Kurzbeschreibung

Frustrated with networking books so chock-full of acronyms that your brain goes into sleep mode? Head First Networking's unique, visually rich format provides a task-based approach to computer networking that makes it easy to get your brain engaged. You'll learn the concepts by tying them to on-the-job tasks, blending practice and theory in a way that only Head First can.

With this book, you'll learn skills through a variety of genuine scenarios, from fixing a malfunctioning office network to planning a network for a high-technology haunted house. You'll learn exactly what you need to know, rather than a laundry list of acronyms and diagrams. This book will help you:

  • Master the functionality, protocols, and packets that make up real-world networking
  • Learn networking concepts through examples in the field
  • Tackle tasks such as planning and diagramming networks, running cables, and configuring network devices such as routers and switches
  • Monitor networks for performance and problems, and learn troubleshooting techniques
  • Practice what you've learned with nearly one hundred exercises, questions, sample problems, and projects

Head First's popular format is proven to stimulate learning and retention by engaging you with images, puzzles, stories, and more. Whether you're a network professional with a CCNA/CCNP or a student taking your first college networking course, Head First Networking will help you become a network guru.

Synopsis

Frustrated by reading networking books chock full of acronyms that put your brain into sleep mode? Head First Networking is your companion on your step-by-step journey from a newly minted CCNA/CCNP, to a network guru with not only the answers but the explanations to support them. "Head First Networking" provides a task-based approach to the computer networking body of knowledge. This is a practical title that teaches networking concepts as tied to on-the-job tasks, blending practice and theory in a way that only Head First can. For example, the task of running wires or cables on the surface can be explained to a network newbie as: run Cable A for Purpose B between locations 1 and 2. However Head First Networking uses this opportunity to "go deeper" and discuss the types of signals being transmitted "over the wire", and how signal loss impacts a network, explains the significance of the differences between hardware for connecting hosts and devices in a network, and finally starts delving into the topics of network models and network topologies (or why you set up a network in a specific fashion).

Like all of the books in the Head First series, "Head First Networking" uses a visually rich format designed for the way the brain works. Based on the latest research in neurobiology, cognitive science, and learning theory, this book combines words and pictures in a compelling, mixed-media style that not only helps readers understand a subject, but also to remember it.

4.0 von 5 Sternen Guter Einstieg für Azubis im Bereich Fachinformatiker 6. November 2010
Von NAKD
Format:Taschenbuch
Sehr anschauliche Darstellungen, viele Aufgaben - leider mit teils groben Fehlern.

Nur die englische Version ist brauchbar, die deutsche Übersetzung ist so schlecht, dass ich dem Verlag empfehle ein paar Kröten mehr für fähige Übersetzer auszugeben und die erste Auflage der deutschen Fassung zu recyceln.

Alles in allem ein sehr guter Einstieg für Azubis im Bereich Systemintegration.

4.0 von 5 Sternen Recht unterhaltsame Einführung 12. April 2010
Von Udo Reb
Format:Taschenbuch|Verifizierter Kauf
Das Buch fängt praktisch bei Null an und geht doch so in die Tiefe, dass man seinen eigenen Traffic analysieren kann. Leider machen die Autoren einige Fehler, aber das tut der Sache keinen großen Abbruch.

Ich habe wenig Nutzen aus diesem Buch bekommen. Der Inhalt ist einfach zu flach und geht nicht in Detail. Für Anfänger sinnvoll, aber wer mehr wissen will ist unterfordert. Eins brachte mir die englische Ausgabe. Sie ist in unterhaltsamen, einfachen Englisch geschrieben und zum Lernen dieser Sprache bestens geeignet.

2.0 von 5 Sternen disappointing and frustrating 24. August 2009
Von apophenier - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I wanted to like this, but I think that it fails to cover its subject, fails to be useful for most people, and needs more careful editing. Overall, the book presents the networking material very slowly, but confusingly. The cute examples are distracting and often fail to illustrate the topics.
It spends many pages on basic undergrad comp sci mechanics that are neither necessary nor useful in building and maintaining a network, and rarely in troubleshooting network problems.
The text and exercises refer to material that has not been presented yet. I often had to look ahead a few pages to find a definition. A couple of the solutions appear to be wrong, or are not explained enough to understand.
Several times, the book suggests that something is possible, but does not tell how to do it. Often the discussion is limited to Cisco specifics and fails to address other equipment that a new networker might encounter.
Suggestions for improvement:
- thorough editing
- a straightforward summary at the end of each chapter
- an appendix of the common maintenance and diagnostic tools
I look forward to a second edition.

3.0 von 5 Sternen Doesn't really explain much networking! 18. Juli 2009
Von Tarah Tamayo - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I hold a CCNP and work in Network Engineering. Recently I managed to take a look at a copy of this book. It's a good introduction to physical connections, though perhaps too much of the book is spent on this topic. It falls flat on anything you might want to do with your network connected up, though.

This book discusses the CCNA (Cisco Certified Network Associate) a few times. While it might be a good introduction if you're thinking of going into the CCNA having never worked on a network before, it is not a CCNA, or even pre-CCNA book. It is a good overview of the physical layer.

My major issues with this book are: the old technologies and glossing over of upper layer network functions. In terms of technology, there's a fairly long section on coaxial network connections (10Base2). While you might come across it in "the field," it's a fairly esoteric technology now. Furthermore, the router shown in the book is so old that CCNA-goers don't even buy them for practice anymore! I have a feeling the IT prof that wrote this book has never actually configured a router (at least not in the last 20 years).

The router image is actually confusing because of its age (and the error in the diagram doesn't help). It shows a Cisco 2500 series router (OLD) with two "fast ethernet (feth)" ports. Unfortunately the arrows to the ethernet ports are actually going to "Serial" ports (as you can just barely make out on the router). This is confusing because the Console port actually does look like what most know as an ethernet port. The actual ethernet connections on this router are an old style AUI port (not described in this diagram). The take-away of this is that it's entirely confusing to the beginner.

The book barely discusses switching and routing. The descriptions are good, and some of the lower-level switching layer is described well. There is no discussion about how switches communicate to each other - I don't think switching loops (an important CCNA-level concept) are even mentioned. TCP/IP (how packets are used to talk from computer to computer) is described, but also oversimplified.

The routing protocol described (RIP) is old technology, though still useful, but it's over simplified. The difference between "Distance Vector" and "link-state" protocols is not described (nor do those terms show up in this book). Worst of all, they point you in the direction of the RFCs if you want to learn more about common protocols like OSPF and BGP! These highly technical references might be useful if you're already an engineer, but are probably the worst possible reference for a beginner.

Summing up, buy this book if you've never seen or used a network before. If you're starting your first job as a tech or interning for a network engineer, this might be a good intro. If you're looking for CCNA resources, you're probably already well past this book. I would not have been pleased had I purchased this book even before I started working toward my CCNA.

1.0 von 5 Sternen Not of much value 21. August 2009
Von BillyJoeBob - Veröffentlicht auf Amazon.com
Format:Taschenbuch|Verifizierter Kauf
I really cannot imagine who would benefit from reading this book. Hardly a worthy addition to O'Reilly's Head First lineup, it offers only the simplest introduction to the world of networking. I doubt that the authors, who are apparently instructors at a college on a reservation in Montana, were a wise choice to author this volume - 20 years to complete a degree? and a liberal arts instructor?

There are a few errors and apparent misunderstandings in the text. More seriously, much of the material is simplified to the point where the information content is at danger of disappearing altogether. The chapters on physical cable layout are particularly pointless, containing such insights as (and I paraphrase here): "if the AC ducts are in the way, reroute your cables". OK... thanks - I was going to cut right through them!

Little effort is made to provide useful references for further reading; only the networking RFCs are suggested. This is completely unhelpful, and suggests that the authors themselves are unfamiliar with the (abundant) literature on TCP/IP, routing, switching and network security.

With this volume, and some of the more recent Head First titles, O'Reilly risks returning to its previous bad practice of publishing ANYTHING which they think will make money. I very much hope they rethink their approach to what has, until recently, been a remarkably useful series.

3.0 von 5 Sternen Book needs revisions and edits 11. Mai 2011
Von Frank Grimes - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I read to this book to gain an overview and survey of networking. I know more than most people when it comes to computers, but I certainly wouldn't consider myself an expert. I like computers. I've taken some college classes on them and I seem to have an aptitude for them. I set up my home network, but that was the extent of my practical experience. I've been considering formally studying "Network Administration," so I read this book to gain an introduction.

The book says it's for people who "need to learn networking for a job, for a class (like CCNA), or just because you think it's about time you learned the difference between a switch and a router". So this book seemed like it would be a good fit for me.

To briefly cover the book's contents, the chapter subjects include 1) Fixing Physical Networks, 2)Planning Network Layouts, 3) Tools and Troubleshooting 4) Packet Analysis 5)Network Devices and Traffic 6)Connecting Networks with Routers 7)Routing Protocols 8)The Domain Name System 9)Monitoring and Troubleshooting 10) Wireless Networking 11)Network Security 12)Designing Networks. The topics are covered over 500 black and white pages.

I'll start out with the things I enjoyed with this book.

-The book is aesthetically pleasing. In the 500 pages, I would guess about half of the book is white space and pictures. The pictures are either goofy people or computer parts. It makes the book more digestible and approachable. I believe this is the standard style for the "Head First" series.

-The book is not boring. It's designed as a learning tool as opposed to a reference book. It explains concepts while asking the reader to do written exercises on every couple pages. The exercises go along with a silly story. For example, in chapter 1, you are helping "Coconut Airways" fix their network. Problems keep arising as the story progresses so you learn more and more about what is wrong.

-The book explains concepts creatively. For example, one reoccurring feature is an interview or conversation between two pieces of networking hardware or software. It helps emphasize their functions and differences.

Stuff I don't like:

-Many of the exercises in the book are faulty. It wasn't uncommon to come to an exercise page and not have an idea what is being asked. They often asked questions about material that was not even mentioned yet. For example, on page 309, you are to match various acronyms with their functions. How am I supposed to know what "SOA", "CNAME" or "IN" do if they weren't even referred to before the exercises?

-I must have run into at least five typos throughout the book. For example, on page 174, "connection" is spelled "connetion". On page 231, it reads "The can also" instead of "They can also". On another page, "You're" is spelled "your". One typo in a published book may be acceptable, but many really undermine its credibility. I certainly wasn't looking for errors. If I'm the one who caught these simple errors, how do I know the technical details are correct?

-I'm not sure I read much, if anything, on the OSI model. Before this book, I didn't know much about networking, but I know everyone who has taken a networking class knows about the OSI model. It's the very important theoretical basis of networking. But it's not even in the book's index. It makes me wonder what other vital information was left out?

-The writing is often cleaver and fun, but it is too often unclear. I know it's tough to explain technical concepts, but I would guess 1/3 of the book left me scratching my head for clarification. I often had to supplement the pages by looking up terms or context on the internet. Too often, unreasonable assumptions were made about the reader's knowledge.

In Conclusion:

Throughout reading the book, I frequently got the impression that this book was a draft that was rushed to print. This book is in its first edition and it shows. It should have been more thoroughly reviewed by its target audience before being sent to production. At the same time, I don't regret reading this book. After all, I did learn a great deal. I just had to constantly supplement and fact check the book with other resources to make sense of it all.

I suggest you take its faults into consideration before reading the first edition of Head First Networking.

2.0 von 5 Sternen Not worth $10 9. Mai 2011
Von Matthew E Glosson - Veröffentlicht auf Amazon.com
Format:Taschenbuch
I hold a Cisco CCNP/CCDP and was looking for a basic book to help some people I know who want to break into the world of networking. I was able to get the book here in India for about $10 US. I should have heeded the negative reviews more, because even if it was free, it's a time-waster.

As has been mentioned, the authors, and for that matter, the technical reviewers, are not networking professionals. Perhaps they have dabbled in it (they obviously have), but how long ago? This does not have any up-to-date information, it is more like a history of networking, and an incomplete one at that. Perhaps if your goal was to become a cable installer and have a little insight into what the guys who aren't climbing ladders are up to, this would be a book to read.

The worst thing, the thing that made me want to write a review here, is that the glowing quotes on the back of the book that describe how wonderful it is, are written by the technical reviewers! One would think that must violate some fair advertising law.

The book, perhaps like all titles in the "Head First" series, tries way too hard to be amusing. It also tries too hard to be simple. It says in the beginning that it is refreshing to have a networking book that doesn't delve into the OSI model. Well, sorry guys, the OSI model might not be sexy, but it is critical to real networking.

The book is not Cisco-specific, most of the time, which is fine. However, I also purchased another book at the same time as this one that is Cisco-specific. It doesn't have all sorts of goofy pictures of people doing yoga, but it is amusing and has real-world things in it that aren't sugar-coated. It is the CCENT/CCNA ICND1 Official Exam Certification Guide, 2nd Edition by Wendell Odom. Even if you were wanting a general non-Cisco-specific overview of networking, I would still recommend that book way ahead of Head First Networking.
