Telecommunication (from two words, tele meaning 'from far distances' and communication meaning to share information) is the assisted transmission of signals over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags, or a mirror to flash sunlight. Starting with the telegraph, telecommunication typically involves the use of electronic transmitters such as the telephone, television, radio, optical fiber and computer.
