Question

define screen saver in computer

Answer 1

Hi

SCREEN SAVER :
• A computer program that usually displays various images on the screen of a computer that is on but not in use

• An animation or image which replaces an unchanging computer display after a period of inactivity.

• A screen saver is an animated image that is activated on a personal computer display when no user activity has been sensed for a certain time. The original purpose of a screen saver was to prevent burn-in (the burning of an image into the phosphor inside the cathode ray tube after hours of the same image being rescanned). In fact, today's CRT display technology makes burn-in unlikely except under extreme conditions. (On larger displays used for room presentations, burn-in is still a possibility.)
