Cable made up of a pair of insulated copper wires wrapped around each other to cancel the effects of electrical noise.
Twisted pair is two separately charged wires twisted around each other. One wire carries the electrical signal and the other is the ground. This is common for phone lines and inexpensive LANs. The reason the wires are twisted around each other is to reduce "crosstalk", which is electrical interference generated by the two wires. This results in noise (crosstalk) being carried evenly by the two wires in the pair, which causes the noise to cancel itself out. Generally more than one pair is contained within a cable. For example, the phone company may run 2 or 4 pairs to an apartment to allow for additional lines being installed at a future date. There are specific standards for making twisted pairs. In general, the higher the transmission rate across the wire the more strict the standard. This standard includes gauge (the diameter of the wire), how the wire is twisted and the number of twists per foot. Twisted pair comes in two forms: shielded, which has an electromagnetic shield around the pairs, and unshielded, which does not.

Twisted pair cabling refers to a cable constructed of 2 braided wires, each with its own dielectric insulation twisted together to form a single cable. The twisting allows the cable to carry higher frequency signals than the cable could otherwise.

There are 2 basic types of twisted pair cables: Shielded and unshielded. Most applications in the home use unshielded 4 pair cable.

In the telecommunications industry, wire is usually referred to in pairs rather than conductors. With the introduction of data transmissions, crosstalk (interference between individual conductors) became problematic. The fix is called Twisted Pair. This refers to individual pairs of wire that are twisted randomly. The twists create an inconsistent, ever changing EMF (ElectroMagnetic Field), thus preventing crosstalk. This novel concept eliminates the need for shielding and is also referred to as UTP, or Unshielded Twisted Pair.
