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-
negotiation
Two-part process by which a network device automatically senses the speed and duplex
capability of another 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
Cable made of thin glass threads that carry data in the form of light pulses.
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-
forward
Switching feature where the port receives the entire incoming frame and stores it in the
buffers while checking for 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
individual 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 packets per second using 1,518-byte frames.
