A compact operating system that provides immediate access to the Internet via a browser as soon as the power is turned on. An instant-on operating system also allows access to local applications such as a media player or photo editor. Typically a Linux version, it enables users to turn their computers on and quickly retrieve email, look up something on the Web or play music without waiting the long time it takes to boot up the primary operating system, which is usually Windows.
