A type of cable that consists of two independently insulated
wires twisted around one another. The use of two wires twisted
together helps to reduce crosstalk and electromagnetic induction.
While twisted-pair cable is used by older telephone networks and is
the least expensive type of local-area network (LAN) cable, most
networks contain some twisted-pair cabling at some point along the
network. Other types of cables used for LANs include coaxial cables
and fiber opticcables.
