Question-03: In a deadlock scenario, a safe state is one in which there is at least one sequence of resource allocations to processes that does not result in a deadlock (i.e., all of the processes can be run to completion). An unsafe state is of course, a state that is not safe. Consider the following snapshot of a system, where there are no outstanding unsatisfied requests for resources. (04 + 04 = 08 Marks) Page 1 of 2 Ri 2 Available Resources R R3 1 0 R4 0 Process Still Needs Current Allocation R2 R3 0 1 Ri R?

(b) Is this system currently in a safe or unsafe state? Why
