i need answer in detail.

1. Consider the following partial timeline of process events Time Event Process P1 executes the command: Read from disk unit 3 15 P5's time slice expires 18 P7 executes the command: Write to disk unit 3 20 P3 executes the command: Read from disk unit 2 24 P5 executes the command: Write to disk unit 3 28 P5 is swapped out 33 Disk unit 2 generates an interrupt: Read is complete for P3 36 Disk unit 3 generates an interrupt: Read is complete for P1 38 P8 terminates 40 Disk unit 3 generates an interrupt: Write is complete for P5 44 P5 is swapped back in 48 Disk unit 3 generates an interrupt Write is complete for P7 Assuming that before time 5, no system resources are used except for memory and the processor, complete the following state table. (Note: Time 22 has been completed for you in order to provide an example of how to fill out the table entries.) Time P1 P3 P5 P7 P8 22 Blocked for Blocked Ready/running Blocked Ready/running for I/O for I/O 37 47
