Almost all hardware devices show up in physical memory somewhere. On the Raspberry Pi single-board ARM computer, the external pins called general-purpose input/output (GPIO) pins are accessible to the CPU as a range of physical memory addresses.

Raspberry Pi OS is a free operating system based on Debian, optimised for the Raspberry Pi hardware, and is the recommended operating system for normal use on a Raspberry Pi. The OS comes with over 35,000 packages: precompiled software bundled in a nice format for easy installation on your Raspberry Pi.
