Question

Accepted Answer

Locks are synchronization mechanisms used to control access to shared resources in multi-threaded environments.

Locks prevent multiple threads from accessing shared resources simultaneously.
They ensure that only one thread can access a shared resource at a time.
Locks help in preventing race conditions and maintaining data integrity.
They can be implemented using various techniques such as mutexes, semaphores, or monitors.
In a non pre-emptive uni processor system, where only one task is executed at a time, locks may not be necessary as there is no concurrent access to shared resources.
