Very rarely does a book come along that changes the way you view the world. Before reading Mr. Smythes book all I didn't know a Network Relay from a Catalytic Converter. But now that I've read this book, I'm a new man. Not only did I bawl my eyes out at the OSI transition, laugh until my belly ached at the hilarious Router sequence, but by the time Colin's Final thoughts rolled around, I was already designing a Token Ring Bridge Transistor that the kid's love. Spellbinding! A Ripping Read!
