Ethernet connects my computers, but will it connect your sensors and devices?

摘要

Ilove my home network. It's Ethernet based and sure beats "sneakernet!" But I learned early on that just because Ethernet is Ethernet, it doesn't guarantee communications-nor does TCT/IP, which carries packets from node to node at near light-speed. TCP-IP is simply a set of transport and network layer protocols; it carries organized packets of data just like the wires carry the data stream.
