Example Input: Context: An anode is an electrode through which conventional current flows into a polarized electrical device. A common mnemonic is ACID for "anode current into device". The direction of (positive) electric current is opposite to the direction of electron flow: (negatively charged) electrons flow out the anode to the outside circuit., An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words "elektron", meaning amber (from which the word electricity is derived), and "hodos", a way., Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high electrical resistance   higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics., Silicon is a chemical element with symbol Si and atomic number 14. A hard and brittle crystalline solid with a blue-gray metallic luster, it is a tetravalent metalloid. It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, lead, and flerovium below. It is rather unreactive, though less so than germanium, and has great chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by Jöns Jakob Berzelius., Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit., Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium. It rarely occurs in its elemental state or as pure ore compounds in the Earth's crust. Selenium (Greek  "selene" meaning "Moon") was discovered in 1817 by Jöns Jacob Berzelius, who noted the similarity of the new element to the previously discovered tellurium (named for the Earth)., An intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p., Germanium is a chemical element with symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature. Unlike silicon, it is too reactive to be found naturally on Earth in the free (elemental) state., A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification., In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a pn junction connected to two electrical terminals. A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. Semiconductor diodes were the first semiconductor electronic devices. The discovery of crystals' rectifying abilities was made by German physicist Ferdinand Braun in 1874. The first semiconductor diodes, called cat's whisker diodes, developed around 1906, were made of mineral crystals such as galena. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used., A pn junction is a boundary or interface between two types of semiconductor material, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons. The p-n junction is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with one type of dopant on top of a layer of crystal doped with another type of dopant). If two separate pieces of material were used, this would introduce a grain boundary between the semiconductors that would severely inhibit its utility by scattering the electrons and holes., Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver., Vacuum is space void of matter. The word stems from the Latin adjective "vacuus" for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a "perfect" vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object that is surrounded by a vacuum., A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) to alter the electrical or optical properties of the substance. In the case of crystalline substances, the atoms of the dopant very commonly take the place of elements that were in the crystal lattice of the base material. The crystalline materials are frequently either crystals of a semiconductor such as silicon and germanium for use in solid-state electronics, or transparent crystals for use in the production of various laser types; however, in some cases of the latter, noncrystalline substances such as glass can also be doped with impurities., An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components., The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, "". As it is a fermion, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a larger De Broglie wavelength for a given energy., In physics, a charge carrier is a particle free to move, carrying an electric charge, especially the particles that carry electric charges in electrical conductors. Examples are electrons, ions and holes. In a conducting medium, an electric field can exert force on these free particles, causing a net motion of the particles through the medium; this is what constitutes an electric current. In different conducting media, different particles serve to carry charge:, In electronics, a vacuum tube, an electron tube, or just a tube (North America), or valve (Britain and some other regions), is a device that controls electric current between electrodes in an evacuated container.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all electronic circuit valves/electron tubes are vacuum tubes (evacuated); gas-filled tubes are similar devices containing a gas, typically at low pressure, which exploit phenomena related to electric discharge in gases, usually without a heater., A cathode is the electrode from which a conventional current leaves a polarized electrical device. (This definition can be recalled by using the mnemonic "CCD" for "cathode current departs".) A conventional current describes the direction in which positive electronic charges move. Electrons have a negative charge, so the movement of electrons is opposite to the conventional current flow. Consequently, the mnemonic "cathode current departs" also means that electrons flow into the device's cathode., A PIN diode is a diode with a wide , undoped intrinsic semiconductor region between a p - type semiconductor and an n - type semiconductor region . The p - type and n - type regions are typically heavily doped because they are used for ohmic contacts . The wide intrinsic region is in contrast to an ordinary PN diode . The wide intrinsic region makes the PIN diode an inferior rectifier ( one typical function of a diode ) , but it makes the PIN diode suitable for attenuators , fast switches , photodetectors , and high voltage power electronics applications ., Subject: pin diode, Relation: instance_of, Options: (A) approximation (B) base (C) behavior (D) case (E) charge (F) chemical (G) chemical element (H) component (I) conductor (J) constant (K) crystal (L) diode (M) direction (N) electric current (O) electrode (P) electron (Q) electronic circuit (R) electronic component (S) electronics (T) force (U) formation (V) generation (W) group (X) interface (Y) junction (Z) laboratory ([) laser (\) mass (]) material (^) member (_) metal (`) mineral (a) mnemonic (b) motion (c) negative (d) ore (e) part (f) particle (g) physics (h) principle (i) process (j) role (k) semiconductor (l) semiconductor diode (m) side (n) single (o) space (p) state (q) structure (r) study (s) symbol (t) system (u) temperature (v) test (w) word

Example Input: Context: The Godfather Returns is a novel written by author Mark Winegardner, published in 2004. It is the sequel to Mario Puzo's "The Godfather", which was originally published in 1969, and "The Sicilian" (1984). The publisher, Random House, selected Winegardner to write a sequel after Puzo's death. As the original novel covered the years 1945 to 1955, and included significant back story on Don Vito Corleone's life, "Returns" covers the years 1955 to 1962, and includes significant back story on Michael Corleone's life prior to the first novel., Vito Andolini Corleone is a fictional character in Mario Puzo's novel "The Godfather" and in Francis Ford Coppola's film series based on the novel, where he was portrayed by Marlon Brando in "The Godfather" and, as a young man, by Robert De Niro in "The Godfather Part II"., Mark Winegardner (born November 24, 1961) is an American writer born and raised in Bryan, Ohio. His novels include "The Godfather Returns", "Crooked River Burning", and "The Veracruz Blues". He published a collection of short stories, "That's True of Everybody", in 2002. His newest novel, "The Godfather's Revenge", was published in November 2006 by Putnam. His "Godfather" novels continue the story of the Corleone family depicted in Mario Puzo's "The Godfather"., Mario Gianluigi Puzo (October 15, 1920  July 2, 1999) was an American author, screenwriter and journalist of Italian descent. He is known for his crime novels about the Mafia, most notably "The Godfather" (1969), which he later co-adapted into a three-part film saga directed by Francis Ford Coppola. He received the Academy Award for Best Adapted Screenplay for the first film in 1972 and "Part II" in 1974. Puzo also wrote the original screenplay for the 1978 "Superman" film. His last novel, "The Family", was released posthumously in 2001., Organized crime is a category of transnational, national, or local groupings of highly centralized enterprises run by criminals who intend to engage in illegal activity, most commonly for money and profit. Some criminal organizations, such as terrorist groups, are politically motivated. Sometimes criminal organizations force people to do business with them, such as when a gang extorts money from shopkeepers for so-called "protection". Gangs may become disciplined enough to be considered "organized". A criminal organization or gang can also be referred to as a mafia, mob, or crime syndicate; the network, subculture and community of criminals may be referred to as the underworld., Bryan is a city in and the county seat of Williams County, Ohio, United States, in the state's northwestern corner. The population was 8,545 at the 2010 census., The Godfather's Revenge, a 2006 novel written by author Mark Winegardner, is the sequel to "The Godfather", "The Sicilian", and "The Godfather Returns". The story takes place from 19631964, and picks up the story from where "The Godfather Returns" left off. The novel deals with Michael Corleone's guilt over the events of "The Godfather Part II", particularly his ordering the death of his brother, Fredo. Subplots include Nick Geraci's plans for revenge against the Corleones, Tom Hagen's being implicated in a murder, and organized crime's battle with a presidential family (the Sheas, who are analogous to the Kennedy family)., The Sicilian is a novel by Italian-American author Mario Puzo. Published in 1984 by Random House Publishing Group (ISBN 0-671-43564-7), it is based on Puzo's most famous work, "The Godfather". It is regarded as "The Godfather"'s literary sequel., Random House is the largest general-interest paperback publisher in the world. 
As of 2013, it is part of Penguin Random House, which is jointly owned by German media conglomerate Bertelsmann and British global education and publishing company Pearson PLC., The Godfather Part II is a 1974 American crime film produced and directed by Francis Ford Coppola from a screenplay co-written with Mario Puzo, starring Al Pacino and Robert De Niro. Partially based on Puzo's 1969 novel "The Godfather", the film is both sequel and prequel to "The Godfather", presenting parallel dramas: one picks up the 1958 story of Michael Corleone (Pacino), the new Don of the Corleone crime family, protecting the family business in the aftermath of an attempt on his life; the prequel covers the journey of his father, Vito Corleone (De Niro), from his Sicilian childhood to the founding of his family enterprise in New York City., Tom Hagen is a fictional character in Mario Puzo's novel "Godfather" and Francis Ford Coppola's films "The Godfather" and "The Godfather Part II".

Example Input: Context: In computing, directory service or name service maps the names of network resources to their respective network addresses. It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects. A directory service is a critical component of a network operating system. A directory server is a server which provides such a service. Each resource on the network is considered an object by the directory server. Information about a particular resource is stored as a collection of attributes associated with that resource or object. , Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection., Microsoft Servers (previously called "Windows Server System") is a brand that encompasses Microsoft's server products. This includes the Windows Server editions of the Microsoft Windows operating system itself, as well as products targeted at the wider business market. Unlike Microsoft Dynamics or Microsoft Office product lines, most of the products sold under this brand are not intended to be line-of-business services in and of themselves., rsync is a utility that keeps copies of a file on two computer systems. It is commonly found on Unix-like systems and functions as both a file synchronization and file transfer program. The rsync algorithm is a type of delta encoding, and is used for minimizing network usage. Zlib may be used for additional compression, and SSH or stunnel can be used for data security., On Microsoft Servers, a domain controller (DC) is a server computer that responds to security authentication requests (logging in, checking permissions, etc.) within a Windows domain. A "domain" is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination., In computing, a file server (or fileserver) is a computer attached to a network that has the primary purpose of providing a location for shared disk access, i.e. shared storage of computer files (such as documents, sound files, photographs, movies, images, databases, etc.) that can be accessed by the workstations that are attached to the same computer network. The term "server" highlights the role of the machine in the clientserver scheme, where the "clients" are the workstations using the storage. A file server is not intended to perform computational tasks, and does not run programs on behalf of its clients.
It is designed primarily to enable the storage and retrieval of data while the computation is carried out by the workstations., Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was only in charge of centralized domain management. Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services., Microsoft Corporation (commonly referred to as Microsoft or MS) is an American multinational technology company headquartered in Redmond, Washington, that develops, manufactures, licenses, supports and sells computer software, consumer electronics and personal computers and services. Its best known software products are the Microsoft Windows line of operating systems, Microsoft Office office suite, and Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface tablet lineup. As of 2016, it was the world's largest software maker by revenue, and one of the world's most valuable companies., Microsoft Windows (or simply Windows) is a metafamily of graphical operating systems developed, marketed, and sold by Microsoft. It consists of several families of operating systems, each of which cater to a certain sector of the computing industry with the OS typically associated with IBM PC compatible architecture. Active Windows families include Windows NT, Windows Embedded and Windows Phone; these may encompass subfamilies, e.g. Windows Embedded Compact (Windows CE) or Windows Server. Defunct Windows families include Windows 9x; Windows 10 Mobile is an active product, unrelated to the defunct family Windows Mobile., Windows Phone (WP) is a family of mobile operating systems developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone features a new user interface derived from Metro design language. Unlike Windows Mobile, it is primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010 with Windows Phone 7. Windows Phone 8.1 is the latest public release of the operating system, released to manufacturing on April 14, 2014., Samba is a free software re-implementation of the SMB / CIFS networking protocol , and was originally developed by Andrew Tridgell . Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain , either as a Domain Controller ( DC ) or as a domain member . As of version 4 , it supports Active Directory and Microsoft Windows NT domains . Samba runs on most Unix , OpenVMS and Unix - like systems , such as Linux , Solaris , AIX and the BSD variants , including Apple 's OS X Server , and OS X client ( version 10.2 and greater ) . Samba is standard on nearly all distributions of Linux and is commonly included as a basic system service on other Unix - based operating systems as well . Samba is released under the terms of the GNU General Public License . The name Samba comes from SMB ( Server Message Block ) , the name of the standard protocol used by the Microsoft Windows network file system ., Andrew "Tridge" Tridgell (born 28 February 1967) is an Australian computer programmer. He is the author of and a contributor to the Samba file server, and co-inventor of the rsync algorithm., A Windows domain is a form of a computer network in which all user accounts, computers, printers and other security principals, are registered with a central database located on one or more clusters of central computers known as domain controllers. Authentication takes place on domain controllers. Each person who uses computers within a domain receives a unique user account that can then be assigned access to resources within the domain. Starting with Windows 2000, Active Directory is the Windows component in charge of maintaining that central database. The concept of Windows domain is in contrast with that of a workgroup in which each computer maintains its own database of security principals., Samba is a Brazilian musical genre and dance style, with its roots in Africa via the West African slave trade and African religious traditions, particularly of Angola and the Congo, through the samba de roda genre of the northeastern state of Bahia, from which it derived. Although there were various forms of samba in Brazil in the form of various popular rhythms and regional dances that originated from drumming, samba as a music genre is seen as originally a musical expression of urban Rio de Janeiro, then the capital and largest city of Imperial Brazil., Subject: samba , Relation: use, Options: (A) authentication (B) computer network (C) environmental protection (D) industry (E) language (F) music (G) office (H) security (I) service (J) storage (K) synchronization (L) trade
