"Embedded Software for the IoT" by Klaus Elk
With an outset in the history of the Internet and the World-Wide-Web,
the author provides the foundation for understanding loT and the related terms. Modern CPU's and Operating Systems are introduced.
This leads to Best Practices in the many disciplines needed to build and maintain a Connected Embedded System.
