A: You know, I am a bit confused about the relationship between the Internet and World Wide Web. Whenever I think of the Internet, the first thing I think about is the World Wide Web. Do they refer to the same thing?
B: The two terms are often used interchangeably, but they are not actually the same.
A: Could you tell us the exact definitions of the two terms?
