Information is the identity of a thing; the property that specifies the characteristics of something, such as the physical properties that compose a physical system. The word is used for a variety of different reasons and originally, it had come from a word meant for giving a form to something. Knowledge-related information is something that both humans and animals can learn, know about, or understand. For example, a newspaper is something that contains knowledge about a chosen aspect of the world. This article contains information about the concept of "information".
Information in computer science[change | change source]
In the 1970s and 1980s, some people gave a new, specific meaning to "information". At that time, the first computer databases were built. In computer science, data often means a kind of information that has not been checked. That means data has not been changed or fixed, and you may not be able to trust it. With the new meaning, information means data that has been checked and passed tests for what it must be. A person can trust that "information" is correct.
Information can only be correct and good enough to trust if there are very good and complete ways to check the data (data checking, validation or verification) and decide it is good enough (acceptance process). A person must know rules were used to check the data or trust the person who checked the data. If a person cannot tell that this was done, the information still seems to be data for that person, so that person must check the data again, in that general view about data.
