GNOME is a worldwide effort to create a comprehensive desktop environment based exclusively on free software, including software development frameworks, application software for the desktop, and programs that manage application launching, file handling, window, and task management. GNOME is a part of the GNU Project and is compatible with a range of Unix-like operating systems like Linux, as well as Java Desktop System in Solaris.
The GNOME project places a strong emphasis on simplicity, usability, and making things "just work." The name of GNOME originally stood for GNU Network Object Model Environment, though this acronym is no longer in use. The project focuses on building a complete graphical user interface that sits on top of an operating system, giving users the ability to utilize free software that puts them in control of their digital domain.
