  2. Model of computation - Wikipedia

    en.wikipedia.org/wiki/Model_of_computation

    In the field of runtime analysis of algorithms, it is common to specify a computational model in terms of primitive operations allowed which have unit cost, or simply unit-cost operations. A commonly used example is the random-access machine, which has unit cost for read and write access to all of its memory cells. In this respect, it differs ...

  3. Language primitive - Wikipedia

    en.wikipedia.org/wiki/Language_primitive

    In computing, language primitives are the simplest elements available in a programming language. A primitive is the smallest 'unit of processing' available to a programmer of a given machine, or can be an atomic element of an expression in a language. Primitives are units with a meaning, i.e., a semantic value in the language.

  4. Primitive - Wikipedia

    en.wikipedia.org/wiki/Primitive

    Cryptographic primitives, low-level cryptographic algorithms frequently used to build computer security systems; Geometric primitive, the simplest kinds of figures in computer graphics; Language primitive, the simplest element provided by a programming language; Primitive data type, a datatype provided by a programming language

  5. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    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.

  6. Constructive solid geometry - Wikipedia

    en.wikipedia.org/wiki/Constructive_solid_geometry

    The simplest solid objects used for the representation are called geometric primitives. Typically they are the objects of simple shape: cuboids, cylinders, prisms, pyramids, spheres, cones. [1] The set of allowable primitives is limited by each software package. Some software packages allow CSG on curved objects while other packages do not.

  7. Geometric primitive - Wikipedia

    en.wikipedia.org/wiki/Geometric_primitive

    In vector computer graphics, CAD systems, and geographic information systems, geometric primitive (or prim) is the simplest (i.e. 'atomic' or irreducible) geometric shape that the system can handle (draw, store).

  8. CAR and CDR - Wikipedia

    en.wikipedia.org/wiki/CAR_and_CDR

    In computer programming, CAR (car) / k ɑːr / ⓘ and CDR (cdr) (/ ˈ k ʌ d ər / ⓘ or / ˈ k ʊ d ər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...

  9. Primitive data type - Wikipedia

    en.wikipedia.org/wiki/Primitive_data_type

    In computer science, primitive data types are a set of basic data types from which all other data types are constructed. [1] Specifically it often refers to the limited set of data representations in use by a particular processor , which all compiled programs must use.
