Networking

2. Network Organization
In-vehicle networking is creating a quiet revolution in automotive technology over the
past two decades.
A network organization is a collection of autonomous firms or units that behave as a
single larger entity, using social mechanisms for coordination and control.

12. Introduction to CAN bus system
The Controller Area Network (CAN) is a serial communication bus designed for robust
and flexible performance in harsh environments, and particularly for industrial and
automotive applications.
