Service (systems architecture)In the contexts of software architecture, service is a set of software functionality (such as the retrieval of specified information or the execution of a set of operations) that different clients can reuse, together with the policies that should control its usage (based on the identity of the client requesting the service, for example).Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.MiddlewareMiddleware is a type of computer software program that provides services to software applications beyond those available from the operating system. It can be described as "software glue". Middleware makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application.System resourceA computersystem resource is any hardware or software aspect of limited availability that is accessible to a computer system. Like any resource, computer system resources can be exhausted, and issues arise due to scarcity. Resource management, a key aspect of designinghardware and software, includes preventing resource leaks (not releasing a resource done with it) and handling resource contention (when multiple processes want to access the same resource).
ReplicaA replica is an exact (usually 1:1 in scale) copy or remake of an object, made out of the same raw materials, whether a work of art, or a commercial product. The term is also used for copies that closely resemble the original, without claiming to be identical. Copies or reproductions of documents, books, manuscripts, maps or art prints are called facsimiles. Replicas have been sometimes sold as originals, a type of fraud. Most replicas have more innocent purposes.
CERNEuropean particle physics research centreThe European Organization for Nuclear Research, also called European Laboratory for Particle Physics, known as CERN (; French pronunciation:; Organisation européenne pour la recherche nucléaire), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, a western suburb of Geneva, on the France–Switzerland border.
Large Hadron ColliderThe Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator as of 2026. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008, in collaboration with over 10,000 scientists, and hundreds of universities and laboratories across more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
Application softwareApplication software is software that is intended for end-user use – not operating, administering or programming a computer. It includes programs such as word processors, web browsers, media players, and mobile applications used in daily tasks. An application (app, application program, software application) is any program that can be categorized as application software.
DataData ( DAY-tə, US also DAT-ə) is a collection of discrete or continuous values that conveys information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum, data value or data point is an individual value in a collection of data.
Data setA data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files.
Administrative domainAn administrative domain is a service provider holding a securityrepository permitting to easily authenticate and authorizeclients with credentials. This particularly applies to computer network security. This concept is captured by the 'AdminDomain' class of the GLUE information model. An administrative domain is mainly used in intranet environments.ArchitectureArt and technique of designing buildingsIn adding the dome to the Florence Cathedral (Italy) in the early 15th century, the architect Filippo Brunelleschi not only transformed the building and the city, but also the role and status of the architect.Bauhaus building (Germany).
