1) An application comprises several processes a primary process and some child processes. This arrangement provides computation speedup if a. The computer system contains many CPUs b. Some of the processes are I/O bound c. Some of the processes are CPU bound d. None of the above

2)Classify each of the following statements as true or false: a. The OS creates a single process if two users execute the same program. b. The state of a process that is blocked on a resource request changes to running when the resource is granted to it. c. There is no distinction between a terminated process and a suspended process. d. After handling an event, the kernel need not perform scheduling before dispatching if none of the process states has chang e. When a user-level thread of a process makes a system call that leads to blocking, all threads of the process become blocked. f. Kernel-level threads provide more concurrency than user-level threads in both uniprocessor and multiprocessor systems. g. When a process terminates, its termination code should be remembered until its parent process terminates

3) Which of the following state transitions for a process can cause the state transition blocked ready for one or more other processes? a. A process starts an I/O operation and becomes blocked. b. A process terminates. c. A process makes a resource request and becomes blocked. d. A process sends a message. e. A process makes the state transition blocked blocked swapped.
