What is difference between mutex semaphore?

Question

Accepted Answer

Mutex is a locking mechanism to ensure exclusive access to a shared resource, while semaphore is a signaling mechanism to control access to a shared resource.

Mutex allows only one thread to access the shared resource at a time, while semaphore can allow multiple threads to access the shared resource simultaneously.
Mutex is binary, meaning it has only two states - locked and unlocked, while semaphore can have multiple states depending on the number of threads allowed to access the shared resource.
Mutex is used for protecting critical sections of code, while semaphore is used for synchronization between threads.
Example of mutex: locking a file while it is being written to prevent other processes from accessing it. Example of semaphore: limiting the number of connections to a database.
