When I say for technical students i mean that this course and the the book are not suitable for the average student who had little or no technical background in computer technology. For those who are use to reading highly technical books with the all so common abbreviations such RAM, CISC, RISC, ROM etc., than this book will go into detail of the layers of network communication. It does not however, go into detail of certain layers(which will be covered in the following books) osi model, but give just enough to wet your appetite and opens your mind to how complex network technology can become. There are also, some wording issues and a few mistakes that aren't as unusual for any textbook out there though i have to say reading alone wont help you past the online examinations, for that you need to do labs and ask "what if..." and test it. While the text is more focused on understanding the concepts, the tests are more focused on troubleshooting, critical problemsolving/thinking, and analyzing scenarios.
