1. Assume that at time 3 no system resources are being used except for the processor and memory. Now consider the following events:

• At time 2: P0 is ready.
• At time 4: P0 is selected by CPU scheduler
• At time 8: P0 executes a command to read from disk 0.
• At time 16: An interrupt occurs from disk unit 0: P0's read is complete.

For each time 2, 4, 8 and 16, identify which state process is in. If a process is blocked, further identify the event on which is it blocked.
