3. Consider the following snapshot of a system Allocation ABCD 0 0 1 2 0 0 Max ABCD Available ABCD PO Pl P2 P3 P4 2 1 5 20 1 3 5 4 2 3 5 6 0 6 3 2 0 6 5 2 0 0 1 40 6 5 6 Answer the following questions using the banker's algorithm a) How many instances of each resource type does the system have? (5 points) b) What is the content of the matrix Need? Draw the table (5 points) c) Is the system in a safe state? Why? (10 points) d) If a request from process P1 arrives for (0, 4, 2, 0), can the request be granted immediately? Explain why. (Hint: Suppose the request is granted, then is the system safe? If yes, then the request can be granted immediately; else, it cannot be granted. So, for this question, you need to inspect whether the system is safe after the request is granted.) (10 points)
