Explain why interrupts are not appropriate for implementing synchronization primitives in multiprocessor systems.

Distinguishing between interrupt-driven I/O and programmable I/O, what is the primary distinction?

When comparing programmable I/O versus interrupt-driven I/O, what are the key differences?

The CPU will quickly pause whatever task it is working on and attend to the problem in the event that an interrupt occurs. In the language of technology, this is referred as as an interrupt service. What may possibly be the cause of the current process coming to a halt? You may want to think about completing the task at hand now and dealing with the interruption later.
