Question

Quizplus · Accepted Answer

A reader-writer lock is most useful when there are a significantly large number of reader processes attempting to read in the critical section. This is because a reader-writer lock allows multiple readers to access the critical section simultaneously, but only one writer at a time, ensuring that data is not overwritten or corrupted. In the case of a bounded buffer, a semaphore or mutex would be more appropriate. Option A and Option B are not relevant to the use of a reader-writer lock. Option C is incorrect because a small number of readers would not require the use of a reader-writer lock.
