A transmission line, also called a transmission channel, consists of the assembly of the Data Circuit Terminating Equipment (DCTE) of each machine and the data line.
Data Terminal Equipment (DTE) refers to the end machines, while DCTE refers to the equipment for the physical medium to which they are connected.

Data is transmitted on a physical medium by propagation of a vibratory phenomenon, resulting in an undulating signal.
Electromagnetic waves are characterized by their frequency, amplitude, and phase.

Physical transmission media are the elements that allow information to flow between transmission devices.

The purpose of a network is to transmit information from one computer to another, and the data must be encoded for transmission.
Data representation can be divided into two categories: digital representation (encoded as a set of binary values) and analogue representation (represented by the variation in a continuous physical quantity).

A transmission line, also called a transmission channel or channel, is necessary for data transmission to occur between two machines.

An encoding must be chosen for the transmission signals, depending on the physical medium used, guaranteed data integrity, and transmission speed.

Data transmission can be "simple" if there are only two machines communicating, or if only a single piece of data is sent.
Multiplexing is necessary for simultaneous data transmission between multiple actors.

A protocol is a common language used by all actors in the communication to exchange data.
Protocols allow for initiation of communications, data exchange, error detection, and a courteous end of communications.
