Show answer & explanation
Correct answer: A
The correct answer is a vectored interrupt. In this mechanism, the external device supplies its own address along with the interrupt request signal. This allows the CPU to directly identify and access the specific Interrupt Service Routine (ISR) associated with that device, distinguishing it from non-vectored interrupts where the CPU must determine the address through polling or a fixed vector.
