what is the purpose of screensavers?

Screen savers were originally created to protect monitors from "burn-in". Burn-in is when a monitor displays the same thing for so long that a faint image of it seems to be permanently etched on the glass of the monitor. This was really common back in the days where everything was command line, on the old green/black type systems.
Here is a blurb from wikipedia, they can explain the whole thing a lot better than I can. Check the sources for the link. they have a lot of history and other fun stuff in there... more than you ever wanted to know about screen svaers!
"A screensaver is a computer program originally designed to conserve the image quality of computer displays by blanking the screen or filling them with moving images or patterns when the computers are not in use. Today, screensavers are primarily used for entertainment or security purposes."

The purpose of a screensaver is tosave your monitor from image burn in. .A screensaver has one or more moving elements that are constantly moving or active there by changing the screens image . If you leave an image without change on a monitor for an extended period of time it will actually leave an imprint.

The answer involves sort of the "if you don't use it, you lose it"-wisdom: keeping all of the bulbs burning is bad, coz they'd burn out; turning them all off is bad, coz it takes more energy to get them ready to turn back on. I'm sure you have plenty of "wiki"-links that tell you exactly how that works; so instead, the site below makes it even more reasonable to have a screensaver ... with that screensaver on, you earn possible new visitors by letting it run during your time off the computer.

If you leave the monitor and PC on for any period of time, the screensavers job is that "screen saver" it prevents the monitor from obtaining what's called "burn in" from images and data..

Steve N is spot on. Years ago we had computers at work (before screen savers came in) and even when the monitors were switched off you could still see the impression of the main menu burned-in to the monitor

Screensavers were originally designed to prevent 'burn in' on VDUs (after the
same image was displayed on the screen it the phospour layer would be damaged
and cause grey 'after image' of the 'long displayed' image to be permanently
visible..

The used to be to keep your desktop image from being burned into the monitor with old CRT screens, but it's no longer a problem with new monitors. Nowadays they're just for fun.

The screeensaver is some kind of motion picture that comes up in your screen after a few minutes of not moving your computer mouse.
This is like "saving" your screen so you can go somewhere and people won't see what you have on your desktop :)

They used to be used to prevent burn-in on the monitor, but these days you don't need them for that. They're just to have something nice to look at.

If you dont have one it can burn a picture into your screen....if a pic just sits and sits there it will leave an imprint of the picture on your screen....it can happen to T.V.'s too
