They aren't the same thing: the Internet is a giant network connecting most of the computers in the world, and a set of methods for communicating among them.
The Web (the World Wide Web) is a giant collection of documents & applications—web pages—that are distributed using the Internet; these pages can talk about each other using hyperlinks.
So, what’s a network, then?
A network is simply a group of computers that are connected together so that they can talk to each other. The Internet is a massive one.
And a hyperlink...?
A hyperlink (usually called just a link) is a reference to another document. The reference is specific enough that the computer can automatically call up the referred-to document if the reader chooses to follow the link.
This concept of hyperlinks is the most fundamental idea behind the Web (and one which pre-dates it considerably).
Remind me of the difference between the Internet and the Web again
The Internet is the mass of wires, and the system used to send information through the wires; the Web is a corpus of pages.
You can send other things over the Internet besides web pages: emails, instant messages and streaming audio and video are good examples. The Internet came about in the 1960s; the Web in the 1990s (and it used the Internet to make all those pages available).
