. A book that makes a concept easier to understand is of great interest to me (and others I am sure) because when something becomes too complicated, we cease to be interested or learn. I think we all can relate to that in some way.

Summary

Part One of this book is titled “Concepts and Fundamentals of Networking.” The goal in this section was to provide the reader with a basic understanding of networking and internetworking concepts. It also provided the difference between packet-switched and circuit-based networks, which is something we should be familiar with to date. The author also presents to us an understanding of network protocols and how they work and finally he introduces the basic components of the Internet and its protocols.

As a review, I have gone back to our Discussion 1b, where we were asked to provide a definition of Packet-Switching vs. Circuit Switching. The definitions are as follows: 1) Packet switching breaks the message into small packets, ships the packets across a network, and reassembles the packets into the original message at the destination, and 2) Circuit switching sets up the entire path before any data is sent. Once the path is set up, the data is transmitted. This transmission may be a two-way exchange. After the communication is completed, the circuit is disconnected.

Additionally, he makes a comparison, between TCP/IP and our U.S. Post Office mail delivery, where data (or in the case of the U.S. Post Office, an envelope or package) is delivered from any point on the network to any other point on the network, with reliability, efficiency and speed which we have covered in our studies to some degree. The author goes into great detail on terminology, which gives an even greater understanding of the field of networking that will also help provide a foundation for the rest of the book.

Part Two, “Internet Applications,” examines how people and other entities interact across a...
