A screensaver is a simple program that appears whenever you leave the mouse or keyboard unattended.
These screensavers were originally designed to protect the computer monitor from phosphor burn-ins. The phosphors that are used to make the pixels in the display would glow at a constant rate. If they are left for a certain period of time, they would actually discolor the glass surface of your monitor.
Today, screensavers are used for entertainment. Most people would use screensavers just for the fun of watching them. Some examples of these screensavers are natural environments like animated waterfalls or fishes, favorite actor/actress, cars, etc.
