  • The hardware interrupts which can be delayed when a much high priority interrupt has occurred at the same time is called a maskable interrupt.
  • Unplanned interrupts while executing a program are called Exception.
  • The Source of interrupt is in phase with the clock is called a synchronous interrupt.
