D-Link DFE-2600 manual Crossover Cable, Csma/Cd, Duplex full & half, Fast Ethernet, Glossary

Crossover Cable	A type of twisted-pair cable in which the wires at
	one end have been reversed in order to match
	pinouts on a hub or switch.
CSMA/CD	Carrier Sense Multiple Access with Collision De-
	tection; a network communications protocol in
	which each transmission source (i.e., station,
	server, switch, etc.) monitors the main data chan-
	nel for traffic before and during transmission,
	postponing transmission when the data channel is
	in use.
D
Duplex (full & half)	The transmission of data over a network in both
	directions. Full-Duplex (FDX) is simultaneous
	transmission of data over a network channel in
	both directions. Half-Duplex (HDX) is transmis-
	sion in both directions but one at a time, not
	simultaneous.
E
Ethernet	A particular type of LAN described in a standard
	(802.3) established by the IEEE, with 10Mbps
	data transmission.
F
Fast Ethernet	An extension of Ethernet LAN (defined in stan-
	dard 802.3u) to allow 100Mbps transmissions.
H
Hub	The central device in a star-topology LAN used to
	connect each station to the network.
