Ubuntu is a Debian-based Linux operating system and distribution for personal computers, smartphones and network servers. It uses Unity as its default user interface.

The popularity of Ubuntu is such that it is used on International space station and is behind the world’s largest supercomputer. It runs the servers of popular online services like Netflix, Snapchat, Pinterest, Reddit, Dropbox, PayPal, Wikipedia, and Instagram, in Google, Tesla, George Hotz, and Uber cars. It is also employed at Bloomberg, Weta Digital and Walmart.The Brigham Young University is using Ubuntu to control the Mars Rover.
