Which among the following is not a magnetic storage?
- A.Winchester disk
- B.Floppy Drive
- C.Memory Card
- D.Magnetic Tape
Correct answer
Explanation
The correct answer is C, Memory Card. A memory card keeps data in flash memory, a semiconductor chip with no moving parts, so it is solid-state storage and not magnetic. The data sits as trapped charge in floating-gate transistors, which is why SD cards, pen drives and solid-state drives are fast, silent and able to take a knock. Magnetic storage works quite differently: it records data as patterns of magnetised spots on a coated surface that a read-write head passes over. Option A is wrong because the Winchester disk is the early IBM name for the sealed hard disk drive, which is magnetic. Option B is wrong because a floppy drive writes on a thin magnetic plastic disc. Option D is wrong because magnetic tape, still used for archives and backups, is a plastic ribbon with a magnetic coating. Exam tip: sort storage by how it records — magnetic (hard disk, floppy, tape), optical (CD, DVD, Blu-ray) and solid-state or flash (memory card, pen drive, SSD).
