  1. 1. Interamerican School7° Grade31/05/11Telecommunicatios and its history.Made by: Karla Figueroa♥ princesa_aleana@hotmail.com<br />t<br />2990852552700Elecommunication is the transmission of information, over significant distances, to communicate. 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 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 fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet. <br />27457401733551139114102136<br />-85725594360<br />The Internet is a global system of interconnected computer networks that use the standard Internet Protocol SuiteTCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. An umbrella term for the second wave of the World Wide Web, which was coined in a conference on the subject in 2004 by O'Reilly Media and CMP Media (later taking its parent name of United Business Media). Sometimes called the "New Internet" as well as "Internet 2.0," Web 2.0 is not a specific technology; rather, it refers to two major paradigm shifts. The one most often touted is "user-generated content," which relates more to individuals. The second, which is equally significant, but more related to business, is "cloud computing."<br />2733675562610Satelite Communications<br />2933700241300A communications satellite (sometimes abbreviated to COMSAT) is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits. <br />34766252872105257175978535For fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting, for which application of other technologies, such as cable, is impractical or impossible.<br />
