Linux is the free, secure and private operating system that quietly powers most of the internet — and it's ready for your desktop too. Here's what it is and how to start using it.
An operating system is the core software that makes your computer work — it manages your files, runs your apps and connects your hardware. Windows and macOS are operating systems, and so is Linux.
What makes Linux different is that it is free and open source: anyone can use, study and improve it. That openness is why Linux is trusted to run the majority of the world's websites, Android phones, and even the fastest supercomputers on Earth.
Technically, "Linux" is the kernel — the engine at the centre of the system. To get a complete, usable computer you use a distribution (or "distro"), which wraps that engine in a desktop, apps and tools. Linux Lite is a distribution built specifically to be light, familiar and easy for newcomers.
Runs smoothly on old and low-spec hardware where Windows would crawl.
Secure by design, rarely targeted by malware, and free of telemetry or forced accounts.
No licence, no subscription — for you and every computer you own.
Thousands of free apps for web, office, media, photos and more.
Customise the look and behaviour to work exactly how you like.
A welcoming forum and clear documentation to help you along.
Linux Lite is a free, beginner-friendly Linux operating system you can run live from a USB before you install. Give it a go.
