Translations:Screensaver/4/en

The original purpose of a screen saver was to prevent a constant image from being burnt into the tube screens of the 1980s and early 1990s during long breaks from work. With more modern CRT monitors and flat screens there is no longer a risk of burn-in, so screensavers are now only used for entertainment or for reasons of data protection. The screen saver prevents curious people from seeing what a user has on the screen while they are away. The optional prompt for entering a password to reactivate the desktop when the screensaver is closed can also prevent unauthorised access.
