答案

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.
