Glossary

10BASE-T	Networking standard for twisted-pair cabling capable of carrying data at 10 Mbps.
100BASE-TX	Networking standard for two pairs of high -quality twisted-pair wires carrying data at 100 Mbps.
100BASE-FX	Networking standard for fiber-optic cabling capable of carrying data at 100 Mbps.
auto-	Two -part process by which a network device aut omatically senses the speed and duplex capability of another
negotiation	device.
Category 5	Networking standard certifying that a copper wire cable can carry data at up to 100 Mbps.
collision	Concurrent Ethernet transmissions from two or more devices on the same segment.
Ethernet	Networking standard for transmitting data at 10 Mbps.
Fast Ethernet	Networking standard for transmitting data at 100 Mbps.
fiber-optic	Cable made of thin glass threads that carry data in the form of light pulses.
cable
full-duplex	A communications technique that allows bi-directional, simultaneous transmission between two devices on a single
	segment.
half-duplex	A communications technique in which one device on a segment transmits while the other receives, then the process
	is reversed.
IEEE 802	Set of Institute of Electrical and Electronic Engineers standards for defining methods of access and control on
	LANs.
LAN	Local area network. A network where computers are connected in close proximity, such as in the same building or
	office park. A system of LANs connected at a distance is called a wide -area network (WAN).
MAC address	Media access control address. A hardware address that uniquely identifies each node of a network.
Mbps	Millions of bits per second.
segment	Section of a network bounded by bridges, routers, hubs, or switches. Dividing an Ethernet into multiple segments is
	a common way to increase bandwidth on a LAN.
store -and-	Switching feature where the port receives the entire incoming frame and stores it in the buffers while checking for
forward	runts and error frames before forwarding it to the destination port.
switch	Device that filters and forwards packets between LAN segments.
UTP	Unshielded twisted pair; cabling with wires that are twisted around each other. The indiv idual wires are not
	insulated.
wire speed	The ability to handle the fastest rate of traffic that a generator can deliver without dropping packets. On a 100 Mbps
	connection, wire-speed traffic is 148,809 packets per second using 64-byte frames or 8,127 packetspersecondusing
	1,518-byte frames.
