What is preemptive scheduling?
Preemptive scheduling is a method where the operating system can interrupt a currently running task to start or resume another task.
How does it differ from non-preemptive scheduling?
In non-preemptive scheduling, a running task cannot be interrupted; it runs to completion before the next task starts.
What are the advantages of preemptive scheduling?
It allows for better responsiveness and resource utilization, as high-priority tasks can be executed immediately.
Can you give an example of preemptive scheduling in action?
Sure! In a multi-tasking operating system, if a user opens a high-priority application, the OS can pause a lower-priority task to allocate resources to the high-priority one.
