  2. Post–Turing machine - Wikipedia

    en.wikipedia.org/wiki/Post–Turing_machine

    A Post–Turing machine [1] is a "program formulation" of a type of Turing machine, comprising a variant of Emil Post's Turing-equivalent model of computation.Post's model and Turing's model, though very similar to one another, were developed independently.

  3. Computer science - Wikipedia

    en.wikipedia.org/wiki/Computer_science

    Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).

  4. Postcondition - Wikipedia

    en.wikipedia.org/wiki/Postcondition

    In computer programming, a postcondition is a condition or predicate that must always be true just after the execution of some section of code or after an operation in a formal specification. Postconditions are sometimes tested using assertions within the code itself. Often, postconditions are simply included in the documentation of the ...

    The correct number of sections for a fence is n − 1 if the fence is a free-standing line segment bounded by a post at each of its ends (e.g., a fence between two passageway gaps), n if the fence forms one complete, free-standing loop (e.g., enclosure accessible by surmounting, such as a boxing ring), or n + 1 if posts do not occur at the ends ...

  6. Outline of computer science - Wikipedia

    en.wikipedia.org/wiki/Outline_of_computer_science

    Computer science (also called computing science) is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. One well known subject classification system for computer science is the ACM Computing Classification System devised by the Association for Computing Machinery .

  7. Power-on self-test - Wikipedia

    en.wikipedia.org/wiki/Power-on_self-test

    A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.

  9. Computation - Wikipedia

    en.wikipedia.org/wiki/Computation

    Computation can be seen as a purely physical process occurring inside a closed physical system called a computer. Turing's 1937 proof, On Computable Numbers, with an Application to the Entscheidungsproblem , demonstrated that there is a formal equivalence between computable statements and particular physical systems, commonly called computers .
