Question 1

Describe twisted-pair cabling.

Accepted Answer

Twisted-pair cable is composed of small copper wires that are covered with an insulating material. Each wire is twisted with another, and this pair is color-coded. One wire is a solid color and the other is white with a stripe of the same solid color. One pair to four pairs of wires-each of a different solid color-are bundled together and encased in an outer jacket.
