Problem: A single process, with execution time of BT time units, is detected by the system that uses Round Robin algorithm with time quantum of QT time units. Every time the time quantum elapses; a context switch is always performed with CS time units. Assume that the process come at time equal to zero (0). 1) If BT is 25, QT is 10 and CS is 2, what is the CPU utilization of the system? a. Below 70% b. 70-79% c. 90- 100% d. 80-89% 2) If BT is 20, QT is 6 and CS is 1, what is the CPU utilization of the system? a. 95- 100% b. 90- 94% c. Below 85% d. 85-89% 3) What is the CPU utilization if BT is equal QT and QT is equal to CS? a. 100% b. 50% c. 75% d. 60%
