Communication is a process that allows organisms to exchange information by several methods. Exchange requires feedback. The word communication is also used in the context where little or no feedback is expected such as broadcasting, or where the feedback may be delayed as the sender or receiver use different methods, technologies, timing and means for feedback.

Communication is the articulation of sending a message, whether it be verbal or nonverbal, so long as a being transmits a thought provoking idea, gesture, action, etc. . .

Communication can be defined as the process of meaningful interaction among human beings. It is the act of passing information and the process by which meanings are exchanged so as to produce understanding.
