Consider a system using RR scheduling with a fixed quantum q. Every context switch takes s ms. Any given thread runs for an average of t ms before it blocks or terminates. (a) Determine the fraction of the CPU time that will be wasted because of context switching for each of the following cases:.
i. t < q
ii. t >> q (i. e, t is much greater than q)
iii. q approaches 0.
(b) Under what condition will the wasted fraction of CPU time be exactly 50%
