Ubuntu is built on the foundation of Linux, which is a member of the \Index{Unix} family. \Index{Unix} is one of the oldest types of operating systems, and together with Linux has provided reliability and security for professional applications for almost half a century. Many servers around the world that store data for popular websites (such as YouTube and Google) run some variant of Linux or \Index{Unix}. The popular Android system for smartphones is a Linux variant; modern in-car computers usually run on Linux. Even the Mac \acronym{OS~X} is based on Unix. The Linux \Index{kernel} is best described as the core\dash almost the brain\dash of the Ubuntu operating system.

\marginnote{While modern graphical \glspl{desktop environment} have generally replaced early command-line interfaces, the command line can still be a quick and efficient way of performing many tasks. See \chaplink{ch:advanced-topics} for more information, and \chaplink{ch:the-ubuntu-desktop} to learn more about GNOME and other desktop environments.} Linux was designed from the ground up with security and hardware compatibility in mind, and is currently one of the most popular \Index{Unix}-based operating systems. One of the benefits of Linux is that it is incredibly flexible and can be configured to run on almost any device\dash from the smallest micro-computers and cellphones to the largest super-computers. \Index{Unix} was entirely command line-based until graphical user interfaces (\glspl{GUI}) emerged in 1973 (in comparison, Apple came out with Mac \acronym{OS} ten years later, and Microsoft released Windows 1.0 in 1985).

The early \acronym{GUI}s were difficult to configure, clunky, and generally only used by seasoned computer programmers. In the past decade, however, graphical user interfaces have grown in usability, reliability, and appearance. Ubuntu is just one of many different Linux \emph{distributions}, \marginnote{To learn more about Linux distributions, see \chaplink{ch:learning-more}.} and uses one of the more popular graphical desktop environments called \acronym{GNOME}.

New users to Ubuntu may find that it takes some time to feel comfortable when trying a new operating system. You will no doubt notice many similarities to both Microsoft Windows and Mac \acronym{OS~X} as well as some differences. Users coming from Mac \acronym{OS~X} are more likely to notice similarities due to the fact that both Mac \acronym{OS~X} and Ubuntu originated from \Index{Unix}. The Unity shell, which is the default in Ubuntu, is a completely new concept, which needs some exploring to get used to it. See \chaplink{ch:the-ubuntu-desktop} for more information about the Unity shell.

[Many applications designed for Microsoft Windows or Mac \acronym{OS~X} will not run on Ubuntu.] For the vast majority of everyday computing tasks, you will find suitable alternative applications available in Ubuntu. However, many professional applications (such as the Adobe Creative Suite) are not developed to work with Ubuntu. If you rely on commercial software that is not compatible with Ubuntu, yet still want to give Ubuntu a try, you may want to consider \gls{dual-booting}. \marginnote{To learn more about \gls{dual-booting} (running Ubuntu side-by-side with another operating system), see \chaplink{ch:installation}.} Alternatively, some applications developed for Windows will work in Ubuntu with a program called \application{Wine}. For more information on Wine, go to \url{http://www.winehq.org}.

[Many commercial games will not run on Ubuntu.] If you are a heavy gamer, then Ubuntu may not be for you. Game developers usually design games for the largest market. Since Ubuntu's market share is not as substantial as Microsoft's Windows or Apple's Mac \acronym{OS~X}, fewer game developers allocate resources towards making their games compatible with Linux. \marginnote{See \chaplink{ch:software-management} to learn more about \application{Ubuntu Software Center}.} If you just enjoy a game every now and then, there are many high quality games that can be easily installed through the \application{Ubuntu Software Center}.

\marginnote{The majority of computers in use today will meet the requirements listed here; however, refer to your computer documentation or manufacturer's website for more information.} Ubuntu runs well on most computer systems. If you are unsure whether it will work on your computer, the Live \acronym{DVD} is a great way to test things out first. Below is a list of hardware specifications that your computer should meet as a minimum requirement.
