Basic Computer/IT QUESTION #11449
Question 1
Which of the following are the most widely used secondary storage mediums?
  • Magnetic storage
  • Flash memory
  • Optical
  • Both magnetic and optical✔️
Correct Answer Explanation
The most common storage devices are magnetic (Hard Disk Drives, magnetic tape) and optical (CD, DVD, Blu-ray). Magnetic storage uses magnetised platters; optical uses laser beams. Flash memory (SSDs, USB drives) is increasingly replacing both due to faster speeds and no moving parts.
