Answer / rajji
Semaphore and mutex are the synchronising mechanisms for shared resources. And critical region is part of synchonizing schemes, means it's a part of process sections.
Normally every process will have 3 sections 1.Entry section 2.critical section 3. exit section
In these critical section is more important which tells us how to manage resources like.
In semaphores if one thread is waiting for resource then other thread which has the resource can signal the waiting thread.
In Mutex if one thead is waiting for resource then it has to wait till resource get released. This is the best mechanism for multithreading.
