FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Coaxial cable received its name because it includes one physical channel that carries the signal surrounded by another concentric physical channel, both running along the same axis. The innermost channel is typically a copper wire, which is then surrounded by a layer of insulation between it and the outer channel.

Detailed explanation-2: -Optic fiber cable can transmit data at high speeds. fiber is used instead of metal because signals travel along them with less loss.

Detailed explanation-3: -Coaxial cable, often referred to as coax (pronounced KO-ax), consists of a single copper wire surrounded by at least three layers: (1) an insulating material, (2) a woven or braided metal, and (3) a plastic outer coating (Figure 8-25).

Detailed explanation-4: -Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference is required. This type of communication can transmit voice, video, and telemetry through local area networks or across long distances.

Detailed explanation-5: -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.
