Telecommunication is the transmission of signals, sounds and messages or information by Electrical means or by Electromagnetic means such as wires, radios, optical, fibres and other electromagnetic systems. Telecommunication is achieved when the exchange or transmission of information between the sender and the receiver is successful. Transmission can be either Electrically over physical media, such as cables, or via Electromagnetic radiation.
In the Early days, means of communicating occurs over a distance using visual signals, such as smoke signals, beacons, signal flags, semaphore telegraphs and optical heliographs. Wireless communication revolution began in the first decade of the 20th century with the developments in radio communications pioneered by Guglielmo Marconi.
In 1909 he won the Nobel Prize in Physics, and other notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Alexander Graham Bell (inventor of the telephone), Charles Wheatstone and Samuel Morse (inventors of the telegraph), Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth (some of the inventors of television), Edwin Armstrong and Lee de Forest (inventors of radio)
