Screensaver is a type of software, which changes the static image on a desktop with a sequence of dynamically moving images after a certain period of computer inactivity. These software programs appeared long time ago, when computer monitors were not very advanced. At that time, if a static image was left on the screen for a while, it could become permanently "burnt" into a monitor. To prevent this from happening, someone came up with an idea to make screens go blank after a certain period of time and have them display dynamic images instead of a static one.
Modern monitors are no longer in danger; they can display the static images for as long as it is needed without burning them in. However, the screensavers have not disappeared; on the contrary, they have formed a respectable and group of software products. Currently you can find tens of thousands of screensavers that add a personal touch to your computer and fun to your routine work. New technologies advance the screensavers, turning them into the incredible state-of-the-art software.
