(a) Modern operating systems are interrupt driven. If there are no processes to execute, no I/O devices to service, and no users to whom to respond, an operating system will sit quietly, waiting for an interrupt or a trap.

(b) What is the role of interrupt service routines and how are they related to the interrupt vector?
(c) Figure shows an interrupt time line for a single process doing output. Explain how this operation is being performed.
(d) The figure (a) and figure (b) show two different ways to deal with I/O (Input or Output) requests.
