What's the purpose of screensavers?

Answer 1

If you leave the same image on a CRT monitors for too long, it will burn an image into the actual screen. So you will see a ghost image forever. The same thing would happen to a tv if te same image was left on it for too long. So they came up with screen savers.

Answer 2

Once upon a time, computers only had screens that showed green letters against a black background. If nothing happened on screen for a long time, the letters would develop a humongous afterglow; sometimes the screen could even be damaged by the incessant electronic bombardment. To counteract the evil effects of static content, someone came up with the idea of a screensaver; if static content hurts the screen, dynamic content will save it...

These days, screensavers can be password-protected, so that no one can access your computer while you are away from it...

Answer 3

In the old days ...before screensavers, people had to be damned sure to turn off monitor because if you left it on and there was text on the screen it would be burned into the screen....
"screensaver"...interpret that literally.

Answer 4

Despite what others may say, the use of screen savers is in fact much more subtle, but also much more important, than you would guess. Their use is to mesmerise anyone who nears the computer (which you are obviously not in the process of using) so that they will, rather than getting on and accessing your personal data, sit there and watch the pretty/cool/other screensaver until such time as you return, and remove them.

Answer 5

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.)

And also, to conserve energy when your computer is not being used (idle).
