Abstract

This chapter begins by discussing a few of the tools that you will use throughout the book. Next, we cover the OSI (Open Systems Interconnection) model and discuss how it relates to networking. We talk about all seven layers of the OSI model. Then we move on to the TCP/IP model and show its relation to the OSI model. We end the chapter discussing well-known port numbers, the different types of networks, and Cisco’s hierarchical internetwork model.
