I see the loop and understand that. Does wordpress interpret the url to set up what is on the page?

For example, if you have a custom post type called books, you can create a specific template to handle single book posts rather than using the default index.php.
This would be a good read - WordPress Template Hierarchy
I have always found the infographic on this page really helpful and even have it as bookmark to this day. WordPress Template Hierarchy Infographic.
Hope this is what you are looking for.

The simple answer to that is - a mySQL Database.
WordPress takes the fields you fill in within the admin area of a post or page and stores that data in the database ready to be retrieved on request. When it is stored in the database it has an ID is given to that post. The post ID is the source of all things great!
To have a dive into things, get a local install set up and navigate your way into phpMyAdmin, take a look through the database structure, this is what WordPress queries and retrieves the content from that you created in the admin area. You really want to have a look at the wp_posts table, this will give you a good insight into have things get stored and then how they can be queried and retrieved.
I hope this is more in line with what you are looking for.

Then it pulls in the content you create in the WSYISYG editor. So it's a permalink that differentiates pages to WordPress. :-)

3,658 PointsSorry. I guess I'm not being clear with my question.
Yup. I understand the wordpress hierarchy so that's not my question. Yup. I understand that a permalink differentiates the pages.
Getting closer with the statement here: "Then it pulls in the content you create in the WSYISYG editor."
What I'm asking is what does wordpress DO with the permalink - HOW does it know what "content" to pull into the page. ie; I can see a permalink here: http://localhost/treehouse-theme/?page_id=6 This is a post or page with an id of 6. How does it "translate" the permalink into knowing what content to put on the page that is called? What is running inside WP that goes and finds the content associated with page_id of 6?

Treehouse Moderator 91,252 PointsI'm afraid the answer to that is way beyond my expertise. Someone else may be able to help you but just know that the team at WordPress use PHP to build the framework and allow us to create content. If you want to look further at the code you can download your installation to localhost (if you haven't done so already and look all the individual files in the folders wp_content, wp_admin and wp_includes.
Good luck.
