Internet/Print Server User’s Guide

B

Bandwidth	The range of frequencies available across a
	communications channel; in one sense, the
	“size” or “speed” of the communications
	channel.
C
Category 3, 4, 5	Communication cabling standards referring
	to the quality of the transmission medium
	and whether or not the cable includes
	transmission shielding.
Collision	Simultaneous data transmission on a net-
	work medium, resulting in a garbled (and
	unreadable) transmission. See “CSMA/CD.”
Collision Domain	A section of a network isolated from other
	sections by a switch, bridge, or hub that de-
	tects and resolves collisions locally so that
	there is less impact on the entire network.
CSMA/CD	Carrier Sense Multiple Access with Colli-
	sion Detection; a network communications
	protocol in which each transmission source
	(i.e., station, server, switch, etc.) monitors
	the main data channel for traffic before and
	during transmission, postponing transmis-
	sion when the data channel is in use.
D
DHCP	Dynamic Host Configuration Protocol.
	DHCP is a protocol that allows IP addresses
	to be dynamically assigned as computers are
	turned on.
