Answer 2

Answer:

The correct answer is Option D: Magnetic tapes

Explanation:

Magnetic tape:

• A long, narrow strip of plastic film is covered in a thin, magnetizable coating to create magnetic tape, a medium for magnetic storage.

• Because magnetic tape is prone to deterioration, it is not the best medium for long-term archival storage.

• It is suitable for archiving but not for quick data retrieval because it is the slowest of all the storage media to access data from.

• Data is stored on magnetic tape, which incorporates a thin plastic ribbon.
• It is a sequential access memory. Therefore, the read/write data speed is slower.
