Ubuntu, which has been rated as one of the most popular operating systems, is a free and open source Linux-based operating system that is built around the Linux kernel. It comes with some good open source software applications that you can work on.
The name “Ubuntu” comes from Zulu and Xhosa languages and the principle of Ubuntu is said to be, “a person is a person only through other people.” This can be better explained through the following quote:
“A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed.” — Archbishop Desmond Tutu
Ubuntu is not only free of charge but people are also allowed to improve upon it anyway they wish to, which means they can change and fix the software in any way.
This proves to be advantageous when developing programs. Users have no restriction on the number of systems they use it on and the installation is extremely simple.
Ubuntu, sponsored by Canonical a European-based company owned by Mark Shuttleworth, does not cost anything and is free software that does not carry any software licensing charges. In fact, the operating system CDs will be shipped free throughout the world.
By making it totally free and open, the company has been able to leverage the knowledge of other developers instead of doing all the development in the company.
Canonical is said to make money in spite of giving the software for free, from its engineering services and commercial support contracts, which it offers globally to the wide range of customers, from government organizations to Fortune 500 companies and from schools to research institutes. This paid support makes it possible for the company to earn revenues.
Ubuntu can be installed very easily and to the hard disk from the Live CD environment without having to restart the computer before installation.
Ubuntu comes in many versions as well as different variants. Here are the official variants:
• Kubuntu: Ubuntu with the KDE environment instead of Gnome. It is also a part of the Ubuntu project and showcases the complete potential of the KDE desktop. It shares the same underlying system as Ubuntu.
• Edubuntu: Is another subproject of Ubuntu that focuses on education. This is designed to be used in classrooms and contains many educational applications, such as KDU Edutainment Suite, Gcompris and Schooltool Calender.
It makes it possible for even educators with no technology expertise to set up computer labs or even undertake the task of setting up an online learning environment in a couple of hours. They will also be able to administer that environment. It is also suitable for use by children at homes.
• Xubuntu: Ubuntu using the XFCE desktop environment instead of Gnome. It has been created keeping in mind people who own computers that are not powerful or even those that need an efficient desktop environment on powerful systems.
• UbuntuStudio: Ubuntu focused on multimedia production.

The default desktop environment for Ubuntu is Gnome, which is a leading UNIX and Linux desktop suite and development platform. An alternative choice to the default Gnome desktop environment is Kubuntu that offers KDE, another leading UNIX and Linux desktop.
The default desktop for Xubuntu is Xfce. Since Ubuntu, Kubuntu, Edubuntu, Xubuntu, and Gobuntu all share the base; any one of them can be installed easily on the other.
The Linux kernel is the heart of the Ubuntu operating system. A kernel provides the communication bridge between the hardware and software and is an important part of an operating system.
