bioinformatics zist-azdâyik Fr.: bioinformatique The retrieval and analysis of biochemical and biological data using mathematics and computer science, as in the study of genomes (Dictionary.com). → bio-; → informatics. |
inform azdâyidan (#) Fr.: informer 1) To impart → knowledge of a fact or circumstance. Inform, from M.E. informen, from O.Fr. enformer, from L. informare "to shape, form; to form an idea of," from → in- "into" + → forma "form." Azdâyidan, from Mid.Pers. azdênidan "to inform," from azd "information, proclamation; known" (loaned into Arm. azd), from O.Pers. azdā "known," azdā kar "to become known;" Av. azdā "known;" Sogdian 'zd' "informed, known;" cf. Skt. addhā' "manifestly; certainly, truly," addhāti "sage." |
informant azdâyandé Fr.: informateur A person who gives → information. From → inform + -ant a suffix forming adjectives and nouns from verbs. |
informatics azdâyik (#) Fr.: informatique The science concerned with gathering, manipulating, storing, retrieving, and classifying recorded → information. Also called → information science, computer science. Informatics, from informat(ion), → information + → ics. |
information azdâyeš (#) Fr.: information 1) Knowledge gained through study, communication, research, instruction, etc. Verbal noun of → inform. |
information content parbane-ye azdâyeš Fr.: contenu d'information The → negative of the → logarithm of the → probability that a particular → message or → symbol will be emitted by a → source. → information; → content. |
information entropy dargâšt-e azdâyeš Fr.: entropie de l'information The measure of information, which is usually expressed by the average number of bits needed for storage or communication. In other words, the degree to which the values of a → random variable X are dispersed. If the → probability density function of X is P(x), the entropy is defined by: H(X) = -Σ P(x) log P(x). Also called → Shannon entropy. → information; → entropy. |
information flow tacân-e azdâyeš Fr.: flot d'information The flow of data into a system or to the end users. → information; → flow. |
information paradox pârâdaxš-e azdâyeš Fr.: paradoxe de l'information A paradox raised in 1976 by S. Hawking (1942-2018) whose analysis of the thermodynamic properties of → black holes led him to the prediction that black holes are not in fact black, but radiate due to quantum effects. This implied that, due to the → Hawking radiation, a black hole would eventually evaporate away, leaving nothing. This deduction presented a problem for → quantum mechanics, which maintains that information can never be lost. This topic is a matter of intense debate. Many solutions have been proposed, but all of them have serious drawbacks. In order to analyze better these solutions one needs a quantum gravity theory, which does not exist at the moment. In brief, either the idea of → quantum unitarity must be given up, or a mechanism should be found by which information is not lost after it falls into a black hole. → information; → paradox. |
information science dâneš-e azdâyeš azdâyik (#) Fr.: informatique Same as → informatics. → information; → science. |
information technology tašnik-šenâsi-ye azdâyeš Fr.: technologie de l'informtion The science and activity of receiving, storing, processing, and transmitting information by using → computers. → information; → technology. |
information theory negare-ye azdâyeš (#) Fr.: théorie de l'information The mathematical theory that defines, quantifies,
and analyzes the concept of → information.
It involves → probability theory in
→ transmission of → messages
when the → bits of information are subject to various
distortions. Its goal is to enable as much information as possible to be reliably
stored on a medium, retrieved, or communicated. → information; → theory. |
informative azdâmand Fr.: informatif Giving → information, providing information, imparting → knowledge. |
informer azdâgar Fr.: informateur A person who provides → information. |
quantum information azdâyeš-e kuântomi Fr.: information quantique The science concerned with the transmission, storage, and processing of information using quantum mechanical systems. It exploits the notion of → quantum entanglement between systems and joins several fields of knowledge, mainly quantum physics, information, computation, and probability. → quantum; → information. |
