With respect to computer storage devices, which of the following is/are magnetic storage device(s)? A. CD-R B. DVD-RW C. Flash memory stick D. External Hard Drive Choose the correct answer from the options given below: Correct Answer D only

Magnetic storage is frequently utilised in comparison to other storage technologies.

Key Points

  • Magnetic data storage is one of the most extensively utilised methods of digital data storage.
  • The magnetic surface is divided into very small sections, each with a magnetization that is relatively uniform.
  • Magnetic storage is read-write allowing you to reuse the store space by removing older data.
  • It stored data outside the computer for a long period of time. 
  • The main disadvantage of magnetic storage is the slowness with which data may be accessed.
  • Magnetic storage for nonvolatile data storage in the form of an external hard drive. 

​Therefore, Magnetic storage is an external hard drive with respect to the computer storage device.

Additional Information

  • DVD stands for digital versatile disc and is a type of optical disc used for data storage and multimedia platforms. It was invented in 1995 and its storage capacity range from 4.7 GB to 17.08 gigabytes. 
  • Compact disc read-only memory or CD-ROM is a type of computer memory that is stored on a compact disc and read by optical means. In 1982, Japanese company Denon developed CD-ROM. 
  • A USB flash drive is a portable storage device with flash memory that is small enough to be carried. It was invented by Fujio Masuoka in the early 1980s.

A long stick of certain length is cut into several equal pieces. When the stick is cut into an equal piece of 24 cm each or 15 cm each or 27 each, then every time a piece of the stick of 3 cm length remains left. This stick can be cut into ‘x’ equal pieces of 33 cm length, then what is the least value of ‘x’?
Assertion (A): A stick is dipped in water in a slanting position. If observed sideways, the stick appears short and bent at the surface of the water.
Reason (R): A light coming from the stick undergoes scattering from water molecules giving the stick a short and bent appearance.
