In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor. [ 1 ] A given ISA may be implemented with different microarchitectures; [ 2 ][ 3 ...
von Neumann architecture. The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1 ] The document describes a design architecture for an electronic digital computer ...
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system. A system architecture can consist of system ...
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. [ 1 ] From a sociotechnical perspective, information systems comprise four components: task, people, structure (or roles), and technology. [ 2 ] Information systems can be defined as an integration of ...
The Open Systems Interconnection (OSI) model is a reference model from the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." [2] In the OSI reference model, the communications between systems are split into seven different ...
Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [ 1 ] and extended in 1972. [ 2 ] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities. Since the rise of multiprocessing central processing units (CPUs), a ...
Computer science is the study of computation, information, and automation. [1][2][3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software). [4][5][6] Algorithms and data structures are central to ...
