Question

Quizplus · Accepted Answer

The concept that is enforced by semaphore operations is mutual exclusion, which ensures that only one operation at a time can access a shared resource. This prevents conflicts and race conditions that might occur if multiple operations were allowed to execute simultaneously. Option A is incorrect as mutual execution is not a valid term. Option B is incorrect as mutex is short for mutual exclusion and is essentially the same as option D. Option C is incorrect as signal exclusion is not a commonly used term in relation to semaphore operations.
