A wallpaper in computing is a digital image used as the decorative background for the graphical user interface on electronic device screens.
In more detail, a wallpaper, also frequently called a background, desktop background, desktop picture, or desktop image, serves as the visual backdrop you see behind the icons, windows, and menus on your screen. As defined, it is a digital image (photo, drawing etc.) used as a decorative background of a graphical user interface on the screen of a computer, smartphone or other electronic device.
