Category: GNU/Linux
GNU is a Unix-like computer operating system developed by the GNU Project. It is composed wholly of free software. It is based on the GNU Hurd kernel and is intended to be a “complete Unix-compatible software system”. GNU is a recursive acronym for “GNU’s Not Unix!”, chosen because GNU’s design is Unix-like, but differs from Unix by being free software and containing no Unix code.
Development of GNU was initiated by Richard Stallman in 1983 and was the original focus of the Free Software Foundation (FSF), but no stable release of GNU yet exists as of January 2014. However, non-GNU kernels, most famously the Linux kernel, can also be used with GNU software.
