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. Thus we say object component is realized by messages, procedural component is realized by grammar, morphological is realized by material bearers.
