What is communication?
Any process that transfers, transmits or makes information known to other people.

Aristotle explained it in his book Rhetoric : -The speaker produces a message that is heard by the listener.

More complex model suggested by Shannon & Weaver: -The speaker produces an effect on the transmitter which sends a message (degraded by the noise of the transmission process) that is intercepted by the receiver which converts it into an effect that is heard by the listener.
Technology is the scientific study of mechanical arts and their application to the world.
Marshall McLuhan argues that technologies are extensions of human body. The tool = extension of hand. The wheel = extension of the leg. The book = an extension of the eye.
