Explanation:
Detailed explanation-1: -Non-maskable interrupts are typically used to respond to high-priority requests such as watchdog timer timeouts, power-down signals and traps. Hardware timers are often used to generate periodic interrupts.
Detailed explanation-2: -Interrupt is the mechanism by which modules like I/O or memory may interrupt the normal processing by CPU. It may be either clicking a mouse, dragging a cursor, printing a document etc the case where interrupt is getting generated. Why we require Interrupt?
