Linux began in 1991 as Finnish student Linus Torvalds' hobby project to create a free Unix-like operating system. Combined with GNU tools and released under an open-source license, it evolved from a solo project to the collaborative foundation powering billions of devices today.

Linux is an open-source operating system that powers most web servers, cloud platforms, and mobile devices. Learning Linux opens career opportunities and provides deep system understanding through its powerful command-line interface.
