It’s called full-stack because it covers all the layers (or “stacks”) of a web application — from the front-end user interface to the back-end server logic and the database.
Here’s a simple way to think about it:
- Front-end (client side): What the user sees and interacts with (like the webpage or app UI).
- Back-end (server side): The logic behind the scenes that handles requests, processes data, and controls the application’s behavior.
- Database: Where data is stored, retrieved, and managed.

When someone works with a full-stack technology or developer, they handle all these layers, not just one. So “full-stack” means the complete stack — the whole “cake” of components needed to build a full application, rather than just a slice.
For example, in the MEAN stack:
- Angular takes care of the front-end (UI and user interaction).
- Express + Node.js handle the back-end (server, APIs, business logic).
- MongoDB is the database layer (storing and managing data).

Because all these parts are included and work together, MEAN is called a full-stack solution.
So basically, “full-stack” = all layers of the software stack needed to create a complete app.
