What is Transmission Media? : Guided and Unguided Transmission Media

Transmission Media

Transmission media is a medium that carries a signal from one computer to another. It is also known as a communication channel. transmission media can be of two types:

1.  Guided Transmission Media (Wired Transmission Media)
2.  Unguided Transmission Media (Wireless Transmission Media)

Guided Transmission Media

This media physically connects the two or more computers. The data signal physically gets transferred from the source computer to the destination computer through the wired transmission medium.

Some of the Guided media are as follows: 

• Twisted pair cable
• Coaxial cable
• Optical Fiber

Unguided Transmission Media

Unguided or wireless transmission media transfer electromagnetic waves without using a physical conductor the signal is broadcasted through air or water.

Some of the Unguided media are as follows: 

• Infrared
• Radio Wave
• Microwave
• Satellite Link
