The internet is the global network of networks, and the www is the world wide web.

Even though they are used to refer to the same thing, they are not. The internet is the connection between computers anywhere in the world, the www is the collection of information that can be accessed through the internet.

The www is a service that is built on top of the internet infrastructure. The internet is hardware based because it is the infrastructure meaning it is the connection between the computers and servers. The www is like the software that works through the internet to share information.
