Linux is a free and open-source operating system that is based on Unix. It was originally developed by Linus Torvalds in 1991 and has since become one of the most widely used operating systems in the world, particularly on servers, supercomputers, and embedded systems. Linux is known for its stability, security, and flexibility, and its user base includes individuals, small organizations, and large corporations. Linux also provides users with a wide range of software and tools, including office applications, web servers, programming languages, and games.
