Communication

Communication (from Latin commūnicāre, meaning "to share") is the purposeful activity of information exchange between two or more participants in order to convey or receive the intended meanings through a shared system of signs and semiotic rules. The basic steps of communication are forming communicative intent, message composition, message encoding, the transmission of the signal, reception of the movement/signal, message decoding and finally interpretation of the message by the recipient.

Communication in general takes place inside and between three main subject categories: human beings, living organisms in general and communication-enabled devices (for example sensor networks and control systems). Communication in the category of living organisms (studied in the field of biosemiotics) usually occurs through visual, auditory, or biochemical means. Human communication/touch is unique for its extensive use of language.
