Television is a compound world. It comes from the Latin word 'tele' and 'vision'. 'Tele' means distance and 'vision' means to see. So the world television means seeing from distance. Television is an instrument which sends pictures to distant places.It is one of the wonders of modern science.
Papul Nepkow, a German scientist at first thought of sending image to a distant place. Later, on the basis of this experiment television was invented. A British scientist, John Bayard at first invented television in 1925.
Television is powerful mass-media. It enables us to see and hearing something which is happening hundreds of miles away. It has a significant role in the following sectors.
The broadcast telecom system is usually disseminated via radio transmissions on selected channels within the 54–890 megacycle waveband.Signals area unit currently typically transmitted with stereo or surround sound in several countries. till the 2000s, broadcast TV programs were typically transmitted as AN analog tv signal however throughout the last decade many countries went nearly completely digital.
A standard television contains multiple internal electronic circuits, as well as those for receiving and decryption broadcast signals. a visible show device that lacks a tuner is correctly known as a video monitor, instead of a tv. A telecom system might use totally different technical standards like digital tv (DTV) and telecasting (HDTV) .
TV stems also are used for police work, process management, and guiding of weapons, in places wherever direct observation is troublesome or dangerous. Some studies have found a link between infancy exposure to TV and minimal brain dysfunction.
