Source of Communications....

Communication can be seen as processes of information transmission governed by three levels of semiotic rules:
Syntactic (formal properties of signs and symbols),
pragmatic (concerned with the relations between signs/expressions and their users) and
semantic (study of relationships between signs and symbols and what they represent).
Therefore, communication is a kind of social interaction where at least two interacting agents share a common set of signs and a common set of semiotic rules. (This commonly held rule in some sense ignores autocommunication, including intrapersonal communication via diaries or self-talk).
In a simple model, information or content (e.g. a message in natural language) is sent in some form (as spoken language) from an emisor/sender/encoder to a destination/receiver/decoder. In a slightly more complex form a sender and a receiver are linked reciprocally
