# Intro to Web Architecture

The purpose of this module is to provide a mental model of how web sites work, some of the key terminology and how these concepts relating to the coming modules on the course.

You'll be introduced to lots of new concepts in this module, and it's not important to *remember* or *deeply understand* everything that's covered. What's important is you understand that they exist and how they fit together. You'll learn a lot more about how they work throughout the rest of the course.
