An example of an AI chatbot conversation about locks and semaphores in programming.
What are locks and semaphores in programming?
Locks and semaphores are synchronization primitives used to manage access to shared resources in concurrent programming.
Can you explain how a lock works?
A lock allows only one thread to access a resource at a time, preventing race conditions by blocking other threads.
What about semaphores? How do they differ from locks?
Semaphores can allow multiple threads to access a resource up to a certain limit, while locks only allow one.
Can you give an example of when to use a semaphore?
Use a semaphore when you have a pool of resources, like database connections, and want to limit the number of concurrent accesses.
