What are some examples of lock-based structures in programming?
Lock-based structures are synchronization mechanisms used to manage access to shared resources. Examples include mutexes, semaphores, and read-write locks.
Can you explain how a mutex works?
A mutex, or mutual exclusion, is a lock that allows only one thread to access a resource at a time, preventing race conditions.
What is the difference between a mutex and a semaphore?
A mutex is a binary lock that allows one thread at a time, while a semaphore can allow multiple threads to access a resource, depending on its count.
When should I use a read-write lock?
Use a read-write lock when you have multiple threads that need to read data frequently but only occasionally need to write, improving performance.
