What is a Web Page?
A Web Page is a visual page on a web site that displays content of some kind. Content can be links to other Web Pages, images, a story, or any other kind of information that is considered valuable content to your audience.
Web Pages themselves only contain text, or more specifically HTML. This HTML is what allows a Browser to render a Web Page to make it meaningful and legible for someone to view.
What?! Can't Web Pages also contain images and files?
The answer is no. Web Pages 'appear' to have images and files (downloadable attachments) and the like, but they actually do not contain these items within themselves. Rather, Web Pages are just a collection of text and references to other items which may or may not be text.
For example, consider a Web Page which is a news story. This page might contain several paragraphs and a few pictures 'sprinkled' throughout the text. These images are referenced in the text. This reference is just a pointer that a web Browser can read which simply says: place an image at this location which is really located somewhere else (usaully in the same folder as the Web Page).
This allows multiple Web Pages to draw on the same resources within a web site.
