What is requirement of synchronization?

Synchronization is essential in multi-threaded or multi-process environments to ensure that shared resources are accessed in a controlled manner, preventing race conditions and ensuring data consistency. It helps coordinate the execution of threads or processes, allowing them to work together without conflicts. By implementing synchronization mechanisms like locks, semaphores, or barriers, developers can manage dependencies and ensure that critical sections of code are executed safely. Overall, synchronization is crucial for maintaining the integrity and reliability of concurrent systems.
