Types of communication Media used in computer Networks
The path along which data is transmitted from one place to
another is called as communication
medium or communication channel.
Following are the types of communication media:
Guided Media:
In this method,the communication devices are directly
connected to one another by some form of physical media such as wires.
It is also called as bounded media.
Some examples of this type of medium include:
Twisted pair
Co-axial cable
Fiber optics
Unguided Media:
In this type of medium,communication devices communicate with
each other using air or space via broadcast signals.
Some examples of these broad cast signals include:
Radio signals
Microwave signals
Infrared signals.
This type of medium is used in places where it is not
possible to install cables.
Some examples of unbounded media are as follows:
Microwave
Communication satellite
Mobile communications.
