One of the following cannot be classified as an Interrupt :

  • A.Priority
  • B.Daisy chaining
  • C.Non-maskable
  • D.Memory

Answer: D

The one that is not a class of interrupt is Memory.

Interrupts are described as priority interrupts (serviced according to a priority scheme), daisy-chained interrupts (devices connected in series so that priority follows position in the chain) and non-maskable interrupts (which cannot be disabled by the processor, such as power failure).

Memory is a hardware component, not a kind of interrupt, even though a memory error can raise one.
