inflection
  درچفتش

influence
  ۱) هنایش؛ ۲) هناییدن   
1) hanâyeš (#) ; 2) hanâyidan (#)

Fr.: 1) influence; 2) influencer, influer   

1) The act or power of producing an → effect, especially inconspicuously; the effect of power exerted.
2) To have or exert influence on; affect.

M.E., from O.Fr. influence, from L. influentia "stellar emanation" (it was thought an ethereal liquid flowed from the stars and affected the destiny of humans), also "a flow of water, a flowing in," from L. influentem (nominative influens), pr.p. of influere "to flow into," from → in- "into, in, on, upon" + fluere "to flow;" PIE base *bhleu- "to swell, overflow;" cf. Gk. phluein "to boil over, bubble up," phlein "to abound."

Hanâyeš "influence" (Borhân-e Qâte'; Kasravi). We suggest the following origin for this word: ultimately from Proto-Ir. *ha-nai "to conduct, direct, guide, lead," from *ham-naiH-, from prefix *ham- "together," also an intensive prefix, → com-, + *naiH- "to lead, conduct, guide;" cf. Av. naii- (naŷ-) "to lead, guide," naiieiti "leads;" O.Pers. nay- "to lead, bring" anaya "leads;" Mid.Pers. nidan, ônidan, nay- "to lead, bring;" Sogd. n'y- "to lead;" Choresmian (prefixed, + *apa-) bny- "to remove;" Skt. nī- "to lead," náyati "leads." In dialects: Anâraki niye "to bring, lead;" Kurd. (prefixed) ânin, inân, (with prefix ham-) hânin, hênân "to bring, lead to," Tâleši ânân, ânoe "to bring together two edges;" Zazaki ân- "to bring;" Qohrudi hunda, hun- "to bring, lead;" Târi niya-, neg- "to lead;" Lasgardi (prefixed) bin- "to bring, carry;" Qomi niyé, Tafreši neyé "a jab or poke used for leading the cattle;" see also → relate.

inform
  ازداییدن   
azdâyidan (#)

Fr.: informer   

1) To impart → knowledge of a fact or circumstance.
2) To supply (oneself) with knowledge of a matter or subject (dictionary.com).
3) To convey → information.
See also: → informatics, → information theory.

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
  ازداینده   
azdâyandé

Fr.: informateur   

A person who gives → information.

From → inform + -ant a suffix forming adjectives and nouns from verbs.

informatics
  ازداییک   
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
  ازدایش   
azdâyeš (#)

Fr.: information   

1) Knowledge gained through study, communication, research, instruction, etc.
2) Knowledge communicated or received concerning a particular fact or circumstance; news.
3) The act or fact of informing.
4) A sequence of signals that conveys a message to a receiver. Information does not exist on its own. It is contained within something and is coded. The notion of information involves → uncertainty and → randomness; hence the necessity for calling on → probability theory and → statistics.
See also: → information content, → information entropy, → information flow, → information paradox, → information science, → information technology, → information theory, → infosphere, → quantum information, → entropy.

Verbal noun of → inform.

information content
  پربنه‌ی ِ ازدایش   
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
  درگاشت ِ ازدایش   
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
  تچان ِ ازدایش   
tacân-e azdâyeš

information paradox
  پارادخش ِ ازدایش   
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
  دانش ِ ازدایش، ازداییک   
dâneš-e azdâyeš azdâyik (#)

Fr.: informatique

information theory
  نگره‌ی ِ ازدایش   
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.
