  2. Idle (CPU) - Wikipedia

    en.wikipedia.org/wiki/Idle_(CPU)

    Many operating systems, for example Windows, [1] Linux, [2] and macOS [3] will run an idle task, which is a special task loaded by the OS scheduler on a CPU when there is nothing for the CPU to do. The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority.

  3. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...

  4. System Idle Process - Wikipedia

    en.wikipedia.org/wiki/System_Idle_Process

    In Windows NT operating systems, the System Idle Process contains one or more kernel threads which run when no other runnable thread can be scheduled on a CPU. In a multiprocessor system, there is one idle thread associated with each CPU core. For a system with hyperthreading enabled, there is an idle thread for each logical processor.

  5. I/O bound - Wikipedia

    en.wikipedia.org/wiki/I/O_bound

    At this point, the CPU sits idle. The CPU-bound process will then move back to the ready queue and be allocated the CPU. Again, all the I/O processes end up waiting in the ready queue until the CPU-bound process is done. There is a convoy effect as all the other processes wait for the one big process to get off the CPU. This effect results in ...

    en.wikipedia.org/wiki/Central_processing_unit

    A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer. [1] [2] Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations.
