Physical file organization refers to the way data is stored on a physical medium, such as a hard drive or SSD. It involves the arrangement of records in a specific format, such as sequential, heap, or indexed, to optimize data retrieval and storage efficiency. This organization impacts how quickly and effectively data can be accessed, updated, and managed within a database or file system. Proper physical file organization is crucial for performance, especially in systems with large volumes of data.
