Assume we are using a single-processor system, which means each time there is only one process running on CPU. At time 5 no system resources are being used except for the processor and memory and all processes (P1, P3, P5, P7, P8) are either in ready queue or on CPU. Now consider the following events: ( Hints: if a process executes something, it is on CPU at the point; if a process is going to do IO or creates a process, it needs to leave CPU immediately; Dont forget the property of a queue: first in, first out)

At time 5: P1 executes a command to read from disk unit 3.

At time 15: P5's time slice expires.

At time 18: P7 executes a command to write to disk unit 3.

At time 20: P3 executes a command to read from disk unit 2.

At time 24: P5 executes a command to write to disk unit 3.

At time 28: P5 is swapped out.

At time 33: An interrupt occurs from disk unit 2: P3's read is complete.

At time 36: An interrupt occurs from disk unit 3: P1's read is complete.

At time 38: P8 terminates.

At time 40: An interrupt occurs from disk unit 3: P5's write is complete.

At time 44: P5 is swapped back in.

At time 48: An interrupt occurs from disk unit 3: P7's write is complete.

What you need to do:

For each time 22, 37, and 47, identify which state each process is in. If a process is blocked or blocked suspend, further identify the event on which is it blocked.

Your answer:

The two processes states at time 22 are given for your reference.

At time 22:

P1: blocked (Read from disk3).

P3:

P5: running

P7:

P8:

Can u please explain ur awnser thank you
