The official mascot of the Linux kernel is a penguin character named Tux. This Linux logo was suggested by Linus Torvalds in 1996. The name Tux is derived from (T)orvalds (U)ni(X).
The Linux OS is frequently packaged as a Linux distribution for both desktop and server use, and includes the Linux kernel (the core of the operating system) as well as supporting tools and libraries. Popular Linux OS distributions include Debian, Ubuntu, Fedora, Red Hat and openSUSE.
