Assume that at time 0 no system resources are being used except for the processor and memory. Now consider the following events:
At time 5: P1 executes a command to read from disk unit 3.
At time 10: P2’s time slice expires.
At time 15: P3 executes a command to write to disk unit 2.
At time 20: P1 is swapped out.
At time 25: An interrupt occurs from disk unit 2: P3’s write is complete
At time 30: P2 terminates.
At time 31 identify which state each process is in:
P1
P2
P3
