|
Gives processor time to each process in turn
|
|
Allows processes to be prioritized
|
|
Always completes the shortest processes first and so is very responsive
|
|
Ensure that some processes become deadlocked
|
Detailed explanation-1: -It allows various processes to switch across queues. Prevents CPU overload. After a specific amount of time, a mechanism known as Aging helps move a lower priority activity to the next higher priority queue.
Detailed explanation-2: -It enables a process to switch between queues. If a process consumes too much processor time, it will be switched to the lowest priority queue. A process waiting in a lower priority queue for too long may be shifted to a higher priority queue. This type of aging prevents starvation.
Detailed explanation-3: -Advantages of Multilevel Feedback Queue Scheduling It helps in preventing starvation as a process of a low priority queue need not wait indefinitely and can be moved to a queue with higher priority.
Detailed explanation-4: -In computer science, a multilevel feedback queue is a scheduling algorithm. Scheduling algorithms are designed to have some process running at all times to keep the central processing unit (CPU) busy.
Detailed explanation-5: -This is a flexible Scheduling Algorithm. This scheduling algorithm allows different processes to move between different queues. In this algorithm, A process that waits too long in a lower priority queue may be moved to a higher priority queue which helps in preventing starvation.
