The goal of communication is to convey information—and the understanding of that information—from one person or group to another person or group. This communication process is divided into three basic components: A sender transmits a message through a channel to the receiver. (Figure shows a more elaborate model.) The sender first develops an idea, which is composed into a message and then transmitted to the other party, who interprets the message and receives meaning. Information theorists have added somewhat more complicated language. Developing a message is known as encoding. Interpreting the message is referred to as decoding.
