When the process issues an I/O request __________

It is placed in an I/O queue

It is placed in a waiting queue

It is placed in the ready queue

It is placed in the Job queue

When the process issues an I/O request it is placed in an I/O queue. I/O is a resource and it should be used effectively and every process should get access to it. There might be multiple processes which requested for I/O. Depending on scheduling algorithm I/O is allocated to any particular process and after completing I/O operation, I/O access is returned to the OS.
