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%

Which of the following statements is false? a. a class can directly inherit from class object. b. if the class you're inheriting from declares instance variables as private, the inherited class can access those instance variables directly. c. a class's instance variables are normally declared private to enforce good software engineering. d. it's often much more efficient to create a class by inheriting from a similar class than to create the class by writing every line of code the new class requires.
