Upgrading and Repairing PCs (19th Edition) Review

Average Reviews:

(More customer reviews)Great reference covering the most recent technologies. I've been following the series since the 3rd edition and each one has been worth its weight in gold! If only Amazon knew, I would be willing to pay in excess of $200.00 for this! ;D My personal last edition was the 13th, so this will make a fine addition to the library.
I love how Scott covers the history, and even though there have been complaints on earlier editions of this inclusion of past technologies, it is valuable information.
This edition was a Christmas gift to my brother who is now getting into computer repair. After a few days, he is eating the book up alive! Amazon was great in its shipment and technically was not going to release it until a couple of days before Christmas, however they not only made an earlier release date but got it to me before Christmas. I'll be purchasing a copy for my self after this review!
If your in doubt as whether to purchase this, don't be. This is a very inexpensive way to add to your understanding, what could take you "forever" in your Google searches!

Computer Networks (5th Edition) Review

Average Reviews:

(More customer reviews)The book maintain the classic structure of subjects based on the OSI model (which is good and proven to work for those who learn about networking)...you will notice the author has updated contents in several sections of the book: from entire new paragraphs, going trough the examples to the jokes itself, adapting them to the modern context in which we live.
New interesting topics as RFID and 3g-4g cellular networks are also commented in good detail...I would say not "mile wide, inch deep", but "mile wide, two inches deep"
I do not give them 5 stars because the problems and exercises at the end of each chapter do not have the solution (or at least the correct answer)...why not sharing the information once and for all???...

Data and Computer Communications (9th Edition) Review

Average Reviews:

(More customer reviews)For the stated audience -- academics and self-study professionals -- it is hard to envision a better single volume study of datacom principles. Divided into five primary parts (overview, data communications, WANs, LANs, and Networking Protocols), it can provide excellent first course source material to provide a general overview of datacom principles and techniques.
Note that, with as much information as being presented, the book is much more useful as a course text for study than for casual reading. However, it covers sufficient areas to be useful as a reference for the data & computer communications professional. Additional information is maintained by the author on his web site which provides more up-to-date information than can ever be maintained in a printed volume.

Computer Networks, Fifth Edition: A Systems Approach (The Morgan Kaufmann Series in Networking) Review

Average Reviews:

(More customer reviews)A few months ago, I needed to quickly re-educate myself about Weighted Fair Queueing (WFQ). I have a bunch of networking texts on my bookshelf, but I automatically reached for the first edition of Peterson & Davie. I got what I needed: a clear, thorough, yet self-contained discussion. I even got a little extra from the text, which pointed me at other related topics and raised some open problems.
It's true that several of those other books cover WFQ, but I've learned over the last few years that I might as well start with Peterson & Davie, because I usually end up there. They cover almost all of the interesting topics in computer networks, and at just the right level of depth for a quick introduction or refresher. (The authors wrote this as a textbook, and I don't doubt that it would also be an excellent foundation for a graduate level course.) I'm glad to see the second edition, because they've included new material, as well as expanding some of the existing coverage.
This is not the book for exhaustive and definitive coverage of every network protocol; to get a fuller story, readers should turn to the concise list of references cited at the end of each chapter. (In fact, I found at least one mistake in their coverage of HTTP, an example that simply won't work, which is repeated in exercise 24 of chapter 9 -- some students might find this confusing.) But into a book that one can actually lift, Peterson and Davie have crammed a remarkable breadth and depth of detail, written with a clarity often missing from the primary source material.

CompTIA Network+ Study Guide: Exam N10-004 Review

Average Reviews:

(More customer reviews)I bought Todd Lammle's book and found it to be instrumental to me for passing the test. I compared his test questions against other test questions and found other tests to be using outdated questions. Some of his questions could have come directly from the Net + test, they were that close.
I found his lesson layout to be helpful, teaching you the various basics you need to know. Then building off of them to take you to the next level. There is some critical things you need to memorize and Todd tells you what you need to remember. You might not know why at the time, but you'll be glad you took the time to memorize the lists, by the next chapter or two.
I found for me, the best study technique was to sit with the book and a stack of index cards. I would make flash cards as I read each chapter. I did every exercise and worked every practice test. I would start each day retaking the previous chapter's test, to help me remember what I learned the day before. Then, I would read the next chapter, while making flash cards. Then I would do the labs and take the post chapter test. Anything I missed, I would go back and study that relevant section until I realized what I got wrong and why.
My only beef with the book is that some of the test questions got the answers wrong, they should have been better proofed. But then again, being able to tell what the correct answer was and knowing what's a wrong answer, is a testament to how good the training is.
After 3 weeks of study, I took the Net + exam. I finished the exam in less than 30 minutes, and did not even go back and review any questions. I passed the exam with 875 points out of a possible 900. I'd say that shows how good the training actually is.

WiMax Explained; System Fundamentals Review

Average Reviews:

(More customer reviews)I needed to get up to speed on WiMax and quick. I bought a few books but this one was clearly the best. It's a straight forward "explaination" of WiMax starting with "What is WiMax" to Service Flows.
It starts with technical information that I already understood and clearly added/combined/modified technical details to develop a logical and technical explaination of what WiMax. It's at the right technical level. It stops short of all the protocol details (however many of those are existing and I know them) that bogs down a lot of technical books. There's nothing worse than pay $50 for a book and getting 20 pages of overview and then 150 of standards which I could have gotten for free online.
This book definately gave me the right technical information sprinkled with illustrations that were SIMPLE to understand. The figures are clear and relate directly to the explainations. It saved me a lot of time by getting me up to speed quick so I now have a good understanding of the WiMax system.
One more praise for this book...The index is really well done. I'm not sure what it is, but when referring back to this book for information when I'm working, I find it easily in the index. They must be doing something right. Most technical books have me just flipping through the book to find information becuase the index doesn't help get you to the specific item you need.

This book explains the functional parts of a WiMax system and its basic operation. You will learn how WiMax can use base stations to provide high speed data connections that can be used for voice, data and video services to distances of over 30 km. The original WiMax system was designed to operate at 10-66 GHz and it had to change to offer broadband wireless access (BWA) in the 2-11 GHz frequency range. To do this, the WiMax standard includes variants (profiles) that use different combinations of radio channel types (single carrier -vs- multicarrier), modulation types, channel coding types to provide fixed, nomadic or portable services.WiMax can provide multiple types of services to the same user with different QoS levels. For example, it is possible to install a single WiMax transceiver in an office building and provide real time telephone services and best effort Internet browsing services on the same WiMax connection. To do this, WiMax was designed to mix contention based (competitive access) and contention free (polled access) to provide services which have different quality of service (QoS) levels. You will learn about WiMax protocols and how they are designed to allow for point to point (PTP), point to multipoint (PMP) and mesh networks. Operators can use the mesh configuration to allow it to link base stations without the need to install or lease interconnecting communication lines. Some of the services WiMax operators can provide include leased line, residential broadband, commercial broadband and digital television (IPTV) services.WiMax can use radio channel bandwidths that can vary from 1.25 MHz to 28 MHz and data transmission rates can exceed 155 Mbps. The types of data connections on WiMax radio channels include basic (physical connection), primary (device control), secondary (configuration) and transport (user data).You will learn about the typical range for WIMAX systems and how to extend the range of WIMAX systems through the use of directional antennas. Some of the most important topics featured include:. The Functional Parts of WiMax Systems. Basic WiMax Operation. The Types of WIMAX Services. Data Transmission Rates. WIMAX Industry Standards. WIMAX Technology Evolution. Protocols Used in WiMax. Physical and Logical Channel Types. The Different Types of WIMAX Devices. Basic Security Operation
