What is the World Wide Web?

The World Wide Web is non-linear. There is no top, there is no bottom. Non-linear means you do not have to follow a hierarchical path to information resources.

You can jump from one link (resource) to another:

to a second resource to a third resource

You can go directly to a resource if you know the Uniform Resource Locator (URL) (its address):

You can even jump to specific parts of a document.
