I can't just let this remark go by and go to bet. :-) The Internet is a
network of computers (actually a network of networks of computers), on
which computers can name and reach each other (using IP addresses or
domain names) and communicate for various purposes. The internet is the
foundation for a lot of services, one of which is the World Wide Web.
The WWW is a set of documents that can be given a globally valid name (a
URL), and these names can be used by software such as a browser to
retrieve said documents using certain standardised ways of communication
over the internet (HTTP, the hypertext transfer protocol, is the web's
"native" way of asking a server for a document). Other things you do
over the internet are not part of the WWW even if some users do them
with the same software. Reading UMRA can be done with web software such
as Mozilla Suite or Opera, or indeed through websites such as Google
Groups, but newsgroups predate the web and use a different model of
internet communication. Email is a similar example. Peer-to-peer
filesharing uses the internet but is another different form of internet
communication. Then there are things that computers do over the internet
which you hardly observe, such as synchronizing the clock, or indeed the
underlying activities that drive the internet itself, such as converting
a web server's domain name (www.bbc.co.uk) into a numerical IP address,
or routing your request for a BBC web page from your computer to the BBC
web server. I've gone on a bit, but I hope I've made you see how the
internet is so much more than the web. Good night. :-)
