This document discusses the elements and understanding of communication, including that communication can only occur to the extent allowed by the social system, the message will be clear if the code is proper, and communication can take place through any of the five senses or their combination. It also notes that for effective communication, the source and receiver need to be at the same level and the source should consider the receiver. The document provides some criticism of previous models of communication for not mentioning feedback, barriers, noise, or additional senses beyond the traditional five.
