I am begining to work on a webhosting glossary....does anyway have some recommendations on some sites to look at for ideas?

for technical stuff go here:

For basic TCPIP stuff and "how the net works 101" head to:

http://www.ipprimer.com/index.cfm

BIND stuff:

http://www.ccs.neu.edu/groups/systems/proj/DNS/bog.html

BIND to djbdns:

http://flounder.net/djbdns/bind-to-djbdns.html

apache:

http://httpd.apache.org/docs/

bash scripting:

http://www.tldp.org/LDP/abs/html/

...that is all on the more technical side. There is a business side to webhosting, revenue, margins, etc. He can pick up a high school economics book and breeze through that in a few days.

After html, learn xhtml/css/php

try - http://www.pugmarks.net/glssry.asp

Its a good one.
