The definition of information is presented in various ways in the consulted literature. Information can be defined as a fact, an event, a statement. However, if a fact is not communicated, it will not be information, as well as a statement, without the In fact, it will not be consistent. Thus, a more refined definition for information would be: a communicated fact. Information is a process of transmission and transfer of knowledge: forms, data, and concepts, studies with the aim of making it accessible to another person, institution or society. The quality of this process will determine whether or not the individual's behaviour and attitude change receives the information. It is worth remembering that information is not synonymous with knowledge. The term information has the following attributes: - Considered almost as a synonym for the term fact; - A reinforcement of what is already known; - Freedom of choice when selecting a message; - The raw material from which knowledge is extracted; - What is exchanged with the outside world and not just received passively; - Defined in terms of its effects on the recipient; - Something that reduces uncertainty in a given situation. Information and knowledge are correlated but are not synonymous. It is also necessary to distinguish two types of knowledge: - Raw knowledge - which, transformed into information, can be reproduced, plastered, transferred, acquired, traded, etc. - and - Tacit knowledge. For them, the transformation into signs or codes is extremely difficult since their nature is associated with learning processes, totally dependent on specific contexts and forms of social interaction. There are three different types of knowledge: - Explicit knowledge: it is the set of information that is already based on some support (books, documents, etc.) and that characterizes the knowledge available on a specific topic; - Tacit knowledge: it is the accumulation of practical knowledge on a given subject, which adds convictions, beliefs, feelings, emotions and other factors linked to the experience and personality of those who have this knowledge; - Strategic knowledge: it is the combination of explicit and tacit knowledge formed from the accompanying information, adding the knowledge of specialists.
