A screensaver is a type of immobile picture that can be added into your screen’s settings and is activates when there are long periods of inactivity in the keyboard or in the mouse.

The screensaver’s most important task is to save the screen’s energy and prevent it from wearing out due to its unnecessary usage. Even though nowadays they are used with a fun purpose, they provide security to the information, because it can be set up to have a keyboard every time the screensaver is activated and it will ask for a password or key to keep working on the computer.
The screensaver was originally born as a prevention before any permanent engraving of the screen, because, in the first monitors a phenomenon occurred in which the prolonged expositions of an image made the electrons of the rays produced by the monitor to remain permanently stick to it, as some sort of burn; that happened because of the refreshing of the screen, which, sometimes, is not continuous in some zones of the monitor.
