The two kinds of semaphores are:
- Binary Semaphores : These semaphores can only take two values, 0 or 1. They are used to provide mutual exclusion, ensuring that only one process or thread can access a critical section or shared resource at a time. Binary semaphores are often used to implement locks
- Counting Semaphores : These semaphores can take any non-negative integer value. They are used to manage access to a resource that has multiple instances available, allowing multiple processes or threads to access the resource simultaneously up to the count limit
In summary, binary semaphores are for exclusive access (single unit), while counting semaphores allow multiple concurrent accesses (multiple units)
