Resource Locks

Resource locks are mechanisms used in computing to control access to shared resources, such as files or data, ensuring only authorized processes can use or modify them at a given time. They prevent conflicts, data corruption, or inconsistencies by serializing access—meaning, only one process can access the resource when locked, while others wait until it's released. Think of it like a digital lock that secures a resource, ensuring orderly, safe, and predictable operations, especially in multi-user or multi-process environments.
