Azimuth
This is the direction of antenna pointing relative to true north.
Band
A portion of the electromagnetic frequency spectrum.
Bandwidth
The range of frequencies over which a device will transmit information.
Bit
An abbreviation for binary digits.
Bit Error Rate
A measure of the number of errors in a digital transmission. Typically given as an exponential number that
represents the ratio of errors to total bits. Example: 1E-03 = 0.001 = 1.0 x 10-3 and 1.0E-6 = 0.000001
= 1.0 x 10-3. A single element in a binary code. A measure of the number of errors in a digital
transmission. Typically given as an exponential number that represents the ratio of errors to total bits.
Example: 1E-03 = 0.001 = 1.0 x 10-3 and 1.0E-6 = 0.000001 = 1.0 x 10-3.
Bridge
The function of a bridge is to connect separate networks together. This device operates at the DataLink Layer
of the OSI model. Bridges connect different network types (such as Ethernet and Token Ring) or networks of
the same type.
Byte
A data unit consisting of eight bits.
Cable
A transmission medium of copper wire or optical fiber wrapped in a protective cover.
Channel
A specific band of frequencies designated for a specific purpose; the data path between two nodes.
Classless Inter-Domain Routing (CIDR)
This is an abbreviated method of entering the netmask. For more information, see CIDR Table (For Netmask
Information Purposes) in Chapter 3.
