17] Process creation, termination, cooperation, and inter-process communication are highly interrelated concepts in OSs. Briefly describe one application (hypothetical or real life type) where processes must be created, or spawned. and managed to allow speed up in computations that involve all of these process concepts listed above. [Don't simply define or describe these concepts; the emphasis is on the (12pts) [8] Consider the following set of processes with the given CPU burst times, and priority levels (3 is lowest and 1 is highest).
