Most Recently Used (MRU) is a method for managing data in computing, where the most recently accessed items are prioritized for quick retrieval. This approach is commonly used in applications like file explorers and web browsers, allowing users to quickly access files or websites they have recently interacted with. In MRU systems, the list of items is updated each time a new item is accessed, pushing older items down the list. This can enhance user experience by reducing the time spent searching for frequently used items, making it easier to return to recent tasks or documents.
