Is the 'means to access a resource' a resource in itself?

I think it's a matter of scope. When I manage a Web site I consider each
network card to be a resource, each HTTP server to be a resource, and each
HTML document to be a resource. When I look at services I take network cards
and HTTP servers for granted, but I still think of services as resources.
When I look at data I ignore the service.
