F indicates that the records are fixed length.
B indicates that the records are blocked. |

F (Fixed)
One physical block on disk is one logical record.
All the blocks/records are the same size.
This format is seldom used.
FB (Fixed Blocked)
Several logical records are combined into one physical block.
Provides efficient space utilization and operation.
Commonly used for fixed-length records. |
