## How the Web Works
A simple web page is rendered on the screen via the following steps
> There are many sub steps in this process
> but these are the highlights
1. You instruct the browser which webpage you'd like to see
2. The browser looks up the site in a 'DNS Server'
- This is like a big phone book for website server addresses
3. The browser asks the server to send over a specific page of the website `developer.mozilla.org/filename.html` or `developer.mozilla.org`
- If asked for a 'root' level address, most servers will return `'root'/index.html`
4. The server sends the HTML file back to the browser
5. The browser starts to read the HTML file from the top to the bottom, \*stopping any time that additional resources are required
- CSS stylesheets
- JavaScript files
- Fonts
- Images
6. Browser makes requests for additional resources
- Those resources might request even more files
7. Once the browser gets to the bottom of the page it can start rendering, and then load the page
