Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. Ubuntu is an operating system just like Microsoft Windows, Apple Mac etc. Linux Ubuntu is basically a platform where applications can be installed, emails can be sent and received, and you can surf the Internet too. Everything you can do in Microsoft WIndows Operating System, you can do in Linux Ubuntu – and more.
