  2. Instruction cycle - Wikipedia

    en.wikipedia.org/wiki/Instruction_cycle

    The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch–execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the execute stage.

  3. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    The DFD notation draws on graph theory, originally used in operational research to model workflow in organizations, and in computer science to model the flow of inputs and outputs across computations. [2] [3] DFD originated from the structured analysis and design technique methodology in the middle of the 1970s. [3]

  4. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.

  5. Raptor (programming language) - Wikipedia

    en.wikipedia.org/wiki/Raptor_(programming_language)

    RAPTOR allows users to write and execute programs using flowcharts. The simple language and graphical components of RAPTOR are designed to teach the major ideas of computer programming to students. It is typically used in academics to teach introductory programming concepts as well. [3]

  6. Control-flow graph - Wikipedia

    en.wikipedia.org/wiki/Control-flow_graph

    In computer science, a control-flow graph (CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution. The control-flow graph was discovered by Frances E. Allen , [ 1 ] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before.

  7. P versus NP problem - Wikipedia

    en.wikipedia.org/wiki/P_versus_NP_problem

    The class of questions where an answer can be verified in polynomial time is "NP", standing for "nondeterministic polynomial time". [Note 1] An answer to the P versus NP question would determine whether problems that can be verified in polynomial time can also be solved in polynomial time.

  8. Algorithm - Wikipedia

    en.wikipedia.org/wiki/Algorithm

    Flowchart of using successive subtractions to find the greatest common divisor of number r and s. In mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ⓘ) is a finite sequence of mathematically rigorous instructions, typically used to solve a class of specific problems or to perform a computation. [1]

  9. Flow diagram - Wikipedia

    en.wikipedia.org/wiki/Flow_diagram

    The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process. For example the Information Graphics: A Comprehensive Illustrated Reference by Harris (1999) gives two separate definitions:
