How do binary and counting semaphores differ?

How do binary and counting semaphores differ?

Binary semaphores can only take values 0 or 1, while counting semaphores can take any non-negative integer value.

Can you give an example of when to use each type?

Use a binary semaphore for mutual exclusion, like controlling access to a single resource. Use a counting semaphore for managing a pool of resources, like a fixed number of database connections.

What are the advantages of using counting semaphores?

Counting semaphores allow for more flexible resource management, enabling multiple threads to access a limited number of resources simultaneously.

Are there any disadvantages to using binary semaphores?

Yes, binary semaphores can lead to deadlocks if not managed properly, as they only allow one thread to access a resource at a time.
