Word 'Television' derives itself from the Greece 'tele' and Latin 'vision'. You can consider the word 'television' as a view from afar.
To simplify, television worked by a electronic system, can transform a image to a signal,which is focused on a special chasiss of a camera, and then conveyed by lines to send impluse signals.
The word "television", derived from its Greek (tele: distant) and Latin (visio: sight) roots, can literally be interpreted as sight from a distance. Very simply put, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image(focused on a special photoconductive plate within a camera) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reconstituted into that same image.
