"The explanation of the OSI is difficult and this chapter does an excellent job of breaking it down and explaining how they relate with one another. Very accurate and had an excellent flow from one topic to another. Chapter 4 best chapter yet, it covered several very confusing topics, TCP/IP protocol stack and DNS/DHCP and described the processes in simple to understand terms and gave examples. I liked how the TCP/IP stack was linked to the OSI model and the explanation of IPv4 addressing and IPv6 addressing comparisons was excellent. The delivery of the material was excellent. It took a difficult topic that many students have problems with and simplified it to a degree but didn't lose the complexities of the information. I think that the Hands-On projects are valuable to all of the students and can be completed by those in class or via distance learning."
