crash course on server setup and net interactivity

[smallfish]

hey guys,
i'm needing a (high-level) crash course in web server setup and how each part interacts with the next. for example:
dns server
registrar
hosting server
a records
etc

is there a good book or, better yet, source online?
thanks in advance,
grant

Those topics are more closely related to DNS than to HTTP (web servers).
