Elements of communication:
· Issuer: transmitting the information element. It can be a person, body corporate, a media or any other reality.
Receiver unit: component that receives and interprets information. Can be individual or collective.
· Message: Information that is transmitted. Message characteristics depend largely on the kind of code that is used. Understanding the message by the receiver requires consideration also of self-knowledge, the situation in which it occurs and the communicative intention of the issuer.
· Canal: natural or man-made vehicle for transmitting the message. It may be a natural physical environment or an artificial environment.
· Code: A set of signs and rules of combination that enables the development of the message. To produce a record of communication, the sender and receiver must share the same code.
The issuer is responsible for the coding operation is to organize the signs of a code containing the information transmitted. Receptor belongs to the inverse: the decoding.
· Context: situation surrounding the act of communication and influencing their interpretation. In any communicative situation are both linguistic and extralinguistic circumstances: relationship between sender and receiver, where communication occurs. Currently, Pragmatics is the discipline of linguistics that studies language in relation to their use, is concerned, therefore, the extra-linguistic situation that allows the correct interpretation of the message in a communication process.
Depending on the context, messages can no longer make sense or have different meanings.
