Twisted pair cable is a type of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from Unshielded Twisted Pair (UTP) cables, and crosstalk between neighboring pairs.
a).It is a thin, flexible cable that is easy to string between walls.
b).Because UTP is small, it does not quickly fill up wiring ducts.
c).UTP costs less per meter/foot than any other type of LAN cable
