  1.

Such changes of the executed task are known as context switches.

    What is a preemptive scheduler?
    This interrupt is done by an external scheduler with no assistance or cooperation from the task. : 153 This preemptive scheduler usually runs in the most privileged protection ring, meaning that interruption and resuming are considered highly secure actions.

    What is a preemptive multitasking operating system?
    The term preemptive multitasking is used to distinguish a multitasking operating system, which permits preemption of tasks, from a cooperative multitasking system wherein processes or tasks must be explicitly programmed to yield when they do not need system resources.

    Why are some operations not preemptable?
    In any given system design, some operations performed by the system may not be preemptable. This usually applies to kernel functions and service interrupts which, if not permitted to run to completion, would tend to produce race conditions resulting in deadlock.
