Guided Media
Guided Media is that contain some conducting material to carry data or signal. Many types of cable and wires fall under this category. Each of them has its own characteristics like transmission speed, effects of noise.Guided media is also known as wired media. In this we will use wires to send our data from one place to other place.
It include: -
Twisted pair
Coaxial Cable
Optical fiber
Unguided Media
It does not contain the signal in some physical conductor or metal. Rather, it transport electromagnetic signal through air. It is also known as wireless media. Because in this we are not using any king of cable.
It includes: -
Radio waves
Micro waves
Infrared waves
Radio waves Transmission
The Radio waves have frequencies between 3khz and1Ghz
Radio waves are Omni direction
Radio waves can penetrate buildings easily, so that are widely use for communication both indoors outdoors.
They also absorbed by rains
At high frequency, radio wave tends to travel in straight line and bounces off the obstacles.
