Since we seem to be getting pedantic...

There's "The (capital I) Internet" - which, most date to the flag day, 
and the "Public Internet" (the Internet after policies changed and 
allowed commercial & public use over the NSFnet backbone - in 1992f, as 
I recall).

Then there's the more general notion of "internetworking" - of which 
there was a considerable amount of experimental work going on, in 
parallel with TCP/IP.  And of (small i) "internets" - essentially any 
Catenet style network-of-networks.

In theory, there is no difference between theory and practice.
In practice, there is.  .... Yogi Berra

Theory is when you know everything but nothing works.
Practice is when everything works but no one knows why.
In our lab, theory and practice are combined:
nothing works and no one knows why.  ... unknown
