What Is Multilevel Feedback Scheduling?
Multilevel feedback scheduling is a dynamic scheduling algorithm used in operating systems to manage the execution of processes efficiently. In this system, the ready queue is divided into several separate queues, each with a distinct priority level. The priority levels are typically organized in a hierarchical manner, with the highest priority queue being the most critical.
Processes enter the highest priority queue when they are initially ready for execution. If a process doesn’t complete its execution or encounters an I/O operation, it is moved to a lower-priority queue. This mechanism allows the scheduler to give more CPU time to processes in higher-priority queues while ensuring that processes in lower-priority queues eventually get their turn. This approach not only ensures fair CPU time allocation but also enhances the system’s responsiveness, particularly for interactive processes that require quick user feedback.
Overall, multilevel feedback scheduling is a dynamic and adaptable scheduling strategy that helps maintain system efficiency and responsiveness by adjusting the priority of processes based on their behavior and requirements.
How Does Multilevel Queue Scheduling Algorithm Work?
The multilevel queue scheduling algorithm is a method used in operating systems to efficiently manage the execution of processes. This algorithm divides the ready queue into multiple distinct queues, with each queue serving as a designated group for processes based on specific attributes. Typically, processes are permanently categorized into these queues, and the categorization is determined by various factors, including memory requirements, priority levels, and the nature of the process itself.
Each individual queue within the multilevel structure operates independently, utilizing its unique scheduling algorithm. These algorithms are tailored to suit the characteristics and demands of the processes assigned to each queue. As a result, this approach enables the operating system to prioritize and manage processes more effectively, ensuring that processes with higher priority or specific requirements receive appropriate attention and resources. Overall, the multilevel queue scheduling algorithm enhances system efficiency by streamlining the way processes are selected for execution, promoting better resource utilization and overall system performance.
What Is A Multilevel Feedback?
A multilevel feedback queue scheduler is a dynamic scheduling algorithm used in computer operating systems to efficiently manage processes. This scheduling strategy is characterized by several key parameters that define its behavior:
-
Number of Queues: A crucial aspect of a multilevel feedback queue scheduler is the division of processes into multiple priority-based queues. These queues are organized in a hierarchical fashion, with each queue representing a different level of priority.
-
Scheduling Algorithm: One notable feature is the ability to apply distinct scheduling algorithms to each queue. This means that processes in different queues can be scheduled using various methods. For example, one queue may use a First-In-First-Out (FIFO) scheduling algorithm, while another might employ a Round Robin or Priority-based algorithm. This flexibility allows the scheduler to adapt to different workload characteristics and system requirements.
-
Promotion Mechanism: Another essential aspect is the method used to determine when a process should be promoted to a higher-priority queue. This mechanism typically relies on factors such as the amount of CPU time a process has consumed or the number of times it has been preempted. When a process meets the promotion criteria, it is moved to a higher-priority queue, allowing it to receive more CPU time and resources.
By incorporating these parameters, a multilevel feedback queue scheduler can effectively manage processes with varying priority levels and workload demands, ensuring efficient system resource utilization and responsiveness to changing system conditions.

In a multilevel queue-scheduling algorithm, processes are permanently assigned to a queue on entry to the system. Processes do not move between queues. This setup has the advantage of low scheduling overhead, but the disadvantage of being inflexible.Multilevel feedback scheduling divides the ready queue into multiple queues with different priorities. Processes move to lower priority queues if they don’t complete execution or perform I/O operations. This approach provides fair CPU time allocation and better responsiveness for interactive processes.A multi-level queue scheduling algorithm partitions the ready queue into several separate queues. The processes are permanently assigned to one queue, generally based on some property of the process, such as memory size, process priority, or process type. Each queue has its own scheduling algorithm.
