Transmission media
-> Transmission media is a communication channel that carries the information from the sender to the receiver. Data is transmitted through the electromagnetic signals.
-> The main functionality of the transmission media is to carry the information in the form of bits through LAN(Local Area Network).
-> It is a physical path between transmitter and receiver in data communication.
-> In a copper-based network, the bits in the form of electrical signals.
-> In a fibre based network, the bits in the form of light pulses.
-> The transmission media is available in the lowest layer of the OSI reference model, i.e., Physical layer.
Factors to be considered while selecting a Transmission Medium
1. Transmission Rate
2. Cost and Ease of Installation
3. Resistance to Environmental Conditions
4. Distances
Classification Of Transmission Media
1. Guided Transmission media
2. Unguided Transmission media
