1. Why is Prevention not a practical solution to deadlocks? 2. Draw two Resource Allocation Graphs. One depicting three process in deadlock. One depicting at least four processes with no deadlock. 3. 200 memory units are available to the Operating System. Process A is using 50 units and can claim 100. Process B is using 10 units and can claim 30 units. Process C is using 20 units and can claim 60. Process D is using 40 units and can claim 80. Process A requests an additional 30 units. Can the OS grant the request? Show you work. 4. (What is the most common method of handling deadlocks in modern operating systems? 5.
