GNU/Linux - Computer Definition
The operating system created in 1992 by combining the GNU system, the Linux kernel and other software. Although "Linux" is the name most widely heard, many prefer to use "GNU/Linux" to give credit to the GNU Project, which contributed essential components to the system. The Linux kernel provides the nucleus of the system, but a "Linux distribution" includes a huge amount of software from the GNU Project and other sources (see Linux distribution). The basic GNU/Linux operating system is open source software because it complies with the "free software" philosophy of the Free Software Foundation. However, most distributions of GNU/Linux include some programs that are neither free nor open source. See GNU Project, GNU Hurd, Linux, free software and open source.
