  2. Abstraction (computer science) - Wikipedia

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

    An example of this abstraction process is the generational development of programming language from the machine language to the assembly language and the high-level language. Each stage can be used as a stepping stone for the next stage. The language abstraction continues for example in scripting languages and domain-specific programming languages.

  3. Abstraction principle (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Abstraction_principle...

    The abstraction principle is mentioned in several books. Some of these, together with the formulation if it is succinct, are listed below. Alfred John Cole, Ronald Morrison (1982) An introduction to programming with S-algol: "[Abstraction] when applied to language design is to define all the semantically meaningful syntactic categories in the language and allow an abstraction over them".

  4. List of abstractions (computer science) - Wikipedia

    en.wikipedia.org/wiki/List_of_abstractions...

    Programming paradigms constitute the theoretical frameworks that shape the way software constructs are created and executed. Each paradigm embodies a unique approach to organizing and structuring programming logic, often promoting particular forms of abstraction and compositional structures that align with their underlying principles.

  5. High-level programming language - Wikipedia

    en.wikipedia.org/wiki/High-level_programming...

    In computer science, a high-level programming language is a programming language with strong abstraction from the details of the computer.In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program ...

  6. Hardware abstraction - Wikipedia

    en.wikipedia.org/wiki/Hardware_abstraction

    A hardware abstraction layer (HAL) is an abstraction layer, implemented in software, between the physical hardware of a computer and the software that runs on that computer. . Its function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardwa

  7. Abstraction layer - Wikipedia

    en.wikipedia.org/wiki/Abstraction_layer

    In 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.

  8. Bridge pattern - Wikipedia

    en.wikipedia.org/wiki/Bridge_pattern

    Separate an abstraction (Abstraction) from its implementation (Implementor) by putting them in separate class hierarchies. Implement the Abstraction in terms of (by delegating to) an Implementor object. This enables to configure an Abstraction with an Implementor object at run-time. See also the Unified Modeling Language class and sequence ...

  9. List (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/List_(abstract_data_type)

    For example, Lua provides tables. Although Lua stores lists that have numerical indices as arrays internally, they still appear as dictionaries. [4] In Lisp, lists are the fundamental data type and can represent both program code and data.
