"WebPreemptive Scheduling. Preemptive scheduling is a popular and elegant scheduling mechanism. A simple view of how it works is to picture a timer interrupt that happens at a fixed rate. Each time the interrupt happens the interrupt service routine (ISR) switches the stack to a stack for another task, and when it returns from the ISR it returns to ...
