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.
