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 Apple \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.
