Quizplus · Accepted Answer

Preemptive multitasking is when the operating system controls when an application can use the CPU. The OS can interrupt an application if it is taking too long or if a higher priority application needs to run. This allows for better use of system resources and prevents one application from monopolizing the CPU.
