What Is Linux? A Beginner Guide to the Open Source Operating System
You use Linux every day without realizing it. Android phones run on Linux. Most websites you visit are served by Linux servers. Smart TVs, routers, and even cars use Linux. But what exactly is this operating system that runs so much of the world?
What Is Linux?
Linux is an open-source operating system, similar to Windows or macOS, but with a fundamental difference: it is completely free and anyone can view, modify, and distribute its source code. Created by Linus Torvalds in 1991, Linux has grown from a hobby project into the most widely used operating system on the planet.
Why Do People Use Linux?
People choose Linux for many reasons. It is free, secure, and highly customizable. Unlike Windows, Linux does not collect your data or show ads. It runs well on old hardware, making old computers usable again. Developers love Linux because it includes powerful programming tools out of the box. Privacy-conscious users choose Linux to avoid Microsoft and Google tracking.

What Are Linux Distributions?
A Linux distribution (distro) is a version of Linux packaged with specific software and desktop environments. Think of Linux as the engine and distributions as different car models using that engine. Popular distributions include Ubuntu (beginner-friendly), Linux Mint (Windows-like), Fedora (cutting-edge), and Debian (stable).
