  2. 4+1 architectural view model - Wikipedia

    en.wikipedia.org/wiki/4+1_architectural_view_model

    The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.

  3. Von Neumann architecture - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann_architecture

    A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.

    Hack Computer CPU Block Diagram. As illustrated in the accompanying diagram, the Hack computer central processing unit (CPU) is an integrated logic unit with internal structure. It provides many of the functions found in simple, commercially available CPUs.

  5. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]

  6. High-level design - Wikipedia

    en.wikipedia.org/wiki/High-level_design

    High-level design (HLD) explains the architecture that would be used to develop a system.The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces.

    To produce the logical specification, the analyst builds the required logical models for both the data-flow diagrams (DFDs) and the Logical Data Model (LDM), consisting of the Logical Data Structure (referred to in other methods as entity relationship diagrams) and full descriptions of the data and its relationships. These are used to produce ...

  8. Diagrammatic reasoning - Wikipedia

    en.wikipedia.org/wiki/Diagrammatic_reasoning

    A logical graph is a special type of graph-theoretic structure in any one of several systems of graphical syntax that Charles Sanders Peirce developed for logic.. In his papers on qualitative logic, entitative graphs, and existential graphs, Peirce developed several versions of a graphical formalism, or a graph-theoretic formal language, designed to be interpreted for logic.

    Use case diagrams are used to identify the actor (users or other systems) and the processes they perform. System sequence diagram: A system sequence diagram (SSD) is a picture that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.
