Considering a system with five processes: P1, P2, P3, P4, and P5 and four resources: A, B, C, D. Resource type A has five instances, B has 11 instances, type C has five instances, and D has nine instances. Suppose at time , the following snapshot of the system has been taken:

a. Draw the resource allocation graph of the system at this current time t₀

Using the Bankers algorithm and answer the following questions:

b. What is the content of the matrix Need?

c. What is the safe sequence of resource allocation that keeps the system in a safe state?

d. If a request from process P2 arrives for (1,3,3,0), can the request be granted immediately? Explain your answer.

Allocation Max Available Process A B C D A B C D A B C D P1 1 3 0 2 2 6 0 2 3 2 4 2 P2 0 0 0 1 4 5 0 4 P3 0 1 0 0 1 1 1 2 P4 5 1 1 2 6 4 4 P5 0 0 0 3 1 4 5 5
