screen savers are used to protect the screen from having an image burned into the screen? true or false ,i think its true
Yes, true -- that's the intention.
Right you are! True.
Yes, that statement is true. Screen savers were originally used to protect screens, particularly CRT (cathode ray tube) monitors, from having a static image burned into the screen. This burn-in effect occurs when a static image remains on the screen for an extended period, causing those pixels to age differently from the rest of the screen.
When a computer is left idle for a specific amount of time, the screen saver activates and replaces the static image with moving graphics or patterns. This prevents a single image from displaying continuously and reduces the risk of burn-in. However, it is worth mentioning that with modern display technologies like LCD (liquid crystal display) and OLED (organic light-emitting diode), burn-in is less of a concern.
