Multi-level Queue Scheduling

Multi-level Queue Scheduling is a method used by operating systems to organize and manage multiple tasks or processes. It divides tasks into different categories or queues based on their priority or type, such as real-time, user programs, or background processes. Each queue has its own scheduling rules, and tasks are assigned to queues accordingly. The system then manages these queues separately, ensuring that high-priority tasks are attended to quickly while lower-priority ones are processed when possible. This approach helps efficiently allocate resources and improve overall system responsiveness by respecting the different needs of various tasks.
