  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. Outline of computer programming - Wikipedia

    en.wikipedia.org/.../Outline_of_computer_programming

    Programming involves activities such as analysis, developing understanding, generating algorithms, verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding [1] [2]) of algorithms in a target programming language.

  4. Execution (computing) - Wikipedia

    en.wikipedia.org/wiki/Execution_(computing)

    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.

  5. Program lifecycle phase - Wikipedia

    en.wikipedia.org/wiki/Program_lifecycle_phase

    Program lifecycle phases are the stages a computer program undergoes, from initial creation to deployment and execution. The phases are edit time, compile time, link time, distribution time, installation time, load time, and run time. Lifecycle phases do not necessarily happen in a linear order, and they can be intertwined in various ways.

  6. Computer program - Wikipedia

    en.wikipedia.org/wiki/Computer_program

    Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. An operating system is the low-level software that supports a computer's basic functions, such as scheduling processes and controlling peripherals. [122] In the 1950s, the programmer, who was also the operator, would write a program and run it.

  7. Computer programming - Wikipedia

    en.wikipedia.org/wiki/Computer_programming

    Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.

  8. Software development process - Wikipedia

    en.wikipedia.org/wiki/Software_development_process

    In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .

  9. Cycles per instruction - Wikipedia

    en.wikipedia.org/wiki/Cycles_per_instruction

    Each stage requires one clock cycle and an instruction passes through the stages sequentially. Without pipelining , in a multi-cycle processor , a new instruction is fetched in stage 1 only after the previous instruction finishes at stage 5, therefore the number of clock cycles it takes to execute an instruction is five (CPI = 5 > 1).
