Module 5
How Apps Work
Behind the screens: frontend, backend, databases, and how apps talk to each other
Module Overview
Every time you open an app on your phone or load a website in your browser, you are interacting with a complex system that spans multiple computers, programming languages, and databases. The app you see is just the tip of the iceberg — underneath lies a world of servers, APIs, and data flows.
This module pulls back the curtain on modern applications. From the user interface you interact with (frontend) to the business logic running on servers (backend) and the databases that store everything — you will understand how apps really work.
In this module, students will learn:
- What an app is made of — frontend, backend, database
- How the frontend and backend communicate
- What APIs are and how they power apps
- How databases store and retrieve data
- How HTTP, REST, and web technologies work
- How authentication keeps apps secure
- How apps are deployed to the cloud
- The future of apps with AI
