Question
How does the Multi-level Feedback Queue scheduler ensure that interactive jobs are running quickly? (You should think about how MLFQ distinguishes between interactive and non-interactive jobs to answer this one.)
Expert Solution
Step 1
INTRODUCTION:
- This scheduling is similar to Multilevel Queue(MLQ) scheduling, except that you can move between queues in this procedure.
- MLFQ (Multilevel Feedback Queue Scheduling) continuously analyses the behavior or time of execution of processes and adjusts its priority accordingly.
- Take a look at the graphic and explanation below to make sure you understand everything.
- Due to certain brief processes consuming all of the CPU time, a process in the lower priority queue may suffer from hunger.
- An easy option is to raise the priority of all processes at regular intervals and move them all to the front of the priority queue.
- It's more adaptable.
