35
IEEE 802.3z specification for Gigabit Ethernet over two strands of 50/125,
62.5/125 or 9/125 micron core fiber cable.
1000BASE-LH
Specification for long-haul Gigabit Ethernet over two strands of 9/125 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
Signalling 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
A condition in which packets transmitted over the cable interfere with each other.
Their interference makes both signals unintelligible.
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, 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.
Gigabit Ethernet
A 1000 Mbps network communication system based on Ethernet and the
CSMA/CD access method.
Full Duplex
Transmission method that allows two network devices to transmit and receive
concurrently, effectively doubling the bandwidth of that link.
IEEE
Institute of Electrical and Electronic Engineers.
IEEE 802.3
Defines carrier sense multiple access with collision detection (CSMA/CD) access
