COMPUTER FUNDAMENTALS

Detailed explanation-1: -The twisted-pair cable was primarily developed for computer networks. This cable is also known as Ethernet cable. Almost all modern LAN computer networks use this cable. This cable consists of color-coded pairs of insulated copper wires.

Detailed explanation-2: -A twisted pair cable comprises two separate insulated copper wires, which are twisted together and run in parallel. The copper wires are typically 1mm in diameter. One of the wires is used to transmit data and the other is the ground reference.

Detailed explanation-3: -Unshielded twisted pair or UTP: UTP cable has four pairs or eight colour-coded copper wires twisted together and covered with a plastic sheath. Their electromagnetic interference gets cancelled due to the twisting effect. UTP cables are primarily used in LANs, telephone wires and ethernet cables.

Detailed explanation-4: -Unshielded twisted pair (UTP) cables are found in many Ethernet networks and telephone systems. For indoor telephone applications, UTP is often grouped into sets of 25 pairs according to a standard 25-pair color code originally developed by AT&T Corporation.
