Communication is the exchange of messages through some CHANNEL and in some MEDIUM. Communication theorists usually classify communication into modes, that is, different ways of exchanging messages: for example, gestural (hand-based communication); vocal (voice-based communication); visual (picture-based communication); signaling (bodily based communication); and so on. When pluralized (communications), the term refers to media systems or technologies of communication.
