So do you know the difference between the Internet and the WWW? BT think that the terms are interchangeable, however, this is NOT the case.

The Internet is a interconnected network of networks. It is the physical network that all internet traffic must pass along.

The World Wide Web is a service that runs on the Internet. It is a series of documents hosted on Internet connected web servers that allow for  browsing using hyper links.

The two terms are not interchangeable in the exam and you will drop marks by using the wrong term.
