In the previous chapter, we introduced the new Raspberry Pi Zero W board. We also mentioned several accessories that someone could buy with the board to make their life easier without struggling to connect everything together. Before developing a project with that board, there is something that must be mentioned and analyzed from different perspectives. Since Raspberry Pi Zero W will be connected to the internet, it's time to talk about Internet of Things and networking. In this chapter, we will go through the following topics:
- Internet of Things
 - Basic communication protocols
 - Pi Zero setup
 - Router setup
 - Network administration
 - Security
