9- Assume that printer interrupt priority: 2, disk interrupt priority:4, serial line interrupt priority: 6, Ethernet interrupt priority: 5. Determine the order of interrupt services according to: A user program begins at t = 0. At t = 10, a printer interrupt occurs, takes 25s to complete it's ISR (Interrupt Service Routine) At t = 15, a disk interrupt occurs, takes 15s to complete it's ISR At t = 20, ethernet interrupt occurs, takes 10s to complete it's ISR At t = 25, a serial line interrupt occurs, takes 5s to complete it's ISR Find "t"value when the control returns to user program. 9- Assume that printer interrupt priority: 2, disk interrupt priority:4, serial line interrupt priority: 6, Ethernet interrupt priority: 5.
