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 via coded drumbeats, lung-blown horns, or sent by loud whistles, for example. In the modern age of electricity and electronics, telecommunications now also includes the use of electrical devices such as telegraphs, telephones, and teletypes, the use of radio and microwave communications, as well as optics and their associated electronics, plus the use of the satellites and the internet.<br />The first breakthrough into modern electrical telecommunications came with the push to fully develop the telegraph starting in the 1830s. The use of these electrical means of communications exploded into use on all of the continents of the world during the 19th century, and these also connected the continents via cables on the floors of the ocean. The use of the first three popular systems of electrical telecommunications, the telegraph, telephone and teletype, all required the use of conducting metal wires.<br />Satellite!<br />Tower of communication!<br />The communication in the entire world.<br />Internet knowledge<br />What is the history of internet?<br /><ul><li>Although the history of the Internet arguably begins in the 19th century with the invention of the telegraph system, the modern history of the Internet starts in the 1950s and 1960s with the development of computers.</li></ul>Why is important of internet and communication?<br /><ul><li>Telecommunication is the transmission of information, over significant distances, to communicate.

Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.</li></ul>What is an orbit?<br /><ul><li>An orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the solar system.
Meteorology is the interdisciplinary scientific study of the atmosphere. Studies in the field stretch back millennia, though significant progress in meteorology did not occur until the eighteenth century.
