Telecommunication occurs when the exchange of information between two entities (communication) includes the use of technology.


  • The theory of communication is partly concerned with the measurement of information content of signals, as their essential property in the establishment of communication links. But the information content of signals is not to be regarded as a commodity; it is more a property or potential of the signals, and as a concept it is closely related to the idea of selection, or discrimination. This mathematical theory first arose in telegraphy and telephony, being developed for the purpose of measuring the information content of telecommunication signals. It concerned only the signals themselves as transmitted along wires, or broadcast through the aether, and is quite abstracted from all questions of "meaning." Nor does it concern the importance, the value, or truth to any particular person. As a theory, it lies at the syntactic level of sign theory and is abstracted from the semantic and pragmatic levels. We shall argue … that, though the theory does not directly involve biological elements, it is nevertheless quite basic to the study of human communication — basic but insufficient.

  • In the past, documentation has frequently been compared with librarianship, with some argument as to which comprehends the other. The field is more helpfully characterised if we take its scope to be all forms of document (i.e. any physical carrier of symbolic messages) and all aspects of their handling, from production to delivery. The document system then becomes very much wider than conventional librarianship – it includes publication and printing, distribution, some forms of telecommunication, analysis, storage, retrieval and delivery to the user.
  • Information systems, at any level of complexity above that of speech, necessarily involve technologies such as printing, telecommunications, or computers. However, to information science technical potentialities and constraints are of importance mainly in that they affect the social relations concerned.
