I like John Quarterman's Matrix definition, which comprises all
interconnected networks that can send electronic mail to each other
(eg Internet, BITNET, FIDO, UUCP, Xwhatever).
I think it was Dave Herron (spelling?) who defined an internet as a
network connected by means of the TCP/IP protocol. The Internet is
just one of those :-)-O
All Internet services indeed require the user to have a (unique) IP
number. If you dial into a service provider you are allocated the
number associated with the modem or rather dialin port you access. If
you are behind a firewall you have a unique number within your LAN
which is then translated by the firewall (proxy) into another number.
BTW, It is quite telling, if someone says: "I want Internet, not just
e-mail" in particular if this person lives in a developing country.
What does it tell us? The person has been reading books, newspapers,
magazines, watches TV or is listening to (USAID :-)-O) consultants,
but that person most likely does not *NEED* access at all. People
that *NEED* access use email and find ways to do it. To wit Healthnet,
WWW is just the icing on the cake. And it is highly overrated. And
the few resources that are actually useful can be accessed by WWW
That notwithstanding the fact that full Internet connectivity is what
we should be (and some of us are :-)-O) working for.
