Chapter 1: Data, Information, Knowledge, and Wisdom!

What is information?

Information in its most restricted technical sense is an ordered sequence of symbols that record or transmit a message. It can be recorded as signs, or conveyed as signals by waves. Information is any kind of event that affects the state of a dynamic system. As a concept, however, information has numerous meanings.[1] Moreover, the concept of information is closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, representation, and especially entropy.

What is Data?

 The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e. unprocessed data, refers to a collection of numbers, characters, images or other outputs from devices that collect information to convert physical quantities into symbols.

 What is 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.

What is bad information?
Bad information is a information that can not be use or useless.





Knowledge?
Knowledge is a familiarity with someone or something, that can include facts, descriptions, information, and/or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic.

Wisdom?
Wisdom is a deep understanding and realizing of people, things, events or situations, resulting in the ability to choose or act or inspire to consistently produce the optimum results with a minimum of time, energy or thought. It is the ability to optimally (effectively and efficiently) apply perceptions and knowledge and so produce the desired results. Wisdom is also the comprehension of what is true or right coupled with optimum judgment as to action.

Understanding?

Understanding (also called intellection) is a psychological process related to an abstract or physical object, such as a person, situation, or message whereby one is able to think about it and use concepts to deal adequately with that object. Understanding is a relation between the knower and an object of understanding. Understanding implies abilities and dispositions with respect to an object of knowledge sufficient to support intelligent behavior.

Mind Mapping?

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.
