Please answer the following Operating Systems Quetion and its two parts: Part A: The four conditions (mutual exclusion, hold and wait, no preemption and circular wait) are necessary for a resource deadlock to occur. Give an example to show that these conditions are not sufficient for a resource deadlock to occur. When are these conditions sufficient for a resource deadlock to occur? Part B: A system has two processes and three identical resources. Each process needs a maximum of two resources. Is deadlock possible? Explain your answer.
