Backbone – The part of a network that connects most of the systems and net-
works together and handles the most data.
Bandwidth – 1. Measure of the information capacity of a transmission channel,
in terms of how much data the facility can transmit in a fixed amount of time; ex-
pressed in bits per second (bps). 2. The difference between the highest and lowest
frequencies of a band that can be passed by a transmission medium without undue
distortion, such as the AM band 535 to 1705 kilohertz.
Baseband - Transmission scheme in which the entire bandwidth, or data-carrying
capacity, of a medium (such as a coaxial cable) is used to carry a single digital pulse,
or signal, between multiple users. Because digital signals are not modulated, only
one kind of data can be transmitted at a time. Contrast with broadband.
Baud (Bite at Unit Density) - A measure of the speed of transmission of data;
number of elements transmitted per second.
Beacon Interval - The frequency interval of the beacon, which is a packet broad-
cast by a router to synchronize a wireless network.
Bit – A binary digit. The value—0 or 1—used in the binary numbering system. Also,
the smallest form of data.
Boot – To cause the computer to start executing instructions. Personal comput-
ers contain built-in instructions in a ROM chip that are automatically executed on
startup. These instructions search for the operating system, load it, and pass con-
trol to it.
Bridge/Router- A device that can provide the functions of a bridge, router, or
both concurrently. Bridge/router can route one or more protocols, such as TCP/IP
and/or XNS, and bridge all other traffic.
Broadband - A data-transmission scheme in which multiple signals share the
bandwidth of a medium. This allows the transmission of voice, data, and video
signals over a single medium. Cable television uses broadband techniques to deliver
dozens of channels over one cable.
Broadcast Domain - Defines the set of all devices which will receive broadcast
frames originating from any device within the set. Broadcast domains are normally
bounded by routers.
