Q. What are three categories of wired media? Explain them.

Answer: -

(i) Twisted-Pair Cables: - These cables consist of two insulated copper wires twisted around each other. These are also used for short and medium range telephone communication.

(ii) Coaxial Cables: - A coaxial cable consists of one or more small cables in protective covering. These are more expensive than twisted pair cables but perform better.

(iii) Fiber-optic Cables: - These cables are made of plastic or glass and are about as thick as human hair. These cables are highly durable and offer excellent performance but are expensive.
