UGC-NET | UGC NET CS 2017 Jan – III | Question 1

Which of the following is an interrupt according to temporal relationship with system clock ?
(A) Maskable interrupt
(B) Periodic interrupt
(C) Division by zero
(D) Synchronous interrupt


Answer: (D)

Explanation: According to temporal relationship with system clock we classify interrupt in two ways:
1- Synchronous: The source of interrupt is in phase to the system clock is called synchronous interrupt. In other words interrupts which are dependent on the system clock. Example: timer service that uses the system clock.
2- Asynchronous: If the interrupts are independent or not in phase to the system clock is called asynchronous interrupt.
So, option (D) is correct.
