Why do we need Mutex if we have Semophers

Question

Accepted Answer

Mutex and Semaphores serve different purposes in managing concurrent access to shared resources.

Mutex is used to provide exclusive access to a shared resource, while Semaphores can be used to control access to a shared resource by multiple threads.
Mutex is binary in nature, meaning it can only be in two states - locked or unlocked, while Semaphores can have multiple states.
Mutex is typically used for protecting critical sections of code, while Semaphores can be used for synchronization and coordination between threads.
In some cases, both Mutex and Semaphores may be used together to provide more complex synchronization mechanisms.
For example, a Mutex can be used to protect a shared resource, while a Semaphore can be used to limit the number of threads that can access the resource at any given time.
