From the stance of information theory, information is taken as a sequence of symbols from an alphabet, say an input alphabet χ, and an output alphabet ϒ. Information processing consists of an input-output function that maps any input sequence from χ into an output sequence from ϒ. The mapping may be probabilistic or determinate. It may have memory or be memoryless.<ref name="Wicker">{{cite book |title=Fundamentals of Codes, Graphs, and Iterative Decoding |author=Wicker, Stephen B.; Kim, Saejoon |publisher=Springer |year=2003 |url=http://books.google.com/books?id=rMu-R3FFG54C&pg=PA1 |pages=1 |isbn=1402072643}}<br />

Information cannot be predicted and resolves uncertainty. The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that. The more uncertain an event, the more information is required to resolve uncertainty of that event. The amount of information is measured in bits.<ref name="Floridi">{{cite book |url=http://books.google.com/books?id=VupFqa3IJiUC |author=Floridi, Luciano |title=Information - A Very Short Introduction |publisher=Oxford University Press |pages=130 |year=2010 |isbn=0199551375}}</ref> The concept that ''information is the message'' has different meanings in different contexts. Thus the concept of information becomes closely related to notions of constraint, communication, control, data, form, instruction, knowledge, meaning, understanding, stimulation, pattern, perception, representation, and entropy.<ref name="Floridi" /><br />
<br />
==Variations of information==<br />
<br />
===As sensory input===<br />
Often information can be viewed as a type of input to an organism or system. Some inputs are important to the function of the organism (for example, food) or to the system itself (energy) and are called causal inputs. 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 (and perhaps another place). Some information is important because of its association with other information, but eventually there must be a connection to a causal input.<ref name="Dusenberry">{{cite book |title=Sensory Ecology: How Organisms Acquire and Respond to Information |author=Dusenbery, David B. |publisher=W H Freeman Limited |year=1992 |url=http://books.google.com/books?id=6S1mQgAACAAJ |pages=558 |isbn=0716723336}}</ref> <br />
<br />
In practice, information is usually carried by weak stimuli that must be detected by specialized sensory systems and amplified by energy inputs before they can be functional to the organism or system. For example, light is often a causal input to plants but provides information to animals. The colored light reflected from a flower is too weak to do much photosynthetic work. However, the visual system of the bee detects it, and the bee's nervous system uses the information to guide the bee to the flower, where the bee often finds nectar or pollen, causal inputs serving a nutritional function.<ref name="Dusenberry" /><br />
<br />
===As representation and complexity===<br />
One theory says information is a concept that involves at least two related entities in order to make quantitative sense: a dimensionally defined category of objects "S" and any of its subsets "R". In essence "R" is a representation of "S"; it conveys representational (and hence, conceptual) information about "S". The amount of information that "R" conveys about "S " is equivalent to the rate of change in the complexity of "S" whenever the objects in "R" are removed from "S". Under this theory, the universal scientific constructs of pattern, invariance, complexity, representation, and information are unified under a novel mathematical framework.<ref name="VigoRepInfo">{{cite journal |url=http://www.sciencedirect.com/science/article/pii/S0020025511002696 |title=Representational information: a new general notion and measure of information |author=Vigo, Ronaldo |journal=Information Sciences |volume=181 |issue=21 |pages=4847–4859 |date=01 November 2011 |accessdate=12 September 2013 |doi=10.1016/j.ins.2011.05.020}}</ref><ref name="VigoCompUnc">{{cite journal |url=http://www.mdpi.com/2078-2489/4/1/1 |title=Complexity over Uncertainty in Generalized Representational Information Theory (GRIT): A Structure-Sensitive General Theory of Information |author=Vigo, Ronaldo |journal=Information |volume=4 |issue=1 |pages=01–30 |date=20 December 2012 |accessdate=12 September 2013 |doi=10.3390/info4010001}}</ref> Among other things, the framework aims to overcome the limitations of Shannon-Weaver information when attempting to characterize and measure subjective information.<br />

===As an influence which leads to a transformation===<br />
Information can also be defines as any type of pattern that influences the formation or transformation of other patterns.<ref>{{cite book|last=Shannon|first=Claude E.|title=The Mathematical Theory of Communication|year=1949}}</ref><ref>{{cite journal|last=Casagrande|first=David|title=Information as verb: Re-conceptualizing information for cognitive and ecological models|journal=Journal of Ecological Anthropology|year=1999|volume=3|issue=1|pages=4–13|url=http://www.lehigh.edu/~dac511/literature/casagrande1999.pdf}}</ref> In this sense, there is no need for a conscious mind to perceive, much less appreciate, the pattern.{{Citation needed|date=July 2010}} Consider, for example, [[DNA]]. The sequence of [[nucleotide]]s is a pattern that influences the formation and development of an organism without any need for a conscious mind.<br />
<br />
[[Systems theory]] at times seems to refer to information in this sense, assuming information does not necessarily involve any conscious mind, and patterns circulating (due to [[feedback]]) in the system can be called information. In other words, it can be said that information in this sense is something potentially perceived as representation, though not created or presented for that purpose. For example, [[Gregory Bateson]] defines "information" as a "difference that makes a difference".<ref>{{cite book|last=Bateson|first=Gregory|title=^ Form, Substance, and Difference, in Steps to an Ecology of Mind|year=1972|publisher=University of Chicago Press|pages=448–466}}</ref><br />
<br />
If, however, the premise of "influence" implies that information has been perceived by a conscious mind and also interpreted by it, the specific context associated with this interpretation may cause the transformation of the information into [[knowledge]]. Complex definitions of both "information" and "knowledge" make such semantic and logical analysis difficult, but the condition of "transformation" is an important point in the study of information as it relates to knowledge, especially in the business discipline of [[knowledge management]]. In this practice, tools and processes are used to assist a [[knowledge worker]] in performing research and making decisions, including steps such as:<br />
<br />
* reviewing information in order to effectively derive value and meaning<br />
* referencing [[metadata]] if any is available<br />
* establishing a relevant [[context (language use)|context]], often selecting from many possible contexts<br />
* deriving new knowledge from the information<br />
* making decisions or recommendations from the resulting knowledge.<br />
<br />
Stewart (2001) argues that the transformation of information into knowledge is a critical one, lying at the core of value creation and [[competitive advantage]] for the modern enterprise.<br />
<br />
The Danish Dictionary of Information Terms<ref>[http://www.informationsordbogen.dk/concept.php?cid=902 Informationsordbogen.dk]</ref> argues that information only provides an answer to a posed question. Whether the answer provides knowledge depends on the informed person. So a generalized definition of the concept should be: "Information" = An answer to a specific question".<br />
<br />
When [[Marshall McLuhan]] speaks of [[media (communication)|media]] and their effects on human cultures, he refers to the structure of [[cultural artifact|artifacts]] that in turn shape our behaviors and mindsets. Also, [[pheromone]]s are often said to be "information" in this sense.<br />
<br />
===As a property in physics===<br />
{{Main|Physical information}}<br />
Information has a well-defined meaning in physics. In 2003 [[J. D. Bekenstein]] claimed that a growing trend in [[physics]] was to define the physical world as being made up of information itself (and thus information is defined in this way) (see [[Digital physics]]). Examples of this include the phenomenon of [[quantum entanglement]], where particles can interact without reference to their separation or the speed of light. Information itself cannot travel faster than light even if the information is transmitted indirectly. This could lead to all attempts at physically observing a particle with an "entangled" relationship to another being slowed down, even though the particles are not connected in any other way other than by the information they carry.<br />
<br />
Another link is demonstrated by the [[Maxwell's demon]] thought experiment. In this experiment, a direct relationship between information and another physical property, [[entropy]], is demonstrated. A consequence is that it is impossible to destroy information without increasing the entropy of a system; in practical terms this often means generating heat. Another more philosophical outcome is that information could be thought of as interchangeable with [[Energy#Transformations of energy|energy]]{{citation needed|date=May 2013}}. Thus, in the study of [[logic gates]], the theoretical lower bound of thermal energy released by an ''AND gate'' is higher than for the ''NOT gate'' (because information is destroyed in an ''AND gate'' and simply converted in a ''NOT gate''). Physical information is of particular importance in the theory of [[quantum computers]].<br />

== Technologically mediated information ==<br />
It is estimated that the world's technological capacity to store information grew from 2.6 (optimally compressed) [[exabytes]] in 1986 – which is the informational equivalent to less than one 730-MB [[CD-ROM]] per person (539 MB per person) – to 295 (optimally compressed) [[exabytes]] in 2007.<ref name="HilbertLopez2011">[http://www.sciencemag.org/content/332/6025/60 "The World’s Technological Capacity to Store, Communicate, and Compute Information"], Martin Hilbert and Priscila López (2011), [[Science (journal)]], 332(6025), 60-65; free access to the article through here: martinhilbert.net/WorldInfoCapacity.html</ref> This is the informational equivalent of almost 61 [[CD-ROM]] per person in 2007.<ref name="Hilbertvideo2011">[http://www.youtube.com/watch?v=iIKPjOuwqHo "video animation on The World’s Technological Capacity to Store, Communicate, and Compute Information from 1986 to 2010]</ref><br />
<br />
The world’s combined technological capacity to receive information through one-way [[broadcast]] networks was the informational equivalent of 174 newspapers per person per day in 2007.<ref name="HilbertLopez2011"/><br />
<br />
The world's combined effective capacity to exchange information through two-way [[telecommunication]] networks was the informational equivalent of 6 newspapers per person per day in 2007.<ref name="Hilbertvideo2011"/><br />
<br />
== As records ==<br />
Records are specialized forms of information. Essentially, records are information produced consciously or as by-products of business activities or transactions and retained because of their value. Primarily, their value is as evidence of the activities of the organization but they may also be retained for their informational value. Sound [[records management]] ensures that the integrity of records is preserved for as long as they are required.<br />
<br />
The international standard on records management, ISO 15489, defines records as "information created, received, and maintained as evidence and information by an organization or person, in pursuance of legal obligations or in the transaction of business". The International Committee on Archives (ICA) Committee on electronic records defined a record as, "a specific piece of recorded information generated, collected or received in the initiation, conduct or completion of an activity and that comprises sufficient content, context and structure to provide proof or evidence of that activity".<br />
<br />
Records may be maintained to retain [[corporate memory]] of the organization or to meet legal, fiscal or accountability requirements imposed on the organization. Willis (2005) expressed the view that sound management of business records and information delivered "...six key requirements for good [[corporate governance]]...transparency; accountability; due process; compliance; meeting statutory and common law requirements; and security of personal and corporate information."<br />
<br />
== Information and semiotics ==<br />
[[Paul Beynon-Davies|Beynon-Davies]]<ref>Beynon-Davies P. (2002). Information Systems: an introduction to informatics in Organisations. Palgrave, Basingstoke, UK. ISBN 0-333-96390-3</ref><ref>Beynon-Davies P. (2009). Business Information Systems. Palgrave, Basingstoke. ISBN 978-0-230-20368-6</ref> explains the multi-faceted concept of information in terms of signs and signal-sign systems. Signs themselves can be considered in terms of four inter-dependent levels, layers or branches of [[semiotics]]: pragmatics, semantics, syntax, and empirics. These four layers serve to connect the social world on the one hand with the physical or technical world on the other...<br />
<br />
[[Pragmatics]] is concerned with the purpose of communication. Pragmatics links the issue of signs with the context within which signs are used. The focus of pragmatics is on the intentions of living agents underlying communicative behaviour. In other words, pragmatics link language to action.<br />
<br />
[[Semantics]] is concerned with the meaning of a message conveyed in a communicative act. Semantics considers the content of communication. Semantics is the study of the meaning of signs - the association between signs and behaviour. Semantics can be considered as the study of the link between symbols and their referents or concepts – particularly the way in which signs relate to human behavior.<br />
<br />
[[Syntax]] is concerned with the formalism used to represent a message. Syntax as an area studies the form of communication in terms of the logic and grammar of sign systems. Syntax is devoted to the study of the form rather than the content of signs and sign-systems.<br />
<br />
Empirics is the study of the signals used to carry a message; the physical characteristics of the medium of communication. Empirics is devoted to the study of communication channels and their characteristics, e.g., sound, light, electronic transmission etc..<br />
<br />
Nielsen (2008) discusses the relationship between semiotics and information in relation to dictionaries. The concept of [[lexicographic information cost]]s is introduced and refers to the efforts users of dictionaries need to make in order to, first, find the data sought and, secondly, understand the data so that they can generate information.<br />
<br />
Communication normally exists within the context of some social situation. The social situation sets the context for the intentions conveyed (pragmatics) and the form in which communication takes place. In a communicative situation intentions are expressed through messages which comprise collections of inter-related signs taken from a language which is mutually understood by the agents involved in the communication. Mutual understanding implies that agents involved understand the chosen language in terms of its agreed syntax (syntactics) and semantics. The sender codes the message in the language and sends the message as signals along some communication channel (empirics). The chosen communication channel will have inherent properties which determine outcomes such as the speed with which communication can take place and over what distance.<br />
