Can you explain what semaphores are and their functioning? Also, in what scenarios would you use them?

Hard Difficulty

Hard questions require advanced understanding and critical thinking. Here, your problem-solving skills are key, as these questions often involve complex scenarios needing in-depth analysis and well-structured responses.

Technical Knowledge question

Technical Knowledge questions test your understanding of specific technologies and concepts. Showcase your depth of expertise in relevant technical areas and how you stay current with evolving industry standards and practices.

Here's a Hint

Define semaphores as synchronization primitives, explain binary vs. counting semaphores, and describe typical operations. Include practical examples like resource allocation, producer-consumer problems, and critical section protection.
