What is this "web" of which I speak?

I've been throwing the term "web" around from the get-go, so what do I mean by it?

I think I came closest to a definition in the post on Deutsch's "Fallacies of Distributed Computing": the web is all resources accessible on the net. That's maybe a little more inclusive than the usual formulations, but I think it's a good target to shoot for.

Now all we have to do is figure out what a "resource" is and what "the net" is, and we're golden.
