Given instructions, the learner will discuss different components of telecommunications with 85% accuracy.

Telecommunication is the transmission of information over significant distances, for the purpose of communication.

Early communication involved the use of visual signals and audio messages such as: Beacons Smoke Semaphore telegraphs Signal Flags Optical heliographs Drumbeats Lung-blown horns Loud whistles

Modern Age devices used electricity and electronics such as: Telegraph Telephones Teletypes Radio Microwave communication Fiber Optics Orbiting Satellites and Internet

A sending device is a generally computer. A communication device, such as a modem, that converts the computer signal into signals supported by the communication channel. A Communications Channel or path, such as telephone lines, cable, or a wireless transmission link, over which the signal are sent. A receiving device that accepts the incoming signal, which is a general computer. Communication software

Radio signals travel in a straight line from one source to the other.

A microwave signal is sent through space in the form of electromagnetic waves. The signal is also sent is a straight line. Doppler Radar Microwave Station Microwave Station

Communication satellites are placed in orbit 22,300 ft above the surface of the Earth. &cp= ~-99.71&style=h&lvl=4&tilt= &dir=0&alt= &cp= ~-99.71&style=h&lvl=4&tilt= &dir=0&alt=
