[Air-l] Internet vs. WWW

[Laurent Straskraba]

Hi,

it's rather simple:

1) There is the Internet, the "big" inter-connection of networks and any 
item being connected to it.
2) The Extranet, which means all networks which are not part of an internal 
network
3) The Intranet, this is the one you're using within a specific location 
(office, etc.) - it's even protected (firewall, etc.)

You see, 2 and 3 are subgroups of 1.

Concerning the WWW, this is a *service*/application of the Internet, using 
the hypertext transfer protocol (http://) in order to enable access to 
text, pictures, sounds, and other combinations of multimedia by using webpages.

So if you're talking about WWW, you're still talking about the Internet but 
just by using one specific service. There are much more people are not so 
much aware of (newsgroups, ftp, wap, etc.).

If you'd like to read more about the WWW:

Best,
Laurent
