What does "client-server architecture" mean in REST?

Short answer: It means REST APIs separate the client (frontend/UI) and server (backend logic, database). The client is responsible for UI and user interactions. The server manages data, business logic, and security. This separation improves scalability and flexibility. 👉 Example: Client: React.js front-end making API calls. Server: ASP.NET Core Web API handling requests.

Real-world example (ShopNest)

Creating an order is POST /api/orders → 201 with Location header. Fetching is GET /api/orders/{id} → 200 or 404.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
