Appendix B. Network Fundamentals

This appendix describes the fundamental concepts that relate to networks and includes the following sections:

The goal of this appendix is to introduce some fundamental concepts and terminology that are the foundation for the other material in the book. After a brief introduction to networks in general, we delve into the communication protocols that are used by network devices; this necessarily includes a discussion of the infamous Open Systems Interconnection (OSI) model. LANs and WANs are described, as are the various devices found in a network. This is followed by ...
