Binary Semaphore

Binary Semaphore

Binary semaphores are semaphores that can only assume the values 0 and 1. They are used for implementing the locks by using signaling mechanisms to achieve mutual exclusion. Here, if the value of the semaphore is 0, it means it is locked, so the lock is unavailable. If the value of the semaphore is 1 it means it is unlocked, so, the lock is available in binary semaphore....

Mutex

A mutex provides mutual exclusion, either the producer or consumer can have the key (mutex) and proceed with their work. As long as the buffer is filled by producer, the consumer needs to wait, and vice versa. At any point in time, only one thread can work with the entire buffer. The concept can be generalized using semaphore....

Difference Between Binary Semaphore and Mutex

...

Conclusion

In essence, both binary semaphores and mutexes help manage access to shared resources in a multi-threaded environment, but their primary difference lies in their intended use cases. Binary semaphores are often used for signaling and coordination between threads, while mutexes are focused on providing mutual exclusion to ensure thread-safe access to critical sections....
