Screen savers are some of the most commonly used software types by computer users. They were originally invented to help prevent phosphor burn-in on computer monitors. This original use is not as vital as it used to be because technology has changed and monitors are not nearly as likely to suffer from this as they were in the past. However, screen savers have another benefit that will continue to be important now and into the future. Screen savers are very important security tools for computers that may be in a shared environment.
If a computer user has a screen saver installed with the correct settings, they can feel secure that if they leave their computer running, it cannot be accessed by those who may pass by or decide to try and use the computer. Screen savers can be set up to require a password to deactivate them and continue the computer session. Setting your screen saver up like this is a very smart move, because then you can easily control who has access to your computer and files. This can be vitally important for those who have a shared work space.
Another use of screen savers is for entertainment. In the beginning, they were very simple and only provided a useful service. However, software developers saw the potential for more interesting screen savers and have created thousands of different screen savers. Because of this, there is a screen saver that will fit nearly every user’s personality. Many of these screen savers are more than simple designs or slide shows; they are actually small applications that can do a variety of different things. There are screen savers that are set up like video games and there are screen savers that can use idle system resources to conduct research or do important tasks. Screen savers have continued to adapt to the needs and wants of computer users through the years, ensuring they remain useful and desirable applications.
