The classical theory of information and cybernetics used the first - abstracting. It is a quantity of information. The semiotics used the second way. We must offer two definitions for further developing the concept of information. These are a message and a language.
Language is a sign system with alphabet, vocabulary and grammar.
Message is a definite construction in a definite language. Exchange of information is possible by plunge into definite surroundings - own language of this message. Any message is a set of signs without such a plunge. We also point out that information can exist as messages. Information may be extracted from messages.
