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.<br />satellite<br />GPS<br />Tower of commuication <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.<br />
What service does it provide?

What is a bandwidth?
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies.

While there are natural satellites, like the Moon, hundreds of man-made satellites also orbit the Earth.<br />What services does a satellite provide?<br />Internet like Google Skype Google earth etc.<br />What is an orbit?<br />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.<br />What is a communication satellite?<br />A communications satellite is an artificial satellite stationed in space for the purpose of telecommunications.<br />Examples of communication satellites?<br />
