transmits any combination of voice, video and/or data

between users.

Switch - 1. A data switch connects computing devices to host computers, allow-

ing a large number of devices to share a limited number of ports. 2. A device for

making, breaking, or changing the connections in an electrical circuit.

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.

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 twist-

ed 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.
