Tutorials about Internet

[modric]

I'm looking for some really good simple but extensive Internet tutorial, which covers all aspects of internet: connections, search engines, mails, FTP.

I've found so far:

Learnthenet
Internettutorials

Someone can start here on Wikipedia. Great, hyperlinked article which virtually doesn't end.

Please don't post here just any piece of tutorial, I'm only looking for one which covers as many possible topics (Internet exclusively, NOT graphic or other programs or PC hardware).
