COMPLIANCES
10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two
pairs of Category 3, 4, or 5 UTP cable
100BASE-TX
IEEE 802.3u specification for 100 Mbps Ethernet over two
pairs of Category 5 UTP cable.
1000BASE-LH
Specification for long haul Gigabit Ethernet over two
strands of 9/125 micron core fiber cable
1000BASE-LX
IEEE 802.3z specification for Gigabit Ethernet over two
strands of 50/125, 62.5/125 or 9/125 µm core fiber cable.
1000BASE-SX
IEEE 802.3z specification for Gigabit Ethernet over two
strands of 50/125 or 62.5/125 micron core fiber cable.
1000BASE-T
IEEE 802.3ab specification for Gigabit Ethernet over 100-
ohm Category 5, 5e or 6 twisted-pair cable (using all
four-wire pairs).
AUTO-
NEGOTIATION
Signaling method allowing each node to select its
optimum operational mode (e.g., speed and duplex mode)
based on the capabilities of the node to which it is
connected.
BANDWIDTH
The difference between the highest and lowest
frequencies available for network signals. Also
synonymous with wire speed, the actual speed of the
data transmission along the cable.
COLLISION
DOMAIN
Single CSMA/CD LAN segment.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision
Detect) is the communication method employed by
Ethernet, Fast Ethernet, and Gigabit Ethernet.
END STATION
A workstation, server, or other device that does not
forward traffic.
ETHERNET
A network communication system developed and
standardized by DEC, Intel, and Xerox, were using
baseband transmission, CSMA/CD access, logical bus
topology, and coaxial cable. The successor IEEE 802.3
standard provides for integration into the OSI model
and extends the physical layer and media with repeaters
and implementations that operate on fiber, thin coax
and twisted-pair cable.
FAST ETHERNET
A 100 Mbps network communication system based on
Ethernet and the CSMA/ CD access method.
