What is a multilevel scheduling?

Multilevel scheduling is a CPU scheduling algorithm that organizes processes into multiple priority levels or queues, allowing for different scheduling strategies at each level. Each queue can have its own scheduling algorithm, such as first-come, first-served or round-robin, enabling the system to optimize performance for various types of workloads. Processes are typically promoted or demoted between levels based on their behavior and resource needs. This approach enhances responsiveness and efficiency by balancing the needs of both high-priority and low-priority tasks.
