WebJan 3, 2024 · A Binary Semaphore is a semaphore whose integer value range over 0 and 1. It is nothing, but similar to a lock, with two values: 0 and 1. Here 0 means busy, while 1 means free. The idea behind using a binary semaphore is that, it allows only one process at a time to enter the critical section (thus allowing it to access the shared resource). WebSep 28, 2024 · Binary semaphore is also known as mutex lock. Counting semaphore – It is helpful to control the access to a resource which include multiple instances. These values have an unrestricted value domain. It counts the number of available resource. 2. Spinlock : Spinlock is a locking system mechanism.
