Introduction

The terms "Internet" and "World Wide Web (WWW)" are often used synonymously. But there is a significant difference between these terms. As you learned in the first lesson, the WWW is based on the Internet. That means that the Internet was developed before the WWW and therefore is independent of the WWW. The WWW on the other hand is dependent on the Internet, because it uses the Internet.

Visualisation of the various routes through a portion of the Internet (Wikipedia)

We will deepen these statements in the next chapters. First we will concentrate on the term "Internet" and afterwards, in unit 2, we explain the characteristics of the World Wide Web.
