Assume the system consists of four resources, R1, R2, R3, R4. Before any process runs, there are 5 R1s, 4 R2s, 7 R3s and 6 R4s available. There are also four processes, P1, P2, P3, P4. At the time of interest, the state of the program looks like this: Worst Case Need Current allocation Process R1 R2 R3 R4 R1 R2 R3 R4 P1 3 4 6 4 2 1 4 3 P2 1 3 3 3 0 2 1 1 P3 2 1 2 0 1 1 1 0 P4 1 4 1 0 1 0 0 0 a) Show that the system is safe in this state. b) What possible requests can be granted without driving the system into an unsafe state?
