Transmission media

A communication channel that transmits data from a source to a recipient is referred to as "transmission media." Electromagnetic impulses are used to transmit data. Transmission media's primary purpose is to transmit data in the form of bits via a local area network (LAN). In data transport, it is the physical link that connects the transmitter and receiver. Transmission medium is part of layer 1 or physical layer of the ISO/OSI (Open System Interconnection) model.
