The frontend communicates with the backend primarily through HTTP requests over the network. Here’s how it typically works:

1. Request/Response Model:
   The frontend (client-side) sends requests to the backend (server-side) asking for data or services. The backend processes these requests, interacts with databases or other services, and sends back responses.

2. APIs (Application Programming Interfaces):
   Communication usually happens via APIs, most commonly RESTful APIs or GraphQL APIs. The frontend calls endpoints (URLs) exposed by the backend.

3. Common HTTP Methods:

• GET: Fetch data (e.g., user info, posts)

• POST: Send new data (e.g., form submissions)

• PUT/PATCH: Update existing data

• DELETE: Remove data

4. Data Format:
   Data is often exchanged in JSON format because it’s lightweight and easy to parse in JavaScript.

5. AJAX and Fetch:
   Frontends use technologies like AJAX (Asynchronous JavaScript and XML) or the modern Fetch API to make asynchronous requests without reloading the page.

6. Web Sockets:
   For real-time communication (chat apps, live updates), frontends may use WebSockets, which allow two-way interactive communication.

7. Authentication:
   Requests often include authentication tokens (e.g., JWT, cookies) to verify user identity.

The backend responds with JSON data that the frontend uses to update the UI.

In summary, the frontend and backend interact via network requests, exchanging data through well-defined APIs to build dynamic, interactive applications.
