MRU stands for "Most Recently Used," a method commonly employed in computer systems to manage data and resources. It prioritizes the items that have been accessed most recently, making them quicker to retrieve. This approach is often used in cache management, where frequently accessed data is stored for faster access. In software applications, MRU lists help users quickly find and open files or documents they have worked on recently. For example, in programs like Microsoft Word or Adobe Photoshop, the MRU feature displays a list of the last opened files, enhancing user efficiency and convenience.
