Information Literacy

Information Literacy is the ability to identify what information is needed, understand how the information is organized, identify the best sources of information for a given need, locate those sources, evaluate the sources critically, and share that information. It is the knowledge of commonly used research techniques.

Information literacy is critically important because we are surrounded by a growing ocean of information in all formats. Not all information is created equal: some is authoritative, current, reliable, but some is biased, out of date, misleading, false. The amount of information available is going to keep increasing. The types of technology used to access, manipulate, and create information will likewise expand.

Mind Map!!!!!!!!!!

A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea. Mind maps are used to generate, visualize, structure, and classify ideas, and as an aid to studying and organizing information, solving problems, making decisions, and writing.




The elements of a given mind map are arranged intuitively according to the importance of the concepts, and are classified into groupings, branches, or areas, with the goal of representing semantic or other connections between portions of information. Mind maps may also aid recall of existing memories.

Good Information!!!!!!!!!!!!!!!!!!!

Information good in economics and law is a type commodity whose main market value is derived from the information it contains. It may also include services (information services). The typical examples of information goods include a CD containing pieces of music, a DVD containing a movie, a computer file which is a piece of program, a book containing short stories, and so on.




In information goods, the valuable part is a pattern in which the material is arranged - the arrangement of ink on paper, paint on canvas, magnetic elements on a tape, a series of dents (pits) on a compact disc, etc. Those patterns might be either directly consumed by humans (through reading, viewing, etc.) or may be used to operate other devices such as a cassette player or a computer. The working of device, in turn, may produce some consumable pattern of information (such as visual, sound, or text), another pattern for the use of other devices, or both.

Information Overload

Information overload" is a term popularized by Alvin Toffler that refers to the difficulty a person can have understanding an issue and making decisions that can be caused by the presence of too much information.The term itself is mentioned in a 1964 book by Bertram Gross, The Managing of Organizations




The term and concept precede the Internet. Toffler's explanation of it in his bestselling book presents information overload as the Information Age's version of sensory overload, a term that had been introduced in the 1950s. Sensory overload was thought to cause disorientation and lack of responsiveness. Toffler posited information overload as having the same sorts of effects, but on the higher cognitive functions, writing: "When the individual is plunged into a fast and irregularly changing situation, or a novelty-loaded context ... his predictive accuracy plummets. He can no longer make the reasonably correct assessments on which rational behavior is dependent."
