Chapter 14, Problem 21RQ
Program Plan Intro
Transmission media:
- Transmission media is also known as communication channel.
- It is defined as a pathway which carries the information from sender to receiver.
- Data is usually transmitted through electrical or electromagnetic signals.
- These signals can be transmitted through copper wires, optical fibers, atmosphere, water, and vacuum.
- Transmission media can be broadly classified into two groups such as wired/guided media and wireless/unguided media.
