1If you have problems with homework, your first stop should be your teacher/prof/TA, not SO. – Martin James May 28 '16 at 21:07

Suppose a process is in running state. Now it moves to waiting state for I/O. In that case, another ready process will be context switched and will be executed.

@Ibrahim : So, nonpreemptive just means that if a process is getting executed , then other process will have to wait whether they have a shorter job, high priority or anything. But suppose a process is running and it has to take some I/O. So, it will be shifted to device queue and in the meantime there is no process which is getting executed and hence we can take one ready queue and execute it. – Priyansh Goel May 28 '16 at 17:52

2@Ibrahim : I think it would be good enough to create a new post for this problem as it is not related to the one we have discussed – Priyansh Goel May 28 '16 at 18:20

@MartinJames : You are rude, I must say. And there is no point of downvoting an answer just because it answers a conceptual homework question. – Priyansh Goel May 28 '16 at 23:00

@PriyanshGoel would you consider the gross homework question dumps on this tag, conceptual or otherwise, as 'rude' too, or abuse of SO contributors, or disrespect of other students who actually do some work, or something else? – Martin James May 29 '16 at 07:55
