ELI5: what is linux
// explanation
What is Linux?
Linux is a software manager for computers, just like Windows or macOS, that tells your computer what to do [1][2]. The special thing about Linux is that it's open-source, which means anyone in the world can look at how it works and help improve it, kind of like a recipe everyone can read and modify [1][4].
Why is it special?
Linux is free and runs on almost everything - computers, phones (Android uses it!), servers, and lots of other devices [2][5]. Because anyone can use and change it, lots of people love helping make it better [1][4].
Who uses it?
Millions of people use Linux, from regular folks to the biggest companies in the world [4]. It powers some of the most popular things you use every day without even knowing it [2].
How do you get it?
You can download Linux for free and install it on your computer, just like you would with Windows, and start using it right away [1][4].
