Question

Consider a system with 3 I/O devices

•Printer (priority of 2)

•Disk (priority of 4)

•Communication line (priority of 5)

User program begins at t = 0 and the multiple interrupts occur at following time instances

•At t = 10, disk interrupt occurs

•At t = 15, printer interrupts occurs

•At t = 20 communication interrupt occurs

Show the time sequence of multiple interrupts, assuming that service routine for each interrupt takes 10 time units.
