Raspbian is the official OS for the Raspberry Pi.
Based on the Linux-OS Debian, it has been repeatedly updated since 2012 to make it easier to use and to expand its default software library.
The OS bundles web browsing, office and programming software and has been overhauled to make it simpler to use and more attractive. Recent improvements have seen the introduction of the PIXEL desktop, the addition of a startup wizard and the launch of Raspbian's own take on an app store.
Overall, the OS strikes a great balance between being welcoming to novice users while packing a wide range of general and coding-related software.
