  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. Central processing unit - Wikipedia

    en.wikipedia.org/wiki/Central_processing_unit

    A complete machine language instruction consists of an opcode and, in many cases, additional bits that specify arguments for the operation (for example, the numbers to be summed in the case of an addition operation). Going up the complexity scale, a machine language program is a collection of machine language instructions that the CPU executes.

  9. Process (computing) - Wikipedia

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

    While a computer program is a passive collection of instructions typically stored in a file on disk, a process is the execution of those instructions after being loaded from the disk into memory. Several processes may be associated with the same program; for example, opening up several instances of the same program often results in more than ...
