Storage device that uses lasers and lights as its technology of reading and writing information is known as _______.

  • (A) Magnetic storage 
  • (B) Cloud storage
  • (C) Optical storage
  • (D) Paper storage
The correct option is (C) Optical storage. The principle of optical storage is based on the idea of using a laser to both read and write the data. A gentle laser beam is shone on the surface of the spinning disc (like a CD, DVD, or Blu-ray disc), and the laser is focused on the tiny pits and flatlands on the disc. The reflection of the laser light from the surface is used to represent the data in terms of 0s and 1s.
