Difference between Mutex and Semaphore?

Question

Chitra S · Accepted Answer

A mutex is a locking mechanism that provides exclusive access to a single resource, ensuring only one thread can use it at a time, and the thread that locks it must be the one to unlock it (ownership). A semaphore is a signaling mechanism that controls access to a pool of resources, allowing a specified number of threads to access the resource concurrently based on its integer value.Key differences include ownership (mutexes have it, semaphores don't), their purpose (locking vs. signaling), and how they are used (binary lock/unlock vs. integer counter with wait/signal operations).
