Hypostatic abstractionHypostatic abstraction in mathematical logic, also known as hypostasis or subjectal abstraction, is a formal operation that transforms a predicate into a relation; for example "Honey is sweet" is transformed into "Honey has sweetness". The relation is created between the original subject and a new term that represents the property expressed by the original predicate. Hypostasis changes a propositional formula of the form X is Y to another one of the form X has the property of being Y or X has Y-ness.
Distributed computingA distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another. Distributed computing is a field of computer science that studies distributed systems. The components of a distributed system interact with one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the lack of a global clock, and managing the independent failure of components.
Abstraction layerIn computing, an abstraction layer or abstraction level is a way of hiding the working details of a subsystem. Examples of software models that use layers of abstraction include the OSI model for network protocols, OpenGL, and other graphics libraries, which allow the separation of concerns to facilitate interoperability and platform independence. Another example is Media Transfer Protocol. In computer science, an abstraction layer is a generalization of a conceptual model or algorithm, away from any specific implementation.
Simple Network Management ProtocolSimple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behaviour. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and more. SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB), which describes the system status and configuration.
Lyrical abstractionLyrical abstraction is either of two related but distinct trends in Post-war Modernist painting: European Abstraction Lyrique born in Paris, the French art critic Jean José Marchand being credited with coining its name in 1947, considered as a component of Tachisme when the name of this movement was coined in 1951 by Pierre Guéguen and Charles Estienne the author of L'Art à Paris 1945–1966, and American Lyrical Abstraction a movement described by Larry Aldrich (the founder of the Aldrich Contemporary Art Mu
PCI ExpressPCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe or PCI-e, is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X and AGP bus standards. It is the common motherboard interface for personal computers' graphics cards, sound cards, hard disk drive host adapters, SSDs, Wi-Fi and Ethernet hardware connections.
Abstraction (mathematics)Abstraction in mathematics is the process of extracting the underlying structures, patterns or properties of a mathematical concept, removing any dependence on real world objects with which it might originally have been connected, and generalizing it so that it has wider applications or matching among other abstract descriptions of equivalent phenomena. Two of the most highly abstract areas of modern mathematics are and model theory.
Abstract interpretationIn computer science, abstract interpretation is a theory of sound approximation of the semantics of computer programs, based on monotonic functions over ordered sets, especially lattices. It can be viewed as a partial execution of a computer program which gains information about its semantics (e.g., control-flow, data-flow) without performing all the calculations.
Object-based languageThe term object-based language may be used in a technical sense to describe any programming language that uses the idea of encapsulating state and operations inside objects. Object-based languages need not support inheritance or subtyping, but those that do are also termed object-oriented. Object-based languages that do not support inheritance or subtyping are usually not considered to be true object-oriented languages.
Abstract artAbstract art uses visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Western art had been, from the Renaissance up to the middle of the 19th century, underpinned by the logic of perspective and an attempt to reproduce an illusion of visible reality. By the end of the 19th century many artists felt a need to create a new kind of art which would encompass the fundamental changes taking place in technology, science and philosophy.
