B
Bandwidth
The range of frequencies available across a
communications channel; in one sense, the
“ size” of the communications channel.
BOOTP
The BOOTstrap Protocol, a method network de-
vices can use to obtain TCP/IP configuration
information from a central location on startup.
Bridge
A LAN device used to connect two different
LANs so that packets can be transmitted from
one to the other. A bridge works on a low level,
and does not take higher-level protocols into
consideration. In this document and the hub
management software, switching modules are
most often referred to as bridges.
C
Cascading
The practice of connecting identical or similar
LAN devices such as hubs together directly so
that they function as one device. A collection of
cascaded devices is often called a stack.
Category 3, 4, 5
Communication cabling standards referring to
the quality of the transmission medium and
whether or not the cable includes transmission
leakage shielding.
Collision
Simultaneous data transmission on a network
medium, resulting in a garbled (and unreadable)
transmission. See “ CSMA/CD.”
Collision Domain
A section of a network isolated from other sec-
tions by a switch, bridge, or hub that detects and
resolves collisions locally so that there is less
impact on the entire network.
