(within the context of user = processes.. as a separate process?) o How are new processes created? Who can create them? o What are the most important scheduling criteria for this OS? o How does the short-term scheduler select the next process to = place in the CPU? What's the selection function? What's the decision = mode? o Is there a single ready queue or multiple ready queues? Any help would be greatly appreciated, thanks -Alan Tek
