A portable memory storage device is called?

• A. USB drive
• B. CD-ROM
• C. SD card
• D. Floppy disk

Answer: (D)

A portable memory storage device is any removable medium that can hold data and be moved between computers. The floppy disk fits this idea well: it’s a small magnetic disk inside a protective sleeve that you can remove from a computer and carry to another, then insert into a drive to access or transfer data. This classic example is often used to illustrate removable, transportable storage. While USB drives and SD cards are also portable storage today, the floppy disk embodies the traditional concept of portable, removable memory in many introductory explanations. CD-ROMs are optical and typically read-only, which makes them less representative of writable portable storage in this context.
