Pre-emptive multitasking is a form of Computer multitasking. To understand the concept, compare to ''cooperative multiprocessing'', in which only the active task (a.k.a. process) may initiate a context switch: * Because the task has completed processing. * Because the task has become blocked on a shared resource. * Because the task is yielding the processor to another, similarly co-operative multitasking, task. In pre-emptive multitasking, the Operating System kernel can also initiate a context switch to satisfy the scheduling policy's priority constraint, thus pre-empting the active task. Usage: ''Pre-emptive multitasking'' is sometimes mistakenly used when the intended meaning is more specific, referring instead to the class of scheduling policies known as ''time-shared scheduling'', or ''time-sharing''. == See also == *Scheduling *Scheduling policy *Time-sharing *Co-operative multitasking Operating system technology
