Consider a system with 3 I/O devices

a. Printer (priority of 2)

b. Disk (priority of 4)

c. Communication line (priority of 5)

User program begins at t = 0

At t = 10, printer interrupt occurs. Printer interrupt takes 20 units of time to complete.

At t = 15, disk interrupt occurs. Disk interrupt takes 30 units of time to complete.

At t = 20 communication interrupt occurs. Communication Line interrupt takes 10 units of time to complete.

Draw a time sequence of multiple interrupts for the above mentioned scenario
