Information and Information Communication

The inextricably linked concepts of information and information communication are discussed. Information about some entity is defined as details about its properties reflected in material processes and objects or in the response of systems with purposeful activity. It is asserted that information is manifested only in the process of information communication. The steps of this process are considered. In particular, the processes of information transfer studied by C. Shannon are presented as elements of the stage of reflection of information communication. The aspects of information support of typical processes of activity, inherent in a particular subject domain, that must be recognized and studied, are determined. The list of the basic concepts connected with the concept of information is given.
