 According to the coding model, communication consists in a sender and a receiver sharing a common code or language and a channel, so that the former encodes the message and sends it for the latter to decode it. Communication is, following this picture, quite an easy matter. It just amounts to knowledge of language and a safe channel — i.e., without too much ‘noise.’ If sender and receiver share the knowledge of the code and the message makes its way through the channel the success of communication is guaranteed.
