Decoding the Stack: What's Inside?
Inside the stack's logo visually represents the three fundamental layers of any modern web application, all contained within the structure of code.
-
Presentation Layer
The Blue layer. This is everything a user sees and interacts with—the HTML, CSS, and JavaScript rendered by the browser.
-
Business Logic
The Green layer. This is the server-side code that handles requests, processes information, and determines what happens when you click a button.
-
Data Layer
The Yellow layer. This is where all the persistent information is stored, accessed, and managed—the foundational data that the application relies on.

Backend (Logic & Data)
The engine room of the web. Explore how servers process requests, manage databases, and communicate through APIs to deliver the content users see. We cover the core logic and architecture.
Understand Backend →DevOps (Deployment)
The practices that connect development and operations. Learn about continuous integration, deployment pipelines, cloud hosting, and containerization that get code reliably from your machine to the user.
Discover Deployment →How Does a Web App Talk to Itself?
Every click, request, and data load involves a conversation between the Client (your browser or app) and the Server. This is the fundamental cycle of the web.
- The Client sends a Request (e.g., loading a page).
- The Server processes the request (runs logic, checks data).
- The Server sends a Response (the HTML/Data/Images).
- The Client displays the result.
