Solution:

What do you mean by guided transmission media:

Guided means are those that provide a conductor from one device to the other and include twisted-pair cables, coaxial cables, and fiber optic cables.

Guided media which are those that provide a conduit from one device to another, include twisted pair cable, coaxial cable, and, fiber optical cable.

A signal traveling by any of these means is directed and contained by the physical limits of the medium.

Twisted pair and coaxial cable use metallic (copper) conductors that accept and carry electrical current signals.

A fiber optic is a glass or plastic cable that accepts and transports signals in the form of light.

Types of Guided Transmission Media:

There are three types of Guided Transmission Media:

(1) Twisted Pair cable.

(2) Coaxial cable.

(3) Fibre Optic Cable.

(3) Coaxial cable:

Coaxial cable is also known as coax, which is derived from the geometric axis created between a shield and an insulator.

That is shortened to “Coax” cable. A coaxial cable is a copper cable that helps transfer electrical signals between multiple electrical devices, systems, or other components.

It is used in such applications as telephone trunk lines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas.

Instead of having two wires, coax has a central core conductor of solid or stranded wire (usually copper) enclosed in an insulating sheath, which is, in turn, encased in an outer conductor of metal foil, braid, or a combination of the two.

The outer metallic wrapping serves both as a shield against noise and as the second conductor, which completes the circuit.

This outer conductor is also enclosed in an insulating sheath, and the whole cable is protected by a plastic cover.

How do Coaxial Cables work?

The signal a coaxial cable carries is transferred simultaneously through the central wire as well as the separated metal jacketing.

This is done because both conductors generate a magnetic field, as any electrically charged wire does.

However, when two opposite-charged magnetic fields, such as the ones generated by the two conductors, meet one another, and the fields cancel one another out.

This allows the cables to be placed near other sensitive electronic equipment and other metal objects without the danger of the cables acting like magnets.

It also prevents outside magnetic fields from altering the signal the cables carry.
