59-487: The library has 35 branches: It contains around 3 million digital information sources, including manuscripts , lithographic prints , movable type prints, historic documents , image sources , maps , and treatises . There is no information about the exact date of the establishment of the library of Asta- Quds - Razvi. Some consider the endowment date (974 AD) of the oldest Quran to the Holy Shrine of Imam Reza (AS) by

118-574: A knowledge worker in performing research and making decisions, including steps such as: Stewart (2001) argues that transformation of information into knowledge is critical, lying at the core of value creation and competitive advantage for the modern enterprise. In a biological framework, Mizraji has described information as an entity emerging from the interaction of patterns with receptor systems (eg: in molecular or neural receptors capable of interacting with specific patterns, information emerges from those interactions). In addition, he has incorporated

177-413: A signal ). It can also be encrypted for safe storage and communication. The uncertainty of an event is measured by its probability of occurrence. Uncertainty is inversely proportional to the probability of occurrence. Information theory takes advantage of this by concluding that more uncertain events require more information to resolve their uncertainty. The bit is a typical unit of information . It

236-435: A function must exist, even if it is not accessible for humans; A view surmised by Albert Einstein with the assertion that " God does not play dice ". Modern astronomy cites the mechanical sense of information in the black hole information paradox , positing that, because the complete evaporation of a black hole into Hawking radiation leaves nothing except an expanding cloud of homogeneous particles, this results in

295-449: A later development, with a computer used instead of several independent pieces of equipment. The Census Bureau first made limited use of electronic computers for the 1950 United States Census , using a UNIVAC I system, delivered in 1952. The term data processing has mostly been subsumed by the more general term information technology (IT). The older term "data processing" is suggestive of older technologies. For example, in 1996

354-444: A limited number of combinations could be recorded in one tally, so it was necessary to handle the schedules 5 or 6 times, for as many independent tallies." "It took over 7 years to publish the results of the 1880 census" using manual processing methods. The term automatic data processing was applied to operations performed by means of unit record equipment , such as Herman Hollerith 's application of punched card equipment for

413-434: A nutritional function. The cognitive scientist and applied mathematician Ronaldo Vigo argues that information is a concept that requires at least two related entities to make quantitative sense. These are, any dimensionally defined category of objects S, and any of its subsets R. R, in essence, is a representation of S, or, in other words, conveys representational (and hence, conceptual) information about S. Vigo then defines

472-465: A person called Ali Ibn Simjour, as the year of establishment date of the library of Asta- Quds - Razvi (or recitation place of Quran). It can also be assumed from some extant documents concerning the endowments that the library was open to the public and used by them in 1457 AD. From about 1737 AD, a special place was allocated to the library but a serious attention was paid to it in the early period of 20th century. However, an increasing inclination of using

531-553: 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". When Marshall McLuhan speaks of media and their effects on human cultures, he refers to the structure of artifacts that in turn shape our behaviors and mindsets. Also, pheromones are often said to be "information" in this sense. These sections are using measurements of data rather than information, as information cannot be directly measured. It

590-398: A type of input to an organism or system . Inputs are of two kinds; some inputs are important to the function of the organism (for example, food) or system ( energy ) by themselves. In his book Sensory Ecology biophysicist David B. Dusenbery called these causal inputs. Other inputs (information) are important only because they are associated with causal inputs and can be used to predict

649-901: Is entropy . Entropy quantifies the amount of uncertainty involved in the value of a random variable or the outcome of a random process . For example, identifying the outcome of a fair coin flip (with two equally likely outcomes) provides less information (lower entropy) than specifying the outcome from a roll of a die (with six equally likely outcomes). Some other important measures in information theory are mutual information , channel capacity, error exponents , and relative entropy . Important sub-fields of information theory include source coding , algorithmic complexity theory , algorithmic information theory , and information-theoretic security . Applications of fundamental topics of information theory include source coding/ data compression (e.g. for ZIP files ), and channel coding/ error detection and correction (e.g. for DSL ). Its impact has been crucial to

708-491: Is 'that which reduces uncertainty by half'. Other units such as the nat may be used. For example, the information encoded in one "fair" coin flip is log 2 (2/1) = 1 bit, and in two fair coin flips is log 2 (4/1) = 2 bits. A 2011 Science article estimates that 97% of technologically stored information was already in digital bits in 2007 and that the year 2002 was the beginning of the digital age for information storage (with digital storage capacity bypassing analogue for

767-421: Is a combination of machines , people, and processes that for a set of inputs produces a defined set of outputs . The inputs and outputs are interpreted as data , facts , information etc. depending on the interpreter's relation to the system. A term commonly used synonymously with data or storage (codes) processing system is information system . With regard particularly to electronic data processing ,

826-434: Is a major concept in both classical physics and quantum mechanics , encompassing the ability, real or theoretical, of an agent to predict the future state of a system based on knowledge gathered during its past and present. Determinism is a philosophical theory holding that causal determination can predict all future events, positing a fully predictable universe described by classical physicist Pierre-Simon Laplace as "

885-532: Is an uncountable mass noun . Information theory is the scientific study of the quantification , storage , and communication of information. The field itself was fundamentally established by the work of Claude Shannon in the 1940s, with earlier contributions by Harry Nyquist and Ralph Hartley in the 1920s. The field is at the intersection of probability theory , statistics , computer science, statistical mechanics , information engineering , and electrical engineering . A key measure in information theory

944-472: 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. This is the informational equivalent of almost 61 CD-ROM per person in 2007. The world's combined technological capacity to receive information through one-way broadcast networks

1003-431: Is expressed either as the content of a message or through direct or indirect observation . That which is perceived can be construed as a message in its own right, and in that sense, all information is always conveyed as the content of a message. Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs , or transmitted via

1062-416: Is forecast to increase rapidly, reaching 64.2 zettabytes in 2020. Over the next five years up to 2025, global data creation is projected to grow to more than 180 zettabytes. 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

1121-422: Is mainly (but not only, e.g. plants can grow in the direction of the light source) a causal input to plants but for animals it only provides information. The colored light reflected from a flower is too weak for photosynthesis but 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, which are causal inputs,

1180-421: Is not completely random and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analogue signals , poems , pictures , music or other sounds , and currents convey information in a more continuous form. Information is not knowledge itself, but

1239-460: Is the collection and manipulation of digital data to produce meaningful information. Data processing is a form of information processing , which is the modification (processing) of information in any manner detectable by an observer. Data processing may involve various processes, including: The United States Census Bureau history illustrates the evolution of data processing from manual through electronic procedures. Although widespread use of

SECTION 20

1298-487: Is the theoretical limit of compression. The information available through a collection of data may be derived by analysis. For example, a restaurant collects data from every customer order. That information may be analyzed to produce knowledge that is put to use when the business subsequently wants to identify the most popular or least popular dish. Information can be transmitted in time, via data storage , and space, via communication and telecommunication . Information

1357-642: The Data Processing Management Association (DPMA) changed its name to the Association of Information Technology Professionals . Nevertheless, the terms are approximately synonymous. Commercial data processing involves a large volume of input data, relatively few computational operations, and a large volume of output. For example, an insurance company needs to keep records on tens or hundreds of thousands of policies, print and mail bills, and receive and post payments. In science and engineering,

1416-512: The 1890 United States Census . "Using Hollerith's punchcard equipment, the Census Office was able to complete tabulating most of the 1890 census data in 2 to 3 years, compared with 7 to 8 years for the 1880 census. It is estimated that using Hollerith's system saved some $ 5 million in processing costs" in 1890 dollars even though there were twice as many questions as in 1880. Computerized data processing, or electronic data processing represents

1475-514: The meaning that may be derived from a representation through interpretation. The concept of information is relevant or connected to various concepts, including constraint , communication , control , data , form , education , knowledge , meaning , understanding , mental stimuli , pattern , perception , proposition , representation , and entropy . Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at

1534-435: 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. 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

1593-419: The amount of information that R conveys about S as the rate of change in the complexity of S whenever the objects in R are removed from S. Under "Vigo information", pattern, invariance, complexity, representation, and information – five fundamental constructs of universal science – are unified under a novel mathematical framework. Among other things, the framework aims to overcome

1652-401: 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 that signs relate to human behavior. 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

1711-413: The bank. A more sophisticated record keeping system might further identify the transactions— for example deposits by source or checks by type, such as charitable contributions. This information might be used to obtain information like the total of all contributions for the year. The important thing about this example is that it is a system , in which, all transactions are recorded consistently, and

1770-427: The biological order and participating in the development of multicellular organisms, precedes by millions of years the emergence of human consciousness and the creation of the scientific culture that produced the chemical nomenclature. 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

1829-403: The chosen language in terms of its agreed syntax 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 has inherent properties that determine outcomes such as the speed at which communication can take place, and over what distance. The existence of information about a closed system

1888-505: The complex are as follows: The number of manuscripts held by the library in 2003 was 30,250 volumes, 25,000 of earlier lithographic books, 17,240 other handwritten materials; 72,490 volumes in total. Affiliated with the library are eleven different museums which are located in different buildings near each other. They collectively form the Astan Quds Razavi Central Museum : The bureau of museums maintains an office for

1947-521: The computation and digital representation of data, and assists users in pattern recognition and anomaly detection . Information security (shortened as InfoSec) is the ongoing process of exercising due diligence to protect information, and information systems, from unauthorized access, use, disclosure, destruction, modification, disruption or distribution, through algorithms and procedures focused on monitoring and detection, as well as incident response and repair. Data processing Data processing

2006-415: The context of some social situation. The social situation sets the context for the intentions conveyed (pragmatics) and the form of communication. In a communicative situation intentions are expressed through messages that comprise collections of inter-related signs taken from a language mutually understood by the agents involved in the communication. Mutual understanding implies that agents involved understand

2065-439: The corresponding concept is referred to as electronic data processing system . A very simple example of a data processing system is the process of maintaining a check register. Transactions— checks and deposits— are recorded as they occur and the transactions are summarized to determine a current balance. Monthly the data recorded in the register is reconciled with a hopefully identical list of transactions processed by

2124-618: The domain and binary format of each number sequence before exchanging information. By defining number sequences online, this would be systematically and universally usable. Before the exchanged digital number sequence, an efficient unique link to its online definition can be set. This online-defined digital information (number sequence) would be globally comparable and globally searchable. The English word "information" comes from Middle French enformacion/informacion/information 'a criminal investigation' and its etymon, Latin informatiō(n) 'conception, teaching, creation'. In English, "information"

2183-401: The effect of its past and the cause of its future ". Quantum physics instead encodes information as a wave function , which prevents observers from directly identifying all of its possible measurements . Prior to the publication of Bell's theorem , determinists reconciled with this behavior using hidden variable theories , which argued that the information necessary to predict the future of

2242-486: The first time). Information can be defined exactly by set theory: "Information is a selection from the domain of information". The "domain of information" is a set that the sender and receiver of information must know before exchanging information. Digital information, for example, consists of building blocks that are all number sequences. Each number sequence represents a selection from its domain. The sender and receiver of digital information (number sequences) must know

2301-448: The formation and development of an organism without any need for a conscious mind. One might argue though that for a human to consciously define a pattern, for example a nucleotide, naturally involves conscious information processing. However, the existence of unicellular and multicellular organisms, with the complex biochemistry that leads, among other events, to the existence of enzymes and polynucleotides that interact maintaining

2360-401: The idea of "information catalysts", structures where emerging information promotes the transition from pattern recognition to goal-directed action (for example, the specific transformation of a substrate into a product by an enzyme, or auditory reception of words and the production of an oral response) The Danish Dictionary of Information Terms argues that information only provides an answer to

2419-895: The irrecoverability of any information about the matter to have originally crossed the event horizon , violating both classical and quantum assertions against the ability to destroy information. The information cycle (addressed as a whole or in its distinct components) is of great concern to information technology , information systems , as well as information science . These fields deal with those processes and techniques pertaining to information capture (through sensors ) and generation (through computation , formulation or composition), processing (including encoding, encryption, compression, packaging), transmission (including all telecommunication methods), presentation (including visualization / display methods), storage (such as magnetic or optical, including holographic methods ), etc. Information visualization (shortened as InfoVis) depends on

2478-403: 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. 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 –

2537-415: The library by the researches and scholars, prompted a faster growth to the library. Although the location of the library has been changed many times over years, it has always been remained in the vicinity of the Holy Shrine. The construction of the present building was completed in 1995, with a constructed area of 28,800 square meters and was opened to the public in 1995. Some of the outstanding features of

2596-411: The limitations of Shannon-Weaver information when attempting to characterize and measure subjective information. Information is any type of pattern that influences the formation or transformation of other patterns. In this sense, there is no need for a conscious mind to perceive, much less appreciate, the pattern. Consider, for example, DNA . The sequence of nucleotides is a pattern that influences

2655-438: 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. Pragmatics is concerned with the purpose of communication. Pragmatics links

2714-427: The next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information relevant to the phrase it is part of, each phrase conveys information relevant to the sentence it is part of, and so on until at the final step information is interpreted and becomes knowledge in a given domain . In a digital signal , bits may be interpreted into

2773-436: The occurrence of a causal input at a later time (and perhaps another place). Some information is important because of association with other information but eventually there must be 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 can be functional to the organism or system. For example, light

2832-594: The organization or to meet legal, fiscal or accountability requirements imposed on the organization. Willis 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." Michael Buckland has classified "information" in terms of its uses: "information as process", "information as knowledge", and "information as thing". Beynon-Davies explains

2891-565: The preservation and repair of historical objects of the Museum and library by a technical staff of specialists. 36°18′54″N 59°29′22″E  /  36.3150°N 59.4894°E  / 36.3150; 59.4894 Information Information is an abstract concept that refers to something which has the power to inform . At the most fundamental level, it pertains to the interpretation (perhaps formally ) of that which may be sensed , or their abstractions . Any natural process that

2950-471: 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

3009-418: The study of the form rather than the content of signs and sign systems. Nielsen (2008) discusses the relationship between semiotics and information in relation to dictionaries. He introduces the concept of lexicographic information costs and refers to the effort a user of a dictionary must make to first find, and then understand data so that they can generate information. Communication normally exists within

3068-715: The success of the Voyager missions to deep space, the invention of the compact disc , the feasibility of mobile phones and the development of the Internet. The theory has also found applications in other areas, including statistical inference , cryptography , neurobiology , perception , linguistics, the evolution and function of molecular codes ( bioinformatics ), thermal physics , quantum computing , black holes , information retrieval , intelligence gathering , plagiarism detection , pattern recognition , anomaly detection and even art creation. Often information can be viewed as

3127-512: The symbols, letters, numbers, or structures that convey the information available at the next level up. The key characteristic of information is that it is subject to interpretation and processing. The derivation of information from a signal or message may be thought of as the resolution of ambiguity or uncertainty that arises during the interpretation of patterns within the signal or message. Information may be structured as data . Redundant data can be compressed up to an optimal size, which

3186-434: 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". If, however, the premise of "influence" implies that information has been perceived by a conscious mind and also interpreted by it,

3245-402: The term data processing dates only from the 1950s, data processing functions have been performed manually for millennia. For example, bookkeeping involves functions such as posting transactions and producing reports like the balance sheet and the cash flow statement . Completely manual methods were augmented by the application of mechanical or electronic calculators . A person whose job

3304-683: The terms data processing and information systems are considered too broad, and the term data processing is typically used for the initial stage followed by a data analysis in the second stage of the overall data handling. Data analysis uses specialized algorithms and statistical calculations that are less often observed in a typical general business environment. For data analysis, software suites like SPSS or SAS , or their free counterparts such as DAP , gretl , or PSPP are often used. These tools are usually helpful for processing various huge data sets, as they are able to handle enormous amount of statistical analysis. A data processing system

3363-416: The transaction of business". The International Committee on Archives (ICA) Committee on electronic records defined a record as, "recorded information produced or received in the initiation, conduct or completion of an institutional or individual activity and that comprises content, context and structure sufficient to provide evidence of the activity". Records may be maintained to retain corporate memory of

3422-443: Was the informational equivalent of 174 newspapers per person per day in 2007. 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. As of 2007, an estimated 90% of all new information is digital, mostly stored on hard drives. The total amount of data created, captured, copied, and consumed globally

3481-535: Was to perform calculations manually or using a calculator was called a " computer ." The 1890 United States Census schedule was the first to gather data by individual rather than household . A number of questions could be answered by making a check in the appropriate box on the form. From 1850 to 1880 the Census Bureau employed "a system of tallying, which, by reason of the increasing number of combinations of classifications required, became increasingly complex. Only
