GLOSSARY

10BASE-T

IEEE specifications for 10 Mbps Ethernet on twisted-pair cable (100 Ω UTP). The maximum cable length for a point-to-point connection is 100 m (328 ft.) and the maximum number of nodes is 1024.

10BASE2

IEEE specifications for 10 Mbps Ethernet on thin coaxial cable (50 Ω RG-58). A cable segment can be up to 185 m (607 ft.) long and have a maximum of 30 nodes.

10BASE5

IEEE specification for 10 Mbps Ethernet on thick D-type cable. A cable segment can be up to 500 meters and have a maximum of 100 nodes.

AUI (Attachment Unit Interface)

A 15-pin logical, electrical and mechanical interface specified by the IEEE 802.3 standard for connecting a PC, server or other device to an Ethernet transceiver or Media Access Unit (MAU).

BNC

Connector with a half-twist locking shell typically used for thin coaxial cable.
