telecommunication and its history telecommunication and its history Document Transcript

  • Telecommunication in our sociatyJoese Antonio Monroy1/1/2011Interamerican school7th gradesignificant 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 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 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 />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.what is web 2.0? The term Web 2.0 is associated with web applications that facilitate participatory information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web. A Web 2.0 site allows users to interact and collaborate with each other in a social media dialogue as creators (prosumers) of user-generated content in a virtual community, in contrast to websites where users (consumers) are limited to the passive viewing of content that was created for them.what sevices does it provide? Many people use the terms Internet and World Wide Web, or just the Web, interchangeably, but the two terms are not synonymous.bandwindh: frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz.<br />what is a satellite? A satellite is an object that goes around, or orbits, a larger object, such as a planet. While there are natural satellites, like the Moon, hundreds of man-made satellites also orbit the Earth.what services or uses does a satellite provide? Satellite Internet access is Internet access provided through satellites. The service can be provided to users world-wide through Low Earth Orbit satellites. Geostationary satellites can offer higher data speeds, but their signals can not reach some polar regions of the world.can you give a examples of comunication satellite? Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits.what elements form a satellite comunication system? * Communication Payload, normally composed of satellite transponder, antenna and switching sytems<br /> * Engines used to bring the staellite to its desired orbit<br /> * Station Kreeping Tracking and stabilization subsytem used to keep the staellite in the right orbit , with its antennas pointed in the right direction, and its power system ponted towards the sun<br /> * Power subsystem, used to power the Satellite systems, normally composed of Solar Cell, and batteries that mauntain power during Solar Eclipse<br /> * Command and Control subsytem, which maintains communications with ground conrol stations, The ground conrols earth stations monitor the staellite performance and control its funconality during various phases of its life-cycle.<br />what is 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. what is the importance of meteorology? Meteorology is important because we are leanring about our atmosphere, the weather, and the things that shape our world. how are telecommunication and satellites useful for meteorology? 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. The nineteenth century saw breakthroughs occur after observing networks developed across several countries. Breakthroughs in weather forecasting were achieved in the latter half of the twentieth century, after the development of the computer.<br />Meteorological phenomena are observable weather events which illuminate and are explained by the science of meteorology.<br />
