Understanding Linux
Origins of Linux
- Linux originates from UNIX, the leading operating system during the 1970s, 1980s, and 1990s.
- UNIX was powerful but became commercialized and expensive, limiting accessibility.
- The Free Software Foundation (FSF) emerged as a counter-movement to this commercialization.
- The mission of FSF was to provide free software, allowing users to use, study, modify, and distribute it freely.
- The GNU Project, started by Richard Stallman under FSF, aimed to build a completely free operating system.
- GNOME (GNU Network Object Model Environment) is part of the GNU Project.
- GNU stands for “GNU’s Not Unix”, highlighting independence from proprietary UNIX systems.
Birth of Linux Kernel
- In 1991, Linus Torvalds developed the Linux kernel, the core part of the operating system.
- Combining the Linux kernel with GNU tools and utilities created a complete operating system, known as GNU/Linux.
