Which two storage devices use a magnetic medium for storing data?

• A. USB Flash Drive and SSD
• B. Optical Disc and Tape Drive
• C. Tape Drive and Hard Disk Drive
• D. Memory Card and Floppy Disk

Answer: (C)

The correct answer highlights two storage devices that utilize a magnetic medium to store data: the Tape Drive and Hard Disk Drive. Tape drives store data on magnetic tape, allowing for sequential access, which is particularly useful for backups and archiving large volumes of data due to their high capacity and cost-effectiveness. The magnetic tape is coated with a magnetic material that allows data to be written and read using a magnetic head. Hard disk drives (HDDs) also employ a magnetic medium, utilizing spinning disks coated with a magnetic material to store data. Data is read and written by moving read/write heads that are positioned over these spinning disks. HDDs are widely used for regular data storage in computers and servers due to their balance of speed and capacity. In contrast, the other options contain devices that do not primarily use magnetic media. USB flash drives and SSDs rely on flash memory, which is non-volatile and does not involve magnetic components. Optical discs utilize lasers to read and write data on the surface of the disc, and memory cards use similar flash technology. Floppy disks did use magnetic media, but they are largely considered obsolete and not a common reference point today. Thus, the correct pairing of Tape Drive and Hard Disk Drive in this context demonstrates
