Three Computer Networking CourseBooks
Understanding Networking Topologies
This course, by Clayton Coulter, is designed to provide you with up-to-date information on networking. The content focuses on local area networks and the technology for connecting them together. It is general enough to give a broad overview of today's technologies and trends, while detailed enough for you to see the inner workings of modern networking.

Glossary of Terms and Acronyms
This course book, written by Professor Professor Yechiam Yemini, aims to provide a comprehensive introduction to networking and distributed computing technologies. Unlike traditional textbooks, it pursues a top-down approach to the topic, starting with the application layer and then describing the transport and network layers, finally covering the physical layer. The Network Book also emphasizes hands-on approach to learning.
