Shannon's diagram of a general communication system.<br />
Here are laid out the basic elements of communication as they were<br />
<strong>de</strong>veloped by Shannon and others:<br />
1. Source, emissor, sen<strong>de</strong>r (by whom the information is conveyed?).<br />
When we speak, write, smile, and make gesture we are in the posture of<br />
sen<strong>de</strong>r. Information source produces a message or sequence of messages to be<br />
communicated to the receiving terminal.<br />
2. Message (what types of things and in what form are<br />
communicated?). Message is information which is sent from a source to a<br />
receiver. It may be any thought expressed in a language, prepared in a form<br />
suitable for transmission by any means of communication. In communication<br />
between humans, messages can be verbal or nonverbal:<br />
A verbal message is an exchange of information using words.<br />
Examples inclu<strong>de</strong> face-to-face communication, telephone calls, voicemails,<br />
etc. A nonverbal message is communicated through actions or behaviors<br />
rather than words. Examples inclu<strong>de</strong> the use of body language.<br />
3. Encoding is a process of message production. To codify means to<br />
translate our i<strong>de</strong>as, attitu<strong>de</strong>s, emotions into language. Language may be<br />
spoken and written (i.e. sounds and words). Also there are paralanguage (for<br />
instance tone of voice, quality of voice, rhythm and intonation), and body<br />
language (for instance posture and gesture).<br />
4. Transmitter operates on the message in some way to produce<br />
a signal suitable for transmission over the channel. In telephony this<br />
operation consists merely of changing sound pressure into a proportional<br />
