What are the advantages of semaphores over mutexes?

Semaphores can allow multiple threads to access a resource, while mutexes only allow one. This makes semaphores more flexible.

Can you explain how semaphores manage access to resources?

Sure! Semaphores maintain a count that represents the number of available resources, allowing multiple threads to proceed if the count is greater than zero.

Are there any scenarios where mutexes are preferred?

Yes, mutexes are preferred when you need strict mutual exclusion, ensuring that only one thread can access a resource at a time.

What are the potential downsides of using semaphores?

Semaphores can lead to complexity and potential deadlocks if not managed properly, as they allow more concurrent access.

How do I choose between using a semaphore or a mutex?

Consider the resource access patterns: use semaphores for multiple access and mutexes for exclusive access. Analyze your specific needs.
