Splash screen
Alternatively referred to as a boot screen, boot skin, or welcome screen. The splash screen is an introduction page that is displayed as a program or computer is loading or booting. For example, when a Microsoft Windows computer is starting up, there is a Windows splash screen that is displayed while Windows is loading. Usually, the splash screen can include a logo or another image, and a company name, and sometimes the company's slogan. The picture below shows an example of the BIOS splash screen for a Dell computer.
A splash screen can also be used on websites. For example, a website splash screen may restrict access to a site, requiring a visitor to log in before gaining access to the site. It may also be used to allow a visitor to choose their native language or a lower bandwidth version of the site. Splash screens can also be used as a method of advertising. They may be built using Flash programming, for animation or video playback, or they can be built with HTML and CSS for more basic functionality.
