A Cathode Ray Tube (CRT) is a type of which computer device?

  • Keyboard
  • Mouse
  • Monitor
  • Motherboard
Correct Answer: C. Monitor

Detailed Explanation

A Cathode Ray Tube (CRT) is a technology historically used in computer monitors and television displays to produce images on a screen. Therefore, Option C (Monitor) is the correct answer.


A CRT monitor uses an electron beam inside a large glass tube to create images on a phosphorescent screen. When the electron beam strikes specific points on the screen, those points produce light, forming the text, graphics, and images displayed to the user. CRT monitors were widely used before modern LCD, LED, and other flat-panel displays became common.


One of the most noticeable characteristics of CRT monitors is their large and heavy design. Unlike modern flat-panel displays, CRT monitors require considerable space because the tube extends deeply behind the screen. They also generally consume more electricity than newer display technologies.


Key Points:



  • CRT: Cathode Ray Tube. 

  • Used in older computer monitors and televisions.

  • Produces images using an electron beam and a phosphorescent screen.

  • CRT monitors are generally large and heavy.

  • Modern monitors commonly use LCD, LED, or other flat-panel technologies.
