CRT full form in computer

CRT stands for Cathode Ray Tube. In computing, CRT is a type of display technology used in older computer monitors and televisions. A CRT display works by firing electrons at a phosphor-coated screen to create a visible image. The CRT technology was widely used in the 20th century but has since been replaced by more modern displays, such as LCD and LED, due to its large size, weight, and lower energy efficiency.
