Ubuntu is an African word meaning "humanity to all." The creation of Ubuntu began from the open source movement in which the creators of software believe in allowing free access to the source code for the purpose of allowing others to improve the code and then, in turn, share the improvements with others free of charge.
Ubuntu is a completely free linux based open source operating system. It is quickly becoming a popular alternative to proprietary operating systems like the many Windows Operating Systems. Ubuntu is the overarching software program that runs the computer itself. According to the Ubuntu website,
"Ubuntu is an operating system built by a worldwide team of expert developers. It contains all the applications you need: a web browser, office suite, media apps, instant messaging and much more. Ubuntu is an open-source alternative to Windows and Office."
