A background may refer to any of the following:
1. When referring to multitasking operating systems, background is the place an active program is running, but not visible to the user. For example, when listening to music while browsing the Internet your audio program is running in the background.
2. Background is also another way of describing the Microsoft Windows wallpaper.
3. In Linux, a background process is any process started by the user that is running in a Linux environment background. To view your current running background processes use the bg command. A background process should not be confused with a daemon, which is similar, but never requires any input from the user.
4. When referring to a location or position, a background is what is underneath another object. For example, with "this example Text" red is the background color and the yellow text is the foreground.
