Glossary

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-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, or 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
