Telecommunication in the modern era is the science and practice of transmitting information by
electromagnetic means.
In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke
signals, semaphore telegraphs, signal flags, and optical heliographs, or audio messages such as
coded drumbeats, lung-blown horns, and loud whistles.
In modern times, telecommunications
involves the use of electrical devices such as the telegraph, telephone, and teleprinter, as well as
the use of radio, microwave transmission towers, fiber optics, orbiting satellites and the Internet,
which is a vast world-wide computer network.
A revolution in wireless telecommunications began in the first decade of the 1900s with
pioneering developments in radio communications by Nikola Tesla and Guglielmo Marconi.
Marconi won the Nobel Prize in Physics in 1909 for his efforts.
