Book Description

Knowing how to install, configure, and troubleshoot a computer network is a highly marketable and exciting skill. This book first introduces the fundamental building blocks that form a modern network, such as protocols, topologies, hardware, and network operating systems. It then provides in-depth coverage of the most important concepts in contemporary networking, such as TCP/IP, Ethernet, wireless transmission, and security. After reading the book and completing the end-of-chapter exercises, you will be prepared to select the best network design, hardware, and software for your environment. You will also have the skills to build a network from scratch and maintain, upgrade, and troubleshoot an existing network. Finally, you will be well prepared to pass CompTIA?s (the Computing Technology Industry Association?s) Network+ certification exam. This book explains concepts logically and in a clear, approachable style. In addition, concepts are reinforced by real-world examples of networking issues from a professional?s standpoint. Each chapter opens with an On the Job story from a network engineer. These real-world examples, along with Hands-on Projects and Case Projects in each chapter, make this book a practical learning tool. The numerous tables and illustrations, along with the glossaries, appendices, and study questions make the book a valuable reference for any networking professional

1.0 out of 5 stars A sad effort - needs serious editing April 30 2009
By BookWORM - Published on Amazon.com
I am just finishing a college course for which the fourth edition of this book was the required text. I will be filing a written complaint with the department head and the administration.

This book is exceedingly frustrating as it contains errors too numerous to mention, starting with the very first review question in chapter one (correct answer is "None of the Above"), obvious since networks preceded floppies! My first computer used cassette tapes for data in and out. It was a year or two before floppy drives became popular. The authors youth and inexperience disqualifies her for such historical dogma.

I have withheld my disgust hoping that things would get better but they didn't. Virtually every week either I or another student would be pointing out errors in either the text or the failure of the correct answer to be among the multiple choices offered for review questions. This continued right through chapter 12, the last we covered in this class. In the review questions for this chapter, #11 and # 12 are more examples of "none of the above". For #11, since 100BASE-RX allows for 300m network length, there should be no obvious issues. The instructor suggested "B. excessive late collisions" was the desired answer, but that would only be true if the author had said SEGMENT length (limited to 100m) instead of NETWORK length (p.105). For number 12, the correct answer, a PERFORMANCE tester, is not among the choices. A simple continuity tester (the supposed correct answer) can't test the frequency response needed to define CAT6 standards (p.645, 654). Question 15 offers an erroneous premise, as the connection from switch would typically go to a patch panel not a punch-down block. Question 19 is rather baseless, since there is no standard for amber or blinking lights. Those things would be MFG/device specific and therefore not generalized. One could assume that something is going on for that port, but without more information such as a device manual that explains what a flashing amber LED indicated, determining exactly what the problem is would be mere guess work, requiring blind component and media testing.

Bottom line: Highly overpriced for this abysmal quality and not worthy of a college level training manual. The prolific amount of errors leads to a huge waste of time as those who try to pay attention to details get side-tracked trying to find some non-existent answers in the text. If these careless errors were not corrected by the 4th edition, I would have little faith that the 5th edition will be any better. At least the publisher could offer an online forum, errata list or document to alert the reader to these problems so they won't waste time on wild goose chases, looking for accurate information.

4.0 out of 5 stars Good for exam, so-so for education Sept. 15 2009
By ScottH108 - Published on Amazon.com
Format:Paperback|Verified Purchase
Unlike many of the reviewers in this thread, I actually found this textbook to be a very useful guide in studying for the 2009 edition of the CompTIA Network+ exam. Admittedly, it was not completely adequate in and of itself; I supplemented with computer-based practice tests (another reviewer has already named names ;-), and would not have fared as well on the exam without them. At the same time, I don't think there's a textbook out there that can substitute for a good set of practice exams, nor for live, human-to-human instruction. IMHO expecting a textbook to provide 100% of what you'll need to pass a fairly complex 90-minute professional exam is a little naive.

As for the book's readability and accuracy, I agree with some of what has been said. The style is awfully dry and there is a tendency to just dump reams of details. On the other hand, reams of details is what the CompTIA exams are about, so I can't totally fault the author for this. I ran across a handful of technical errors, but fewer than I've found in a lot of other IT textbooks. Maybe there's some errors I missed -- I'm fairly new to the networking end of IT (I'm a former programmer) -- but seeing as I also had the sample tests and a live college course to compare with, I don't think I missed a huge number.

After reading the _Network+ Guide to Networks_ cover-to-cover, completing an in-person companion course, and doing about half of the aforementioned sample topic tests, I passed the Network+ exam with a score of 870/900. It worked for me, maybe it will work for you!

1.0 out of 5 stars Waste of Time and Money Feb. 12 2011
By Mike - Published on Amazon.com
This book is the biggest waste of time and money if you are looking to pass CompTia Network+.
This book has a lot of mistakes in it! As for the end of the chapter Questions, they are terribly done. The senerios that are at the back of the book, don't contain enough information for you to really work with.
I can't believe this is the book that they had us use for our class. I passed the CompTIA exam, no thanks to this book. It is way to general.
Out of all the students in both the day and the night classes, only 3 of us passed. The exam contained info that wasn't in the book, and none of us new how to answer.
I feel as though I passed the test on luck. That is not the way I want to pass a test.
All I can say is that I would run from this book and don't look back, as you are not missing anything, if you are looking to pass comptia.

2.0 out of 5 stars One Choppy Read Feb. 5 2011
By Josh Chastain - Published on Amazon.com
Format:Paperback|Verified Purchase
This book was quite a disappointment. I found the material oddly organized, poorly explained and wordy. The one plus is that the book does go into depth on topics if you want to the know the nitty gritty details. Okay, you expect the reading to be dry but this was mega boring and a chore to read. After four chapters I stopped reading this book and picked up the Net+ Passport by Mike Meyers. I found his book much more practical, focused and a surprisingly a good read. The Passport book stays on topic and feeds you the critical info you'll need to know for the test minus the extra fluff. I read Net+ Passport in two weeks and passed the Net+ with a score 801.

Don't get this poorly written text book. The author clearly isn't focused on the main object- obtaining the knowledge to pass the Net+ exam but just covering general topics. Save yourself money and time get the Net+ Passport book
