WebMar 24, 2024 · Semaphores are, by definition, signaling mechanisms, while mutexes are locking mechanisms. In this way, mutexes provide mutual exclusion for accessing critical code sections. Binary semaphores, in turn, focus on synchronizing the access to critical sections. Thus, mutual exclusion is the primary goal of mutexes. http://gauss.ececs.uc.edu/Courses/c3003/extra/difference-between-semaphore-and-mutex.html
