- Linux is a family of open-source Unix-like operating systems based on the Linux kernel.
- Linux was first released on September 17, 1991, by Linus Torvalds.
- Linux also runs on embedded systems, i.e. devices whose operating system is typically built into the firmware and is highly tailored to the system.
- This includes routers, automation controls, smart home technology (like Google Nest), televisions (Samsung and LG Smart TVs use Tizen and WebOS, respectively), automobiles (for example, Tesla, Audi, Mercedes-Benz, Hyundai, and Toyota all rely on Linux), digital video recorders, video game consoles, and smartwatches.
- The Falcon 9’s and the Dragon 2’s avionics use a customized version of Linux..
