Question

A double fault is a fault that occurs when a CPU is trying to call an exception handler.true or false?​

Answer 1

Answer:

The statement mentioned in the question is completely false.

Explanation:

The modern computer's cpu handles a lot of complex data processing jobs and that's why it often faces different types of system fails.

Similarly,the double fault is one of the most common cpu fails which occurs when the cpu completely fails to call an exception handler.

It is often considered as a kernel bug.

Answer 2

The answer is False.

Explanation:

A double fault is a unique exception that occurs when the CPU is unable to invoke an exception handler. The double fault, for example, occurs if a page fault is caused without actual registration of a page fault handler in the Interrupt Descriptor (IDT).

It is similar to catch-all blocks in programming languages with exceptions. A double fault exception occurs if the processor runs into a problem while trying to service or act upon a pending interrupt or exception.
