Transmission media is the physical path that carry data from transmitter to receiver. The signals Transmitted from one device to another device in the form of electromagnetic energy with the help of transmission media. The Transmission media can be divided into two classes:: Guided Media and Unguided Media.
Gutded transmission media uses a cabling system that guides the data signals along a specific path. The data signals are bounded by the cabling system. Guided media is also known as bound media. “Cabling “ is meant in a generic sense, and is not meant to be interpreted as copper wire cabling only. The followings are the basic guided media used in networking :;
1. Coaxial cable
2. Twisted-pair cable
3. Fiber optic cable
