2. Considering a system with three (3) processes P1 through P3 and three resources types A, B, C. Resource type A has 13 instances, B has 11 instances and type C has 10 instances. Suppose at time to, the following snapshot of the system has been taken: Process Allocation B 2 2 3 Max A B 6 4 Available B 2 2. 2 P1 4 P2 5 4 2 7 4 2 P3 4 3 3 5 4 4 4 Analyze the above table and answer the following questions: a. Calculate the NEED matrix (2.25 Marks) Process Need B P1 P2 P3 b. Use Banker's Algorithm to test if the system is in safe state. If the system is in safe state, write the safe sequence. (6.75 marks)
