E-Book description:
The Raspberry Pi, implemented as a System on a Chip (SoC), really does embody the
very idea of a “system”. There are several large hardware components that make up this complex whole, that we call a system. When we then examine the software side that drives this hardware, we see another body of components that make up the operating system software. As different as hardware is from software, they form a symbiotic relationship. The hardware provides for external interactions with the world while the software internalizes its inputs and determines the external actions that should result.
