IEEE 802.3ab specification for Gigabit Ethernet over
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
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.
