Think about all the devices you own, or all the appliances that help power your home. For example, what about the control on your heating and air conditioning system? Chances are, it might be connected to the internet, and also connected to an app on your phone, enabling you to control it easily no matter where you are. These relatively unitelligent devices have minimal computing, but can communicate basic status and context about their position or behavior. Together, the sum of the parts is bigger than the individual node. Your phone can also be considered a node in this same system of “things.”

As we know, these things and the analytics layer that connects them is now called the internet of things (IoT).

Here’s a quick graphical explanation of IoT.
