Guided Media is also known as Wired or Bounded transmission media. A signal travelling the media is directed and confined by the physical limits of the medium. Read: Introduction To Computer Network. Twisted-Pair Cable consists of two insulated conductors wire wound normally copper , twisted together.

UnGuided Transmission

A signal travelling along any of these media is directed and contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic copper conductors that accept and transport signals in the form of electric current. Optical fibre is a cable that accepts and transports signals in the form of light. This cable is the most commonly used and is cheaper than others. It is lightweight, cheap, can be installed easily, and they support many different types of network. Some important points :.

The satellite accepts the signal that is transmitted from the earth station, and it amplifies the signal. The amplified signal is retransmitted to another earth station.

Guided Media

In data communication terminology, a transmission medium is a physical path between the transmitter and the receiver i. Transmission Media is broadly classified into the following types:. Signals being transmitted are directed and confined in a narrow pathway by using physical links. Generally, several such pairs are bundled together in a protective sheath. They are the most widely used Transmission Media.

Bounded or Guided Transmission Media

It is defined as the physical medium through which the signals are transmitted. It is also known as Bounded media. Twisted pair is a physical media made up of a pair of cables twisted with each other. A twisted pair cable is cheap as compared to other transmission media.

This can also be called wireless transmission media. Generally, the waves get guided while transmission but that is not acceptable in this so there are several techniques or procedures to follow for transmitting them. The transmission is done between the destination and source. For making possible transmissions to unguided media, the electromagnetic spectrum is utilized. When coming to propagation through the ground, the transmission is possible even over a distance, and the signals which are propagated from the ground travels through an air vacuum.
