What are semaphores and why are they important in programming?
Semaphores are synchronization tools used to control access to shared resources in concurrent programming. They help prevent race conditions.
Can you explain how semaphores work with an example?
Sure! Imagine a parking lot with limited spaces. A semaphore acts like a traffic light, allowing a certain number of cars (threads) to enter.
What are the different types of semaphores?
There are two main types: binary semaphores (which can be 0 or 1) and counting semaphores (which can count up to a specified limit).
How do semaphores compare to mutexes?
Semaphores allow multiple threads to access a resource, while mutexes provide exclusive access to a single thread.
