Question

Which is the mechanism to enforce limits on the access of a resource when multiple threads are executed?

Answer 1

filter feature.............

Answer 2

The mechanism in question here is known as a Semaphore. The purpose of a Semaphore is to limit the access of threads concurrently to the shared resources.

It is great for non-inclusive locking implementation. This essentially enables concurrency limiting. It is different from a Mutex because Mutex allows for synchronization across processes. Therefore it allows multiple threads to access the resource.
