The elements of a telecommunication system are a transmitter?, a channel?, a line? and a receiver?. The transmitter is a device that transforms or codes the message into a physical phenomenon called the signal. The transmission channel, by its physical nature, is likely to modify or degrade the signal on its path from the transmitter to the reciever. The reciever has a decoding mechanism capable of recovering the message within certain limits of signal degradation by the communication channel.

Telecommunication can be point-to-point or point-to-multipoint in which case it is called conferencing. Broadcasting is a particular form of telecommunication that is point-to-multipoint and goes predominantly from the transmitter to the recievers.
