10BASE-TIEEE 802.3 specification for 10 Mbit/sec Ethernet over two pairs of Category 3, 4, or 5 UTP cable.

100BASE-TXIEEE 802.3u specification for 100 Mbit/sec Fast Ethernet over two pairs of Category 5 UTP cable.

1000BASE-TIEEE 802.3ab specification for Gigabit Ethernet over two pairs of Category 5, 5e 100-ohm UTP cable.

1000BASE-XIEEE 802.3 shorthand term for any 1000 Mbit/sec Gigabit Ethernet based on 8B/10B signaling.

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.

Bandwidth

Utilization The historical percentage of packets received as compared to total bandwidth.

BOOTP Boot protocol used to load the operating system for devices connected to the network.

Auto-negotiationSignalling method allowing each node to select its optimum operational mode (for example, 10, 100, or 100 Mbit/sec and half or full duplex) based on the capabilities of the node to which it is connected.

Collision A condition in which packets transmitted over the cable interfere with each other. Their interference makes both signals unintelligible. This only applies to half-duplex connections.

Collision Domain Single CSMA/CD LAN segment.

CSMA/CD Carrier Sense Multiple Access/Collision Detect is the communication method employed by Ethernet and Fast Ethernet.
