Linux is a family of open-source operating systems based on Unix and initially developed in 1991. It can run on a variety of devices from phones to supercomputers. Originally developed in C programming language, Linux distributions like Ubuntu, Mint and Fedora now offer graphical user interfaces. Linux sees widespread adoption from governments, militaries, and companies seeking technology independence and is used for everything from embedded systems to enterprise servers.
