channel, in terms of how much data the facility can transmit in a fixed
amount of time; expressed 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.
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
computers 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 control to it.
Bottleneck – A traffic slowdown that results when too many network
nodes try to access a single node, often a server node, at once.
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.
Browser - A browser is an application program that provides a way to look
at and interact with all the information on the World Wide Web or PC. The
word "browser" seems to have originated prior to the Web as a generic
