### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Short and Sweet, Useful and Neat
  

*by I***B on Reviewed in the United States on December 18, 2011*

I ordered this book for a class and I have really enjoyed each chapter this book had to offer.  I have learned a lot about Internet Computing.  This book gives a step-by-step, detailed explanation for how all parts of the internet works.  It has shown me lots that I didn't know and it has elaborated on the things I already knew something about.  Good buy.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good introductory book to the workings of the internet, BUT...
  

*by B***R on Reviewed in the United States on August 22, 2021*

Could use an update.  Things like 'How Blackberrys deliver email' should be dropped in favor of more relevant technology.  Something like, 'How Iphones deliver email' would be good, for starters.  And while there is an explanation for 'how online shopping works', why isn't there an explanation about how the underlying technology works?  For example, how does  HTTPS and SSL work?  Similarly, while there is a discussion on the FTP protocol, BUT, for the most part, simple FTP has fallen out of favor for more secure protocols, such as Secure FTP or SFTP.  Additional suggestions include - how 5g works, how cable modem/fiber and other broadband connections work and a comparison of all of the relevant broadband technology would be useful.  How apps work would also be a useful addition.To be fair, much of contents of this book is still relevant, the quality/production values are excellent, excellent graphics, it has good, introductory information. VPN, for example, is discussed, It contains good explanations on various threats, but here again, there are things that should be added/updated, such as a discussion on ransomware, for example.My advice would be that if you are looking for a good introduction to the workings of the internet, this is a pretty good, (but not great) choice and the contents/quality, as I've mentioned are rock solid, for its time.  Perhaps the author intends to release a revision, but for right now, it's likely that there are similar publications that are available that are more up to date than this one.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    and highly recommend it for middle-school level
  

*by D***D on Reviewed in the United States on January 28, 2015*

If you don't know anything about how the Internet works, read this book and you'll be an expert. It has pictures!!! The book is full of illustrations that almost anyone can understand. I used it to train my grandson, and highly recommend it for middle-school level. Maybe even late grade school! I don't know, those kids WOW me.
