Just enough operating system

Just enough operating system (JEOS) is like a “light” version of an operating system (OS). It's designed to only have the things you need to run a specific task - not extra stuff like large applications or games. JEOS is used in servers and other devices that only need to do one thing, like store data or host a website. This can help them save space and run faster, since they don't have to juggle a bunch of different applications.
