Mutual Exclusion – ME

Question 5. What is a semaphore, and how does it help achieve mutual exclusion?


Answer:

A semaphore is a synchronization primitive that can control access to a resource by maintaining a counter. For mutual exclusion, a binary semaphore (with values 0 and 1) ensures that only one process can access the resource at a time.
