WebApr 1, 2024 · A semaphore is a generalized mutex. In lieu of a single buffer, we can split the 4 KB buffer into four 1 KB buffers (identical resources). A semaphore can be associated with these four buffers. The consumer and producer can work on different buffers at the same time. Misconception: There is an ambiguity between binary semaphore and mutex.

The default value of a binary semaphore is 1. It is also known as a mutex lock. Counting semaphores: These have values which may range from 0 to any number ‘n’. They have an unrestricted domain.
