Summary
This chapter covered various networking technologies, both current and emerging. Beginning with a discussion on how networks function through an overview of the OSI model and the TCP/IP model, this chapter then took you through an overview of multi-layer protocols and converged protocols. You also examined modern concepts such as micro-segmentation and various wireless networking technologies.
Now that you understand how protocols communicate and the challenges provided by multilayer protocols, you are ready to explore the next chapter, which focuses on the security of network components and their protocols.
