“Ubuntu is a community developed, Linux-based operating
system that is perfect for laptops, desktops and servers. Whether
you use it at home, at school or at work Ubuntu contains all the
applications you need – a web browser, presentation, document and
spreadsheet software, instant messaging and much more.“Ubuntu is and always will be free of charge. You do not pay any
licensing fees. You can download, use and share Ubuntu with your
friends, family, school or business for absolutely nothing.“Ubuntu is designed with security in mind. You get free security
updates for at least 18 months on the desktop and server. With the
Long Term Support (LTS) version you get three years support on the
desktop, and five years on the server and there is no extra fee for
the LTS version.”
