Telecommunication is the assisted transmission of signals over a distance for the purpose of communication.
The word “telecommunication” was adapted from the French word “telecommunication”. It is a compound of the Greek prefix tele-, meaning “far off”, and the Latin “communicare”, meaning “to share”. The French word “telecommunication” was coined in 1904 by French engineer and novelist Edouard Estaunie.
In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags, or heliograph. In modern times, telecommunication typically involves the use of electronic transmitters such as the telephone, television, radio or computer. Early inventors in the field of telecommunication include Antonio Meucci, Alexander Graham Bell, Guglielmo Marconi and John Logie Baird. Telecommunication is an important part of the world economy and the telecommunication industry’s revenue has been placed at just under 3 percent of the gross world product.

A telecommunication system consists of three basic elements:
– a transmitter that takes information and converts it to a signal;
– a transmission medium that carries the signal; and,
– a receiver that receives the signal and converts it back into usable information.
For example, in a radio broadcast the broadcast tower is the transmitter, free space is the transmission medium and the radio is the receiver. Often telecommunication systems are two-way with a single device acting as both a transmitter and receiver or transceiver. For example, a mobile phone is a transceiver.
Telecommunication over a phone line is called point-to-point communication because it is between one transmitter and one receiver. Telecommunication through radio broadcasts is called broadcast communication because it is between one powerful transmitter and numerous receivers.

Signals can be either analogue or digital. In an analogue signal, the signal is varied continuously with respect to the information. In a digital signal, the information is encoded as a set of discrete values (for example ones and zeros). During transmission the information contained in analogue signals will be degraded by noise. Conversely, unless the noise exceeds a certain threshold, the information contained in digital signals will remain intact. This noise resistance represents a key advantage of digital signals over analogue signals.
