Fidelity is the quality of being faithful or loyal. Its original meaning regarded duty Duty is a term that conveys a sense of moral commitment to someone or something. The moral commitment is the sort that results in action[citation needed] and it is not a matter of passive feeling or mere recognition. When someone recognizes a duty, that person commits himself/herself to the cause involved without considering the self-interested to a lord Lord is a title with various meanings. It can denote a prince or a feudal superior . The title today is mostly used in connection with the peerage of the United Kingdom or its predecessor countries, although some users of the title do not themselves hold peerages, and use it 'by courtesy'. The title may also be used in conjunction with others to or a king A Monarch is the person who heads a monarchy, a form of government in which a country or entity is usually ruled or controlled by an individual who normally rules for life or until abdication. Monarchs may be autocrats or may be ceremonial heads of state who exercise little or no power or only reserve power, with actual authority vested in a, in a broader sense than the related concept of fealty An oath of fealty, from the Latin fidelitas , is a pledge of allegiance of one person to another. Typically the oath is made upon a religious object such as a Bible or saint's relic, thus binding the oath-taker before God. Both derive from the Latin Latin or sometimes Roman is an Italic language originally spoken in Latium and Ancient Rome. Although often considered a dead language, in view of the fact that it has no native, fluent speakers, Latin continues to be taught in schools and has been, and currently is, used in the process of new word production in modern languages from many word fidēlis (A III adjective), meaning "faithful or loyal"
In modern human Humans are a species of animal known taxonomically as Homo sapiens , and are the only extant member of the Homo genus of bipedal primates in Hominidae, the great ape family. However, in some cases "human" is used to refer to any member of the genus Homo relationships An interpersonal relationship is an association between two or more people that may range from fleeting to enduring. This association may be based on limerence, love and liking, regular business interactions, or some other type of social commitment. Interpersonal relationships take place in a great variety of contexts, such as family, friends,, the term can refer to sexual monogamy Monogamy usually refers to a form of marriage in which an individual has only one spouse at any one time. However, monogamy may also refer to the more general state of having only one mate at any one time and as such may be applied to the social behavior of all animals. In current usage monogamy often refers to having one sexual partner. In western culture this often means adherence to marriage Marriage is a social union or legal contract between individuals that creates kinship. It is an institution in which interpersonal relationships, usually intimate and sexual, are acknowledged in a variety of ways, depending on the culture or subculture in which it is found. Such a union may also be called matrimony, while the ceremony that marks vows, or of promises of exclusivity or monogamy, and an absence of adultery. However, some people do not equate fidelity in personal relationships with sexual or emotional monogamy. (For example, see polyamory and Open marriage Open marriage typically refers to a marriage in which the partners agree that each may engage in extramarital sexual relationships, without this being regarded as infidelity. There are many different styles of open marriage, with the partners having varying levels of input on their spouse's activities.) Often, however, females in Shakespeare William Shakespeare [a] was an English poet and playwright, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon".[b] His surviving works, including some collaborations, consist of about 38 plays,[c] 154 sonnets, two long are associated with it in a negative sense, such as "She is with little fidelity". For example, Bertram accuses Helena of having "little fidelity" in All's Well That Ends Well All's Well That Ends Well is a play by William Shakespeare. It was probably written between 1601 and 1608, and it was first published in the First Folio in 1623.
Fidelity also denotes how accurate a copy is to its source. For example, a worn gramophone record A gramophone record, commonly known as phonograph record , vinyl record (when made of polyvinyl chloride), or simply record, is an analog sound storage medium consisting of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the centre of the disc. Phonograph records are generally will have a lower fidelity than one in good condition, and a recording made by a low budget record company in the early 20th century is likely to have significantly less audio fidelity than a good modern recording. In the 1950s, the terms "high fidelity High fidelity—or hi-fi—reproduction is a term used by home stereo listeners and home audio enthusiasts to refer to high-quality reproduction of sound or images. Ideally, high-fidelity equipment has minimal amounts of noise and distortion and an accurate frequency response as set out in 1973 by the German Deutsches Institut für Normung (DIN)" or "hi-fi" were popularized for equipment and recordings which exhibited more accurate sound reproduction Sound recording and reproduction is an electrical or mechanical inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a small microphone diaphragm that. The converse term "lo-fi Low fidelity or lo-fi describes a sound recording which contains technical flaws such as distortion, hum, or background noise, or limited frequency response. The term "low-fidelity" is used in contrast to the audiophile term high fidelity or "hi-fi", which refers to stereo equipment that very accurately reproduces music without", doesn't necessarily mean "low fidelity", rather that the production ethic aims for " gritty authenticity" over perfect production. Similarly in electronics Electronics is the branch of science and technology which makes use of the controlled motion of electrons through different media and vacuum. The ability to control electron flow is usually applied to information handling or device control. Electronics is distinct from electrical science and technology, which deals with the generation,, fidelity refers to the correspondence of the output signal to the input signal, rather than sound quality.
In the fields of scientific modelling Scientific modelling is the process of generating abstract, conceptual, graphical and/or mathematical models. Science offers a growing collection of methods, techniques and theory about all kinds of specialized scientific modelling. Also a way to read elements easily which have been broken down to the simplest form and simulation Simulation is used in many contexts, including the modeling of natural systems or human systems in order to gain insight into their functioning. Other contexts include simulation of technology for performance optimization, safety engineering, testing, training and education. Simulation can be used to show the eventual real effects of alternative, fidelity refers to the degree to which a model or simulation reproduces the state and behaviour of a real world object, feature or condition. Fidelity is therefore a measure of the realism of a model or simulation[1]. Simulation fidelity has also been described in the past as 'degree of similarity'[2].
The computer age has spawned the term Wi-Fi Wi-Fi is a trademark of the Wi-Fi Alliance that manufacturers may use to brand certified products that belong to a class of wireless local area network (WLAN) devices based on the IEEE 802.11 standards, which is by far the most widespread WLAN class today. Because of the close relationship with its underlying standard, the term Wi-Fi is often used in reference to certain groups of wireless Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires". The distances involved may be short or long (thousands or millions of kilometers for radio communications). When the context is clear, the term is often shortened to "wireless". Wireless electronic devices. While the term Wi-Fi has been popularly taken to be an abbreviation of 'wireless fidelity', Wi-Fi is in fact a commercial brand owned by the Wi-Fi Alliance The Wi-Fi Alliance is a trade group that owns the trademark Wi-Fi, and has nothing to do with fidelity as a concept.
In the field of program evaluation Program evaluation is a systematic method for collecting, analyzing, and using information to answer basic questions about projects, policies and programs. Program evaluation is used in the public and private sector and is taught in numerous universities. Evaluation became particularly relevant in the U.S. in the 1960s during the period of the, the term fidelity denotes how closely a set of procedures were implemented as they were supposed to have been. For example, it's difficult to draw conclusions from a study about formative assessment in school classrooms if the teachers are not able or willing to follow the procedures they received in training.[3]
