1. In executing Jobs A and B using the priority scheduling algorithm, what will happen if both jobs have: unequal priorities but equal CPU cycles? equal priorities but different CPU cycles?
2. Some operating systems add the command interpreter to the kernel. What will be the justification for this design principle?
3. How does the distinction between kernel mode and user mode function as a rudimentary form of protection (or security) system?
4. One major advantage of Multiprocessor systems is increased flexibility. Briefly explain how this very advantage introduces increased complexity in the system design.
5. what is process synchronization? List the different levels of parallelism that can occur and the level of synchronization that is required at each level, with justification(s).
6. Why is symmetric multiprocessing considered better than asymmetric multiprocessing, despite its simplicity in implementation?
7. Several locking mechanisms have been implemented to achieve process synchronization. Explain any two of them.
