OSI Reference Model for Telecommunications Review

Average Reviews:

(More customer reviews)This book was an extremely poor pick. The theory behind the OSI Reference Model is not given at all. The first 3 layers are covered to some basic extent. Overall, the book seems to be a series of long PowerPoint presentations put together in book format. By PowerPoint presentations, I am referring to each page being a list of "bullet-point" phrases that is only there to give a reader a guideline for the lecture she is hearing. Unfortunately, there is no accompanying lecture, so the presentation is totally useless. Altogether, this was a waste of money.

The OSI (Open System Interconnection) reference model is the basis of modern data network design, but it underlines the public switched telephone network (PSTN) as well. For voice engineers learning how to send services over data networks, and for Internet engineers learning how to tap into the PSTN, the OSI model is an ideal point of reference. This book covers roles, functions, definitions and the fundamentals that are required of entry-level personnel.

CompTIA Network+ Certification Study Guide, Fourth Edition (Certification Press) Review

Average Reviews:

(More customer reviews)While this is an informative book, especially concerning Microsoft networking utilities and features, there were definitely some areas on the Network+ 2009 N10-004 test (just took it today, and passed, but not as well as I would have liked) that were not well covered in this book. The areas that could definitely use more attention were CIDR-based sub-netting and physical facility equipment and tools. There was a lot of emphasis on troubleshooting scenarios as well. While the book (content/quizzes/test) focuses many questions around Microsoft tools/utilities, I experienced next to no Microsoft-centric questions on the actual test. (The test is actually very vendor neutral)
I realize it is not easy to create a test prep book like this, and I appreciate authors like Glen providing these resources. But at the same time, it is hard for any book to provide all possible knowledge needed for a test like this.

Network+ Certification Study Guide, Third Edition (Certification Study Guides) Review

Average Reviews:

(More customer reviews)I am an Associate professor at a community college and have been teaching Network+ for more than 10 years. After the recent certification exam change I had to review what was out there for the new exam. I am so glad this book was one I decided to take a look at. The book is to the point... check out the number of pages out there in some of the other study guides. Glen has a practical down-to-earth style of writing that makes it easier for students to get a handle on new concepts. The review questions at the end of the chapter are really good. I also love how the book has hands-on labs right in the chapters, and if that is not enough there is a whole lab manual that comes on the cd. Finally, if all this isn't enough there is a practice exam that comes on the cd as well. Wow, quite a bit for the money.
With that said there are a couple minor tweaks that need to be made in the next edition.
1. The requirements listed for the Network+ exam in the intro are for the old exam.
2. I would like to have seen "N10-004" or "Network+ 2009 exam" somewhere on the front or back cover. I had to look at the publishing date to make sure I had the
right book for the new exam.
3. The practice exam that came on the cd is good but there is no way to control what chapters or exam domains you want to pull questions from.
With that said, I am looking forward to using this book over the next few years and will be the first in line for the 5th Edition.
