A mutex is a binary semaphore. Semaphores in general are counting semaphores. You can have n threads in a critical section using a semaphore but only one using a mutex.

A little change to earlier comment.. a semephore allows multiple threads to share a resourse...

Mutex is a semaphore with count one. Mutex serialises the access to a reentrant code. While semaphore restricts the number of simultaneous users to a shared resource.

Actually, Mutex and Binary semaphores are different.

The main difference is that, in case of mutex "The thread that locks the mutex should only release the mutex".
