"Makes learning easy" is written on the cover of this book. And Wendell Odom keeps this promise! And this is special - very special! (In fact lots of authors don't even care whether they make it easy to learn!) How does Wendell Odom reach his goal? He uses a language that is easy to read. He uses associations - e.g. he compares networks with pracel services (a technique that is recommended by every learing methodology). And Wendell Odom repeats the important concepts. So the book is easy to read, easy to understand and after you read it you really understand the concepts. I just hope that Wendell Odom will issue soon the book "second-step". I would immediately buy it!
