Gnu

GNU is a free and open-source operating system that was created as a Unix-like alternative, comprising a collection of software components and tools that can be used to build a complete operating system. As a fundamental component of the open-source ecosystem, GNU is relevant to the tech community, particularly developers and system administrators, who rely on its software components, such as the GNU Compiler Collection (GCC) and GNU Core Utilities, to build and maintain a wide range of applications and systems.
