UNIX is a family of operating systems developed in the late 1960s and early 1970s. A team of researchers initially created it at Bell Labs, a research and development laboratory that AT&T. UNIX owned was designed to be a versatile and powerful operating system that could be used on a wide range of computers.
The GNU Project is a collaborative effort to develop a free, open-source operating system. The project was started in 1983 by Richard Stallman, a software developer, and free-software advocate. The project’s goal was to create a complete operating system that would be entirely free and open-source, meaning anyone could use, modify, and distribute the software without any restrictions.
