Linux is a type of operating system, like Windows or macOS, but it's free and open-source. It's known for being reliable and secure. Instead of being controlled by one company, many people around the world work on it together.

One cool thing about Linux is that you can change almost anything about it to make it work just how you want. It's like having a big box of LEGO bricks and building your own computer system.

People use Linux for all sorts of things, from running servers that power websites to powering tiny computers in smart home devices. It's flexible and can work on many different types of computers, making it a popular choice for tech enthusiasts and professionals alike.
