(In this case, an I/O queue is used, and processes are entered at the end of the I/O queue whenever they request I/O. Whenever the I/O device is available, the Nonpremptive FCFS I/O Scheduler always removes from the I/O queue the process which is at the front of the I/O queue, and allows that process to start performing I/O on the I/O device for the full duration of its I/O Time before that process makes the next request to execute on the CPU - after completing I/O the process will be entered into the ready queue.)
