Glossary of Terms
Twisted-Pair Cable:
Inexpensive, multiple-conductor cable comprised of one or more pairs of 18 to 24 gauge copper
strands. The strands are twisted to improve protection against electromagnetic and radio frequency
interference. The cable, which may be either shielded or unshielded, is used in low-speed
communications, as telephone cable. It is used only in baseband networks because of its narrow
bandwidth.
Unix:
A multitasking, multiuser computer operating system developed by AT&T. Several versions exist, e.g.,
the Berkeley version.
UTP:
Unshielded twisted pair, one or more cable pairs surrounded by insulation. UTP is commonly used as
telephone wire.
Wide Area Network (WAN):
A network using common carrier transmission services for transmission of data over a large
geographical area.
Workgroup Switching:
Configuration in which a number of users are connected to an Ethernet network via a switch.
Switching allows each user to get greater throughput than would be available through a hub.
X.25 Gateway Access Protocol:
Allows a node not directly connected to a public data network to access the facilities of that network
through an intermediary gateway node. X.25 is the protocol standard governing packet-switched
networks.
