Show answer & explanation
Correct answer: D
Correct matching:
(a) interrupts which can be delayed when a much higher priority interrupt has occurred → Maskable.
(b) Unplanned interrupts which occur while executing a program → Exception.
(c) Source of interrupt is in phase with the system clock → Synchronous.
Short explanations:
Maskable: These interrupts can be disabled or postponed (masked) so they can be delayed when a higher-priority interrupt occurs.
Exception: These are unplanned events or faults that occur during program execution (for example, divide-by-zero), and are reported as exceptions.
Synchronous: These interrupts are synchronized with the system clock or instruction stream, occurring in phase with the processor's operation.
