.Linux is a top-level domain (TLD) specifically designed for the Linux operating system and its community. It is part of the broader internet domain system and is often used by organizations, projects, and individuals associated with Linux to showcase their work or provide resources. The Linux operating system itself is an open-source software platform, meaning its source code is freely available for anyone to use, modify, and distribute. This has led to a diverse ecosystem of distributions, such as Ubuntu, Fedora, and Debian, each catering to different user needs and preferences.
