Question

Consider a system with three I/O devices: a printer, a disk, and a communications line, with increasing priorities of 2, 4, and 5, respectively.. A user program begins at t = 0. At t = 5, a printer interrupt occurs;  at t = 15, a communications interrupt occurs. While this routine is executing, a disk interrupt occurs (t = 20).

Printer Interrupt service takes 10 time slots.

Communication Interrupt Service takes 10 time slots.

Disk Interrupt Service takes 8 time slots.

 

When will the control return to the user program? Show the changes in the following diagram
