Traditional computers had CRT monitors. What do you mean by CRT?

Correct option is A

CRT (Cathode Ray Tube) is the technology used in traditional computer monitors and televisions. It operates by using electron beams to strike phosphor-coated screens, producing images. This technology has largely been replaced by modern displays like LCDs and LEDs.
Important Key Points:
1. CRT monitors were bulky and power-intensive compared to modern flat-panel displays.
2. The phosphor coating on the screen creates visible light when hit by electron beams.
3. CRT technology was widely used in televisions and early computer displays.
Knowledge Booster:
· Computer Ray Tube: Incorrect interpretation of CRT.
· Commercial Ray Tube: Not a valid term.
· Copper Ray Tube: Unrelated to CRT technology.
· Modern monitors, such as LCD (Liquid Crystal Display) and LED (Light Emitting Diode), are more energy-efficient and compact compared to CRTs.
