What is the difference between binary semaphore and mutex?

Question

Chitra S · Accepted Answer

The main difference is that a mutex is for mutual exclusion with ownership, meaning the same thread must unlock it, while a binary semaphore is for signaling between threads, and any thread can signal it. Mutexes have built-in features like priority inheritance, whereas binary semaphores do not. Mutexes are ideal for protecting a single shared resource, while semaphores are better for controlling access to a pool of resources or for general synchronization.
