The diagram given below represents
Diagram: Processes enter a 'ready queue' which feeds the 'CPU'; an arrow leaves the CPU (exit). From the CPU, four paths lead back to the ready queue:
1. I/O request → I/O queue → I/O → back to ready queue
2. time slice expired → back to ready queue
3. fork a child → child executes → back to ready queue
4. wait for an interrupt → interrupt occurs → back to ready queue
