Ok, here goes...
Usenet is the network of machines that send and receive Usenet newsgroups.
Some of these machines use the Internet to connect to the rest of Usenet,
others use UUCP protocol to connect to the rest of the Usenet.
UUnet is a non-profit corporation founded to enhance connectivity. They sell
access to the Usenet via UUCP. They also (as AlterNet) sell access to the
Internet, and to Usenet via the Internet. Usenet is something they sell
access to, not "a component" of their company.
Usenet uses more of the Internet's traffic capacity than any other use, but
it is not a component of the Internet, it is a use for it. Also, almost none
of the Usenet traffic that goes over the Internet uses UUCP for the crossing;
most of it uses a protocol called NNTP (network news transport protocol).
