Meaning and Definition
A technical term for a type of floppy disk or magnetic data storage medium with the lowest storage capacity in its generation.
Refers to older technology, typically 5.25-inch or early 8-inch floppy disks, with a data storage capacity significantly lower than later 'double density' or 'high density' formats. Can metaphorically describe something obsolete, of low capacity, or from an early stage of development.
