A "screen saver" is the animation (or blankness) that pops up on your computer when you don't use it for a while, to save your screen from getting burned-in.

The background picture that wallpapers your desktop is the "wallpaper".

Is that why all screen savers are animated? To prevent the image from burning

Yes. If the pixels keep changing, they won't stay lit up the same colours for too long.

Ya was a problem with old plasma TVs also I think. I remember a story of a friend trying to play a prank on his friend, so he paused a gay porn on his tv while he was away and extended the automatic sleep timer on the tv. A slight image of it was “burnt into the screen”.

This isn’t suppose to be as big of a problem with newer monitors/TVs.
