Analogy — Medium of storage: Video : Cassette :: Computer : ? Select the storage medium for computers that parallels a cassette for videos (legacy media context).

Introduction / Context:
In legacy media contexts, videos were stored on cassettes; early computer data were routinely stored on floppy disks. The relation is “content/device : typical storage medium.”

Concept / Approach:
Choose a medium, not an abstract noun or process.

Why Other Options Are Wrong:

• Reels: Film medium, not standard for computers.
• Recording: An activity/result, not a medium.
• Files: Logical units, not physical media.
• None of these: Invalid since “Floppy” fits.

Final Answer:
Floppy
