Linux is an open-source operating system created in 1991 by Linus Torvalds. It is free to use and users can modify the source code. Linux runs on PCs and embedded systems and is growing in adoption due to its low cost, customizability, and wide range of supported programming languages. There are many Linux distributions for both general and specialized use in commercial and non-commercial settings. Linux communities provide support through online forums and user groups.
