Quizplus · Accepted Answer

Physical sequential retrieval retrieves records in the order in which they are stored on a disk, whereas logical sequential retrieval retrieves records in the order they are arranged in a file, which may not necessarily correspond to the order on the disk. Immediate sequential retrieval refers to retrieving records without requiring movement of the read/write head, direct retrieval uses a unique key to immediately locate a specific record, and indirect retrieval involves accessing index files to locate individual records.
