Execution without entering a deadlock state, Operating System

Assignment Help:

Q. Presume that a system is in an unsafe state. Illustrate that it is possible for the processes to complete their execution without entering a deadlock state.

Answer: An unsafe state mayn't necessarily lead to deadlock it just means that we cannot guarantee that deadlock will not take place. Therefore it is possible that a system in an unsafe state may still permit all processes to complete without deadlock occurring. Consider the circumstances where a system has 12 resources allocated among processes P0, P1, and P2. The resources are owed according to the following policy.
