What is preemptive scheduling in operating systems?
Preemptive scheduling is a method where the operating system can interrupt a currently running task to start or resume another task.
Can you give me an example of how preemptive scheduling works?
Sure! In a multi-tasking environment, if a high-priority task arrives while a low-priority task is running, the OS can preempt the low-priority task.
What are the advantages of preemptive scheduling?
The main advantages include improved responsiveness and better CPU utilization, as high-priority tasks can be executed promptly.
Are there any disadvantages to preemptive scheduling?
Yes, it can lead to issues like increased context switching overhead and potential starvation of lower-priority tasks.
