Process States

1-Given the ice cream example from the beginning of this chapter, identify the four necessary conditions for deadlock and explain whether each one is present, or is not present, in this case.

2. Consider a single lane street that is undergoing construction. How can the construction manager monitor the traffic so all traffic can move in each direction. Create a list of actions or tasks that could be implemented by the construction manager. That would allow all cars t to use the street without risking a deadlock or starvation.

6. Consider a system with 13 dedicated devices of the same type and all jobs currently running on this system require a maximum of 3 devices to complete their execution but they each run for long periods of time with just 2 devices and request the remaining one only at the very end of the run. Assume that the job stream is endless and that your operating systems device allocation policy is a very conservative one: No job will be started unless all the required drives have been allocated to it for the entire duration of its run.

a. What is the maximum number of jobs that can be in progress at once? Explain your answer.

b. What are the minimum and maximum number of devices that may be idle because of this policy? Under what circumstances would an additional job be started?
