Probably the most famous of these are Debian and Ubuntu. Debian is a very popular version of Linux originally created by a Purdue grad named Ian Murdock, and named for himself and his wife, Deb (hence, Deb-Ian). Ubuntu is an African word meaning humanity; Ubuntu and its sister project, Kubuntu, are subtitled Linux for Human Beings. Both versions run primarily in graphical mode, and Ubuntu in particular makes it so users hardly ever have to see the command line. Both Debian and Ubuntu use special package managers that help users get Linux programs without running into all sorts of dreadful dependency problems. In other words, if you download one program and you need another to make it work, youll know this up front instead of finding out later when it crashes and burns. Youll also very rarely have to compile any source code using either of these.
