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

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

4. 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

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

7. 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

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

9. 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
