Abstract

The historical evolution both notions “information” and “energy” are analogous. This is evolution from “attribute of life only” to universal notions. Knowing of energy as universal phenomenon brought to people the great technological breakthrough. But evolution of the first notion is not complete. There is not standardconception of information. While this phenomenon is not determined, it is impossible to do the unequivocal conclusions on the many questions, connected to it. The detailed analysis shows that information appears as a result of comparison. New definition of information ensues hereof. Information is correlations of properties that are determined by comparison or interaction of objects and exists in matter carrier. The author analyses trustiness and universality of this definition. On base the definitions information and structure he proves their equivalence that is illustrated by samples also. As result the author concludes that “information” is so fundamental notion, either as “structure”, and formulates some important consequences. Information exists in any object, it is transformed by any interaction and it plays the most important role even in evolution of lifeless nature.
