Web6 feb. 2012 · 1. OS sets an interrupt timer, and lets the program run. Once the timer expires, control flow jumps to code of the OS for context switch. On the context switch OS saves registers and supporting data of the current process and replaces it in CPU with data of the next process in queue. WebIn preemptive multitasking, the operating system kernel can also initiate a context switch to satisfy the scheduling policy's priority constraint, thus preempting the active task. In general, preemption means "prior seizure of". When the high-priority task at that instance seizes the currently running task, it is known as preemptive scheduling.
