Can you explain the differences between locks and semaphores?
Sure! Locks and semaphores are both synchronization primitives used in concurrent programming, but they serve different purposes.
What is a lock used for?
A lock is used to ensure that only one thread can access a resource at a time, preventing race conditions.
And what about semaphores?
Semaphores are used to control access to a resource pool, allowing multiple threads to access a limited number of resources.
Can you give an example of when to use each?
Certainly! Use a lock when you need exclusive access to a single resource, and use a semaphore when you want to limit access to a fixed number of resources.
