  2. Pointer (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Pointer_(computer_programming)

    In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need should not be the case. In computer science, a pointer is an object in many programming languages that stores a memory address.

  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. 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]

  5. 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 ...

  6. Microcode - Wikipedia

    en.wikipedia.org/wiki/Microcode

    A processor's microprograms operate on a more primitive, totally different, and much more hardware-oriented architecture than the assembly instructions visible to normal programmers. In coordination with the hardware, the microcode implements the programmer-visible architecture.

  7. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

  8. 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.

  9. Distributed shared memory - Wikipedia

    en.wikipedia.org/wiki/Distributed_shared_memory

    In computer science, distributed shared memory (DSM) is a form of memory architecture where physically separated memories can be addressed as a single shared address space. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two processors refers to ...
