Answer the Following Questions– whole assignment should be equal to two pages in length.
4. Assume that your system has one queue for jobs waiting for printing, and another queue for those waiting for access to a disk. Which queue would you expect to have the faster response? Explain your reasoning?
13. Some guidelines for selecting the right time quantum were given in this chapter. As a system designer, which guidelines do you prefer? Which would the aver- age user prefer? How would you know when you have chosen the best time quantum? What factors would make this time quantum best from the system’s point of view?
15. When using a personal computer, it can be easy to determine when a job is caught in an infinite loop or system-wide freeze. The typical solution to this problem is for the user to manually intervene and terminate the offending job or, in the worst case, all jobs. What mechanism would you implement in the Process Scheduler to automate the termination of a job that’s in an infinite loop? Take into account jobs that legitimately use large amounts of CPU time.
3. Regarding the role played by the victim in deadlock resolution, give an example of such a deadlock in real life and explain your answers to these questions. a. Describe how you might choose the victim to be removed, and the consequences, both positive and negative, of that removal. b. Describe the fate of the victim and the chances of eventually completing its processing. c. Describe the actions required, if any, to complete the victim’s tasks.
14. For each of these conditions—deadlock, livelock, race, and starvation—give at least one real-life example, which is not related to a computer system environment and not already suggested in this chapter, of each of these concepts. Then give your own opinion on how each of the four examples can be resolved.
