Terminologies and Abbreviations


ATM
Asynchronous Transfer Mode - High-speed transmission technology suitable for voice, data and video.
Backbone
A high-speed line or series of connections that forms a major pathway within a network.
bps

Ethernet
A very common protocol of networking computers in a LAN that operates over twisted-pair or coaxial cable at 10 Mbps. Fast Ethernet is a 100 Mbps implementation of the Ethernet standard.
FDDI
Fiber Distributed Data Interface - A standard for transmitting data on optical fiber cables at a rate of around 100 Mbps. ie: the campus FDDI ring
FDDI site
There are 8 sites on the campus FDDI ring. Each site consists of 4 main parts: a patch panel, a UPS (Uninterupted Power Supply), an FDDI router, and an FDDI concentrator, which explains why all the sites look basically the same.

T-1
A leased-line connection capable of carrying data at 1.544 Mbps.
TCP/IP
Transmission Control Protocol/Internet Protocol - The suite of protocols that defines the Internet.
Termserv
