Understanding Information


Information is a message (utterance or expression) or collection of messages that consists of order sequences of symbols, or meanings that can be interpreted from a message or set of messages. Information can be recorded or transmitted. It can be recorded as signs, or as signals by waves. Information is the kind of event that affects the state of a dynamic system. The concept has many different meanings in different contexts. [1] Information can say the knowledge gained from learning, experience, or instruction [2]. However, the term has multiple meanings depending on the context, and in general closely related concepts such as meaning, knowledge, negentropy, Perception, Stimulus, communication, truth, representation, and mental stimulation.

In some cases the knowledge of certain events or situations that has been gathered or received via the communication, intelligence gathering, or obtained from the news also called information. The information in the form of a collection of data and facts are often called statistical information. In the field of computer science, information is data that is stored, processed, or transmitted. This study focuses on the definition of information as knowledge gained from learning, experience, or instruction and flow.

Information is data that has been given meaning through context. For example, the form of a spreadsheet document (eg Microsoft Excel) are often used to create information from data contained in it. The income statement and balance sheet is a form of information, while the figures in it is the data that has been given the context that it becomes meaningless and benefits.

a. Understanding the Information Etymology

Said the information comes from the old French word informacion (in 1387) taken from the Latin word meaning informationem "outlines, concepts, ideas." Information is from the noun meaning informare activity in the "knowledge communicated" [3].

Information is a vital function to help reduce a person's anxiety. According Notoatmodjo (2008) that more information can affect or increase one's knowledge and raise awareness with the knowledge that eventually someone will behave in accordance with that knowledge.

The Greek kunokata to formadalah μορφή (morphe; cf. Morph) and also εἶδος (eidos) "idea, shape, set", the last word is commonly used in the technical philosophical sense by Plato (and later Aristotle) ​​to denote the ideal identity or essence of something (see Theory of forms). "Eidos" can also be associated with thought, proposition or even concept.

b. The term information

Many people use the term "information age", "information society," and information technology, in the field of information science and computer science are often highlighted, but the word "information" is often used without careful consideration of the various meanings it has.

c. As sensory input

Often information is viewed as a type of input to an organism or system. Some important input to the function of the organism (eg, food) or system (energy) by themselves. In bukunyaSensory Ecology, Dusenbery said that causal input. Other inputs (information) are important only because they are associated with causal inputs and can be used to predict the occurrence of a causal input at a later time (or possibly elsewhere). Some information is important because of the association with other information must have a connection to a causal input. In practice, information is usually carried by weak stimuli that must be detected by specialized sensory systems and amplified by energy inputs before they are able to function in an organism or system. For example, light is often a causal input to plants but provides information to animals. Reflected light colored flowers too weak to do much photosynthetic work but the visual system of the bee detects and bee nervous system uses the information to guide the bee to the flower, where the bee to find the nectar or pollen, which are causal inputs, serving a nutritional function.

d. As representation and complexity

Cognitive science and applied mathematics Ronaldo Vigo found that information is a relative concept that involves at least two related entities in order to make sense. These are: any category defined-dimensional objects S, and any action R. R, in essence, is a representation of S, or, in other words, carry or convey representational (and hence, conceptual) information about S. Vigo then defines the amount of information conveyed R on S as the rate of change in the complexity of S whenever the objects in R removed from S. Under "Vigo information", pattern, invariance, complexity, representation, and five-universal basic information science that are united under a new mathematical framework. [4] In other words, the framework aims to overcome the limitations of Shannon-Weaver information when attempting to characterize and measure subjective information.
