In Multilevel Feedback queue (MLFQ) it allows a process to move betweenthe queues, according to the characteristics of their CPU burst. 3. InMultilevel queue (MLQ) the foregroundqueue might be scheduled by Round Robin algorithm while the back groundqueue is scheduled by First Come First Serve algorithm.

Answer 2

Multilevel Queue Scheduling vs Multilevel Feedback Queue Scheduling

Multilevel Queue Scheduling:

• The ready queue is divided into smaller queues and are arranged on the basis of priority of the process.
• Each smaller queue has its own scheduling algorithm.
• The processes are permanently stored n 1 queue.
• Processes do not move in the queue.
• Separate queues for background and foreground processes.

Multilevel Feedback Queue Scheduling:

• Allows processes to move between the queues.
• Priorities are shifted according to the need.
• No such permanent queue bounding.
• Prevents starvation.
