3. You could implement an application as either a uni-threaded process or a multi-threaded process or as multiple processes. (a) (4 points) Discuss the pros and cons of each of the three approaches listed above (b) (3 points) In case you choose the multi-threaded process approach, how does it matter whether the threads are user-level threads or kernel-level threads? Discuss the pros/cons of both options. (c) (3 points) If you were using kernel level threads and your machine is a uniprocessor, is there any benefit in running the application as a multi-threaded process versus a uni-threaded process?
