Response Details:
Dear Faree;
 
 

                  The basic idea is that a processor can mask or block interrupt requests to have the processor perform a task. A processor will typically not do this unless it gets really bogged down or busy. A non-maskable interrupt is used for very high priority tasks that you don't want the processor to be able to mask when it gets bogged down. So simply, an interrupt that can be turned off by the programmer is known as Maskable interrupt and an interrupt which can be never be turned off (ie.disabled) is known as Non-Maskable interrupt.

 
Hope that will help you perfectlt. :)
