  2. NACK-Oriented Reliable Multicast - Wikipedia

    en.wikipedia.org/wiki/NACK-Oriented_Reliable...

    A NORM node refers to an individual node taking part in a NORM session. Each node has a unique identifier. When a node transmits a NORM message, this identifier is noted as the source_id. A NORM instance refers to an individual node in the context of a continuous segment of a NORM session. When a node joins a NORM session, it has a unique node ...

  3. Multitier architecture - Wikipedia

    en.wikipedia.org/wiki/Multitier_architecture

    Overview of a three-tier application. Three-tier architecture is a client-server software architecture pattern in which the user interface (presentation), functional process logic ("business rules"), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms. [14]

  4. Normalization (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(machine...

    Layer normalization (LayerNorm) [13] is a popular alternative to BatchNorm. Unlike BatchNorm, which normalizes activations across the batch dimension for a given feature, LayerNorm normalizes across all the features within a single data sample. Compared to BatchNorm, LayerNorm's performance is not affected by batch size.

  5. Separation of concerns - Wikipedia

    en.wikipedia.org/wiki/Separation_of_concerns

    The mechanisms for modular or object-oriented programming that are provided by a programming language are mechanisms that allow developers to provide SoC. [4] For example, object-oriented programming languages such as C#, C++, Delphi, and Java can separate concerns into objects, and architectural design patterns like MVC or MVP can separate presentation and the data-processing (model) from ...

  6. Software architecture - Wikipedia

    en.wikipedia.org/wiki/Software_architecture

    Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.

  7. Instance (computer science) - Wikipedia

    en.wikipedia.org/wiki/Instance_(computer_science)

    In computer science, an instance is an occurrence of a software element that is based on a type definition. When created, an occurrence is said to have been instantiated , and both the creation process and the result of creation are called instantiation .

  8. Functional specification - Wikipedia

    en.wikipedia.org/wiki/Functional_specification

    A functional specification (also, functional spec, specs, functional specifications document (FSD), functional requirements specification) in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010).

  9. Metamodeling - Wikipedia

    en.wikipedia.org/wiki/Metamodeling

    In software engineering, the use of models is an alternative to more common code-based development techniques. A model always conforms to a unique metamodel. One of the currently most active branches of Model Driven Engineering is the approach named model-driven architecture proposed by OMG.
