ring topology and a token passing access method.
Transceiver An AUI (Attachment Unit Interface) device for receiving and
transmitting data that often provides collision detection as well.
twisted pair cable A wiring scheme with one or more pairs of 18 to 24 gauge copper
strands are twisted to improve protection against electromagnetic
and radio frequency interference. Cable may be either shielded or
unshielded.
type 1 cable Shielded two-pair cable.
type 3 cable Unshielded twisted-pair cable.
type 5 cable Shielded twisted-pair cable.
WAN (Wide Area
Network) A network capable of transmissions over large geographic areas that
uses transmission lines provided by a common-carrier.
workstation A networked computer typically reserved for end-user applications.
