Give an example of resource allocation graph & deadlocked, Computer Engineering

Assignment Help:

Suppose there are 2 copies of resource A, 3 copies of resource B, and 3 copies of resource C. Suppose further that process 1 holds one unit of resources B and C and is waiting for a unit of A; that process 2 is holding a unit of A and waiting on a unit of B; and that process 3 is holding one unit of A, two units of B, and one unit of C. Draw the resource allocation graph. Is the system in a deadlocked state? Why or why not?

Resource allocation graph is specified below:

Here is a cycle into the resource allocation graph shows system is not in a safe condition. System is in deadlock as needed resources are 1 unit of resource A and 1 unit of resource B whereas available resource is 1 unit of resource C. Not any of the process can be finished.
