This is a good textbook for networking information. Some of the material could be explained in more detail to make it more of an introductory topic. A reader with networking experience would find this book a good reference, however, a reader new to the networks might find some of the material a bit light. As a network engineer, I found the information thorough and would work well with other networking material.

Even though the title of the text is "An Introduction to Networking", the author seems to assume that the student or reader knows a lot about the subject matter and terminology. Topics and some definitions are presented, however the author does a deep dive into the topic area quickly.
This text would not be beneficial to students seeking CompTia Network + Certification because many of the terms and concepts tested in the certification exam are not covered in this text.
Content Accuracy rating: 5

Relevance/Longevity rating: 2
Out-of-date information was identified. The text is written in a manner that updates could be made in a straightforward manner.
Clarity rating: 2
The text was difficult to read because precise definitions and content were not provided. Other textbooks and internet sources were used to look up definitions and refresh understanding of technical terms and concepts
Consistency rating: 4
The terminology, framework, and chapter exercises followed a consistent approach.
Modularity rating: 4
The layout of the book is easy to understand and follow.
Organization/Structure/Flow rating: 3
The topics were organized in a logical fashion. It was a challenge to determine the network “big picture” and how the components fit into the picture. The topics make sense to people familiar with Networks. This text would be challenging to people new to Computer Network concepts.
Interface rating: 3
The text is free of navigation problems. The figures and tables were easily identified. An improvement could be made with providing better images or pictures.
Grammatical Errors rating: 4
The text was free of grammatical errors.
Cultural Relevance rating: 5
The text is appropriate for globally-based students.
Many computer concept textbooks have associated software that helps student learn topics and practice. Computer Networks is an area where practice helps students learn. This text did not have associated software available.

Yes, this book is accurate in the major areas that the reviewer read. The entire text was not reviewed.
Relevance/Longevity rating: 4
Yes, the book is up-to-date with the major concepts that do not change (e.g. TCP, IP, UDP) and also includes the latest standards for Wi-Fi. However, some networking technologies will need to be updated as advancements are made (e.g. newer Wi-Fi standards).
Clarity rating: 4
Yes, the text is clearly written. However, the content is very technical and would be challenging for a non-technical person to understand all aspects. It is very straight-forward and appropriate for a technical audience.
Consistency rating: 5
Yes, the book is consistent and uses the same technical terminology throughout.
Modularity rating: 5
Yes the book is very modular and provides many small sections within each chapter for specific topics.
Organization/Structure/Flow rating: 5

Content Accuracy rating: 5
There are some terms here that I have seen presented differently than I have learned them or encountered in industry, but nothing inaccurate.
Relevance/Longevity rating: 5
It would seem that this book is kept rather up-to-date, though much of the content is so fundamental as to not have too much of an expiration date, even in this field.
Clarity rating: 4
I believe the text is clear in most cases. However, I do feel many of the topics become very in-depth, very fast. It would be nice to have some concepts factored out to their basics early in the chapters, then expounded upon later.
Consistency rating: 5
The text does not appear to have any major inconsistencies.
Modularity rating: 4
When viewing online, the table of contents makes the content very browsable. However, when viewing in PDF, the large amount of subheadings for any one chapter can be a bit tough to navigate.
Organization/Structure/Flow rating: 5
As the author notes, there isn't much agreement in how to present this topic, and it can be very difficult to explain one portion without referencing another topic that may not have been presented. I think factoring out some basics and explaining them up front, as this book has done, is a clever way of handling this.
Interface rating: 5
I did not encounter any issues with the text interface.
Grammatical Errors rating: 5
I did not see any obvious grammatical errors.
Cultural Relevance rating: 5
This book is very matter-of-fact, with little in the way of irreverence. Likewise, there isn't much to work with here to be proactively inclusive. I think it works to be somewhat inert in this manner.
Overall, I think that this book is a great resource to have given its open availability. It's not the simplest book, so using this in a first level class or in a more general IT, CS, or survey course will take some shepherding on the part of the instructor. The comprehensiveness does suggest to me that this might be able to fill two courses worth of content, as well. It would be nice to have some of the information factored out, with some of the highlights available as lecture materials. On its own though, I feel this would be a strong resource to use in a computer networking course.
An Introduction to Computer Networksis a free and open general-purpose computer-networking textbook, complete with diagrams and exercises.It covers the LAN, internetworking and transport layers, focusing primarily on TCP/IP. Particular attention is paid to congestion; other special topics include queuing, real-time traffic, network management, security and the ns simulator.
The book is suitable as the primary text for an undergraduate or introductory graduate course in computer networking, as a supplemental text for a wide variety of network-related courses, and as a reference work.
