Q1. Assume you have a system with three processes (X, Y, and Z) and a single CPU. Process X has the highest priority, process Z has the lowest, and Y is in the middle. Assume a priority-based scheduler (i.e.. the scheduler runs the highest priority job, performing preemption as necessary). Processes can be in one of five states: RUNNING, READY, BLOCKED, NOT YET CREATED, or TERMINATED. Given the following cumulative timeline of process behavior, indicate the state the specified process is in AFTER that step, and all preceding steps, have taken place. For all questions in this Part, use the following options for each answer: 1. Running 2. Ready 3. Blocked 4. Process Has Not Created Yet 5. Terminated Step 1: Process X is loaded into memory and begins; it is the only user-level process in the system. i) Process X is in which state? ii) Process Y is in which state? Step 2: The running process issues an I/O request to the disk. iii) Process X is in which state? iv) Process Y is in which state? Step 3: The previously issued I/O request completes. v) Process X is in which state? vi) Process Y is in which state? vii) Process Z is in which state? Step 4: The running process completes. vii) Process X is in which state? ix) Process Y is in which state? x) Process Z is in which state? (10 Marks) Q1.
