Ubuntu 11.04

From Oxxus Wiki

Ubuntu is Linux OS distribution forked from Debian code-base under code name Natty Narwhal. Main goal of this distribution is to provide Linux stable and productive graphical user interface environment, although Ubuntu can be used as a server environment too.

Each Ubuntu's name contains version number of year and month when it's released, latest one came in April of 2011. As it relays on Debian distribution all packages are distributed via deb packages. Being forked from Debian provides huge library of ready-to-go packages available to Ubuntu as well.

Therefore, it comes in two separate distributions, Desktop and Server oriented. Desktop Ubuntu is provided for Desktop and Laptop computers. The applications are optimized to work on such platforms, with strong multimedia backend. Server oriented versions relays on processor and network power, required for server related services.

The most used desktop Ubuntu is Kubuntu, with implemented KDE window manager which has newly developed interface, called Plasma. There are also other versions like Edubuntu, with Gnome, Xubuntu with Xfce window managers. With server release, Ubuntu can have GUI, just like Desktop release though. Both versions come as free distributions and are both maintained under Open Source Community.

Main difference between them is that Server edition offers technology and resources to make a private or public cloud. These services are arranged under UEC community, Ubuntu Enterprise Cloud, which provides virtualization capabilities. With new version, 11.04, an OpenStack, an Iaas Cloud computing is offered as a project of Rackspace cloud by Nasa.
