Telecommunication is that the exchange of signs, signals, messages, words, writings, pictures and sounds or info of any nature by wire, radio, optical or alternative magnetic force systems.Telecommunication happens once the exchange of knowledge between communication participants includes the utilization of technology. it's transmitted through a transmission medium, like over physical media, for instance, over cable, or via radiation through house like radio or light-weight. Such transmission methods area unit usually divided into communication channels that afford the benefits of multiplexing. Since the Latin term communicatio is taken into account the human process of knowledge exchange, the term telecommunications is commonly employed in its form as a result of it involves many alternative technologies.[9] Early suggests that of human action over a distance enclosed visual signals, like beacons, smoke signals, semaphore telegraphs, signal flags and optical heliographs.[10] alternative samples of pre-modern long-distance communication enclosed audio messages like coded drumbeats, lung-blown horns, and loud whistles. 20th- and 21st-century technologies for long-distance communication sometimes involve electrical and magnetic force technologies, like telegraph, telephone, tv and telex, networks, radio, microwave transmission, fibre, and communications satellites A revolution in wireless communication began within the initial decade of the twentieth century with the pioneering developments in radio communications by Guglielmo Marconi, World Health Organization won the honour in Physics in 1909, and alternative notable pioneering inventors and developers within the field of electrical and electronic telecommunications
