1. Considering a system with five processes P0 through P4 and three resources types A,B, C. Resource type Ahas 2 instances, B has 7 instances and type C has 6 instances. Suppose at time t0 following snapshot of the system has been taken: By applying banker's algorithm i. What will be the content of need matrix? ii. Is the system in safe state? If yes, then what is the safe sequence? 2. Consider the following page reference string: 1,2,3,4,1,2,0,1,2,3,4,5,2,3,1,2,0,1,2,1 How many page faults would occur for the Optimal Replacement algorithm (ORA), assuming three frames? 3. Calculate average waiting time and draw Gantt chart for the following table using Round Robin Algorithm and time quantum =4ms
