A DVD is classified as which type of storage device?

  • Hard disk
  • Optical disc
  • Output device
  • Solid-state storage device
Correct Answer: B. Optical disc

Detailed Explanation

A DVD (Digital Versatile Disc) is an optical disc used to store digital data such as videos, software, music, and documents. It uses laser technology to read and write data on its surface, making Option B (Optical disc) the correct answer.


Optical discs store information in the form of tiny pits and lands on a reflective surface. A DVD drive uses a laser beam to read this information and convert it into digital data that the computer can process. DVDs can store much more data than CDs, with a standard single-layer DVD holding 4.7 GB of data and a dual-layer DVD storing up to 8.5 GB.


Key Point:



  • DVD (Digital Versatile Disc): Optical storage device that uses laser technology. 

  • Hard Disk: Magnetic storage device.

  • SSD/Flash Drive: Solid-state storage device using flash memory.

  • Output Device: Produces output and does not store data.


Exam Tip: Remember the common storage media:



  • CD, DVD, Blu-ray Disc → Optical Storage

  • Hard Disk, Floppy Disk → Magnetic Storage

  • SSD, USB Flash Drive, Memory Card → Solid-State Storage
