The document discusses the history of telecommunications including early visual and audio methods and modern electrical methods using devices like the telegraph, telephone, and teletype requiring metal wires. It then provides information on the internet as a global system of interconnected computer networks using standard protocols to serve billions, and discusses satellite communications using orbits to provide mobile applications like communications to ships and planes where cables are impractical.

1. Telecommunications and its history<br />Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals, such as becons, 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 fiber optics and their associated electronics, plus the use of the orbiting satellites and the HYPERLINK quot;

Internet.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 /> Internet Knowledge<br />What is the internet? The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/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 .What services does it provide? A quot;
Smart Clientquot;
application can be <br />created in several very different technologies. The original use of the term in the context of the web was Isomorphic Software's SmartClient product (they own the SmartClient.com domain), which uses an Ajax-based, cross-browser cross-platform approach. Subsequently Microsoft began using the terminology to refer to .NET applications delivered via the Internet Explorer browser to Windows XP<br />Satellite communications<br />A 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, HYPERLINK quot;

Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits.<br />For fixed (point-to-point) services, communications satellites provide a microwave radio relaytechnology 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 />
