[BahremandQ4] Explain why the queue diagram in slide 9 has a continuous cycle that flows between the listed queues and resources? Is a cycle necessary?

SCHEDULING QUEUES ready queue CPU - Given that we want to support I/O queue l/O /O request executing more than one process at a time, OSs need some sort of process scheduler that divides up resources (CPU time) time slice expired fork a child executes - We have two general notations: interrupt occurs wait for an interrupt Ready queue: processes ready to execute on the CPU. Queueing Diagram- rectangles indicates Device queue: processes waiting queues, ovals indicate resources. to use a device/resource. - Whenever a process from the ready queue is we say that it is dispatched Would it make sense to use priority queues? given CPU time, Image from Operating System Concepts
