[wplug] Intro to Web

[Weber, Larry A]

Does anyone know of a good intro book or website to understand the structure
of the Internet / WWW?  I am looking for something for middle/high school
aged kids that would explain how a message is routed from their computer to
a website and how data is sent back.  It should not be too technical
although a brief intro to http, tcp/ip formats would be good.  A good
glossary of terms would also help.
