Guided media. Two hands coming out off computer monitors and shaking each other. Source: Microsoft. The most common type of cable used in data communications is copper. There are different types of copper cable but they all share the feature of transmitting data as an electrical signal. This gives rise to one of the
Discuss the advantages and disadvantages of the guided media types. o Twisted-pair wire: Widely available but speed and distance limitations. o Coaxial Cable: clearer and faster than twisted-pair wire but more expensive.

What are guided unguided media? In a guided medium signal passes through a physical pathway(s),while in an unguided medium signal passes through a vacuum,it is independent of a physical pathway. Edit. Share to:
Answer to What are the guided and unguided transmission media and what are the differences? Discuss advantages and disadvantages o
guided media is a communication medium which allows the data to get guided along it .For this the media need to have a point to point physical connection.
Guided transmission media are more commonly known as the wired communication or bounded transmission media. The electromagnetic signals travel between the communicating devices through a physical medium/conductor. As the medium for transmission is a physical conductor, it also provides direction to the signal. But there are physical limitations of the conductor in the guided media. Like the length of the conductor, its installation cost, its maintenance, etc.
The twisted pair cable has two conductors wires wounded around each other and each surrounded by an insulating material.
he coaxial cable has a central core conductor (usually copper) enclosed in an insulating sheath, which is further encased in an outer metallic braid, it serves as both protection against noise and as a second conductor which completes the circuit.
The optical fibre which is made of glass or plastic, and it transmits signals in the form of light. The optical fibre is noise resistance, has less signal attenuation and has a higher bandwidth in comparison to twisted pair cable and coaxial cable.
Advantages:
1.Higher bandwidth
2.Immunity to electromagnetic interference
3.Resistance to corrosive materials
4.Lightweight
5.Less signal attenuation.
Disadvantages:
1.More difficult installation
2.Very costly
3.Bending is not easy
4.Limited in distance
