Quizplus · Accepted Answer

Indexed sequential access method (ISAM) is a file structure that is similar to a book index that lists page numbers where certain topics can be found. ISAM files are organized into records, which are stored in a sequential order. Each record has a key field, which is used to identify the record. The index is a separate file that contains the key fields of all the records in the ISAM file, along with the page numbers where the records are stored. When a user searches for a record, the index is used to find the page number where the record is stored. The user can then access the record by reading the page from the ISAM file.
