Information is the result of processing, manipulating and organizing data in a way that adds to the knowledge of the receiver. In other words, it is the context in which data is taken.
Information as a concept bears a diversity of meanings, from everyday usage to technical settings. Generally speaking, the concept of information is closely related to notions of constraint , communication , control , data , form , instruction , knowledge , meaning , mental stimulus , pattern , perception , and representation . (Wikipedia,2007)

One of the most common ways to define information is to describe it as one or more statements or facts that are received by a human and that have some form of worth to the recipient.[Information is the meaning of the representation of a fact (or of a message) for the receiver.]

Information must:
1. be something, although the exact nature (substance, energy, or abstract concept) isn't clear;
2. provide "new" information: a repetition of previously received messages isn't informative;
3. be "true:" a lie or false or counterfactual information is mis-information , not information itself;
4. be "about" something.
(Bob Losee, 1999)

Information theory is a discipline in applied mathematics involving the quantification of data with the goal of enabling as much data as possible to be reliably stored on a medium or communicated over a channel. The measure of information, known as information entropy , is usually expressed by the average number of bits needed for storage or communication. For example, if a daily weather description has an entropy of 3 bits, then, over enough days, we can describe daily weather with an average of approximately 3 bits per day. (Wikipedia,2007)

Information theory is concerned with the analysis of an entity called a "communication system", which has traditionally been represented by the block diagram shown in Fig. 1.1.1.

An information society is a society in which the creation, distribution, diffusion, use, and manipulation of information is a significant economic, political, and cultural activity. The knowledge economy is its economic counterpart whereby wealth is created through the economic exploitation of understanding. (Wikipedia,2007)

A society in which economic and cultural life is critically dependent on information and communications technologies. Popularised in Europe by the 1994 Bangemann report on 'Europe and the global information society'. Similar to the NII and GII concepts but focusing less on technology, more on uses.

A society in which information becomes the main product or essential to other products, with a recognition that organizations success depends on the ability to exploit information, and most workers depend on information flow to perform their jobs. In practice, information is heavily dependent on computerised processes and the internet.

a type of society in which information and information access plays a central role, economically, socially and individually. Governments are making efforts to bring countries into this era.

The terms news trade or news business refers to news-related organizations in the mass media (or "information media") as a business entity —associated with but distinct from the profession of journalism. (Wikipedia,2007)

The news media refers to the section of the mass media that focuses on presenting current news to the public. These include print media ( newspapers , magazines ); broadcast media ( radio stations , television stations , television networks ), and increasingly Internet -based media ( World Wide Web pages, weblogs ).
