Communication involve the transmission of information from one point to other point (destination) through a series of process. Radio communication is made possible by the invention of the triode tube. It subsequently became even more widely used and refined through the invention and use of the transistor, integrated circuits and other semiconductor devices.
The use of satellites and fiber optics has made communications even more widespread, with an increasing emphasis on computer and other data communications.
Modern communications system is first concerned with the storing, processing and storing of information before its transmission. The actual transmission then follows with further processing and the filtering of noise. Reception include processing steps such as decoding, storage and interpretation.
Forms of communications include radio communication, broadcasting, point-to-point and mobile communications, data communications, etc.
