Operating SystemWhich of the following is an advantage of using threads? (i) Increased hardware costs (ii) Lower throughput (iii) Efficient utilization of CPU resources (iv) Increased memory consumption20242mOPERATING SYSTEMConsider a system running ten I/O-bound tasks and one CPU-bound task. Assume that the I/O-bound tasks issue an I/O operation once for every millisecond of CPU computing and that each I/O operation takes 10 milliseconds to complete. Also assume that the context-switching overhead is 0.1 millisecond and that all processes are long-running tasks. Describe the CPU utilization for round-robin scheduler when: (i) the time quantum is 1 millisecond; (ii) the time quantum is 10 milli-seconds.20227mOperating SystemWhich module gives control of the CPU to the process selected by the short-term scheduler?
