Summary
Ethernet devices offer tons of different possibilities to connect local and remote devices to each other, and embedded developers can use them for tons of different usages. In fact, the GNU/Linux-based systems offer full and complete support for these devices in both hardware and software. So, developers have to focus their attention on the final target only without losing their time in developing low-level communication protocols.
In the next chapter, we'll see another important networking device class similar to Ethernet devices: wireless networking devices that are commonly known as Wi-Fi.
