How do lock-based queues work?

Can you explain how lock-based queues work?

Sure! Lock-based queues are data structures that use locks to manage access to the queue, ensuring that only one thread can modify it at a time.

What are the advantages of using lock-based queues?

The main advantages include thread safety, preventing race conditions, and ensuring data integrity during concurrent access.

Are there any downsides to using them?

Yes, they can lead to performance bottlenecks due to contention, especially if many threads are trying to access the queue simultaneously.

How do they compare to lock-free queues?

Lock-free queues allow multiple threads to operate without locks, which can improve performance but may be more complex to implement.
