2. Give an original “real life” example (not related to a computer system environment, not discussed in our textbook or in lecture) of each of these concepts: deadlock, starvation, and race.

5. Using the narrow staircase example from the beginning of this chapter, create a list of features or actions that would allow people to use it without causing deadlock or starvation. 

14. As discussed in this chapter, a system that is in an unsafe state is not necessarily deadlocked. Explain why this is true. Give an example of such a system (in an unsafe state) and describe how all the processes could be completed without causing deadlock to occur.

16. Given the four primary types of resources—CPU, memory, secondary storage, and files—select for each one the most suitable technique described in this chapter to fight deadlock and briefly explain why you choose it.

1. Compare the processors’ access to main memory for the loosely coupled configuration and the symmetric multiprocessing configurations. Give a real-life example (not from lecture or textbook!) where the symmetric configuration might be preferred.

3. Describe the programmer’s role when implementing explicit parallelism.

6. Give a real-life example (not from lecture or textbook!) of busy-waiting.

8. Compare and contrast multiprocessing and concurrent processing.  Describe the role of process synchronization for both systems.

9. Describe the purpose of a buffer and give an example from your own experience (not from lecture or textbook!) where its use clearly benefits system response.
