Telecommunication (from Latin communicatio, describing the social process of information exchange, and also the Greek prefix tele-, suggesting range) is the transmission of details by various sorts of modern technologies over cable, radio, optical or various other electro-magnetic systems. It has its beginning in the desire of humans for interaction over a distance greater than that feasible with the human voice, yet with a comparable scale of expediency; hence, slow systems (such as postal mail) are excluded from the field.
The transmission media in telecommunication have evolved via many phases of modern technology, from beacons and also various other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable as well as electromagnetic radiation, consisting of light. Such transmission courses are commonly divided into communication channels, which manage the advantages of multiplexing several simultaneous interaction sessions. Telecommunication is frequently used in its plural form, since it involves many different innovations.
Other examples of pre-modern long-distance communication consisted of audio messages, such as coded rolls, lung-blown horns, as well as loud whistles. 20th- and also 21st-century modern technologies for long-distance interaction typically include electric and electromagnetic modern technologies, such as telegraph, telephone, television as well as teleprinter, networks, radio, microwave transmission, fiber optics, and also communications satellites.
A revolution in wireless communication started in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Reward in Physics in 1909, and various other remarkable pioneering creators as well as developers in the field of electrical as well as electronic telecoms. These consisted of Charles Wheatstone as well as Samuel Morse (creators of the telegraph), Antonio Meucci and Alexander Graham Bell (several of the innovators and also programmers of the telephone, see Development of the telephone), Edwin Armstrong as well as Lee de Forest (creators of radio), along with Vladimir K. Zworykin, John Logie Baird and also Philo Farnsworth (some of the creators of television).
According to Write-up 1.3 of the Radio Regulations (RR), telecommunication is defined as” Any type of transmission, exhaust or function of signs, signals, works, images and sounds or knowledge of any kind of nature by wire, radio, optical or various other electro-magnetic systems.” This meaning is identical to those contained in the Annex to the Constitution as well as Convention of the International Telecommunication Union (Geneva, 1992).
The word telecommunication is a substance of the Greek prefix tele (τηλε), suggesting remote, far off, or afar, and the Latin communicare, indicating to share. Its modern use is adapted from the French, due to the fact that its created usage was recorded in 1904 by the French designer and also author Édouard Estaunié. Interaction was first used as an English word in the late 14th century. It originates from Old French comunicacion (14c., Modern French interaction), from Latin communicationem (nominative communicatio), noun of activity from past participle stem of communicare “to share, separate out; communicate, convey, notify; join, unify, take part in”, literally “to make common”, from communis”.
