Can you explain the difference between a mutex and a semaphore in the context of multithreading, and provide a scenario where each would be appropriately used?

COVER // CAN YOU EXPLAIN THE DIFFERENCE BETWEEN A MUTEX AND A SEMAPHORE IN THE CONTEXT OF MULTITHREADING, AND PROVIDE A SCENARIO WHERE EACH WOULD BE APPROPRIATELY USED?

A mutex is a locking mechanism that allows only one thread to access a resource at a time, while a semaphore is a signaling mechanism that can allow multiple threads to access a resource up to a defined limit. Mutexes are used when exclusive access is required, while semaphores are used for managing a pool of resources.
