In humans, language is considered the major vehicle for the transmission of information.
Information is a very complex phenomenon.
Its transfer involves the coding of a message in a channel that can be perceived and decoded by the receiver. Basically this is a cybernetic model which usually involves various levels of competence in coding, interference in the channel, problems in decoding and a feedback loop to indicate whether the message has been successfully received. This model presumes that the noise in the system can be filtered out so that the transmission is successful. One aspect of the model is that the coding system may be subdivided to discriminate between different senders especially on the basis of individual, age, kin group etc. These levels of differentiation must be distinguishable from coding errors or noise in the system.
