Explain how the disabling and enabling of interrupts is useful in implementing mutual exclusion primitives on uniprocessor systems.
What will be an ideal response?
Actually, implementing mutual exclusion primitives in this way is quite straightforward. When a thread executes enterMutualExclusion(), all interrupts are disabled. Then the thread can run its critical section uninterrupted. When the thread executes exitMutual- Exclusion(), interrupts are re-enabled.
