Communication theory is thoroughly statistical and it forms the basis for a description of any cybernetic system. The book introduces the theory of information as a necessary means of looking at facts from the point of view of cybernetics.
Cybernetic systems deal primarily with communication and control.
Cybernetics is the mathematics of information processing and its technical realization. By communication we understand the type of scheme in which information is transmitted from one point to another. Information is neither matter nor energy. It is a casting mould, a scheme, a construction rule, a structure, an instruction for use depending on which aspect of the situation we want to look at. We cannot and should not always speak in precise and well-defined terms.
