Detailed explanation-1: -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).
Detailed explanation-2: -Technical devices can therefore be employed to transmit or guide waves. Thus, an optical fiber or a copper cable is used as transmission media.
Detailed explanation-3: -A transmission media in data communication is a physical path between the sender and the receiver and it is the channel through which data can be sent from one location to another. Data can be represented through signals by computers and other sorts of telecommunication devices.
Detailed explanation-4: -The optical fibre is a communication medium where the data is transformed into pulses of light emitted by a laser device about the six of a pinhead and can be transmitted at blinding speeds.
