Binary Semaphores

A binary semaphore is a synchronization primitive that can be used to implement mutual exclusion. It can be implemented as a simple integer value that can range between 0 and 1. When the semaphore is 0, no process can enter the critical section. When the semaphore is 1, one process can enter the critical section.
