Difference Between Binary Semaphore and Mutex
| Binary Semaphore | Mutex |
|---|---|
| Its functions based up on signalling mechanism | Its functions based up on locking mechanism |
| The thread which is having higher priority than current thread can also release binary semaphore and take lock. | The thread which has acquired mutex can only release Mutex when it exits from critical section. |
| Semaphore value is changed according to wait () and signal () operations. | Mutex values can be modified just as locked or unlocked. |
| Multiple number of threads can acquire binary semaphore at a time concurrently. | Only one thread can acquire mutex at a time |
| Binary semaphore have no ownership. | There is ownership associated with mutex because only owner can release the lock. |
| They are faster than mutex because any other thread/process can unlock binary semaphore. | They are slower than binary semaphores because only thread which has acquired must release the lock. |
| If you have number of instances for resource it is better to use Binary semaphore. | If you have single instance for resource it is better to use mutex. |
Difference between Binary Semaphore and Mutex
Binary Semaphore and Mutex are both synchronization mechanisms used in concurrent programming to control access to shared resources and prevent race conditions. However, they have different characteristics and use cases
