There is the Internet and there are internets. The lowercase word internet(s) can be used for small, possibly isolated, networks which are interconnected using the internet protocol. They may or may not be connected to the world-wide Internet. A good example would be banks who network their automated teller machines to other bank networks. Another would be some university research networks.
The Internet with the capital I is the world-wide network of networks of which there is only one.
