- **FRONTEND**: What user sees and interacts with.
- **BACKEND**: Logic, processing, authentication, APIs, etc.
- **DATABASE**: Stores and manages data.

### 3. How a Website Works?
A web application works on a simple request-response cycle.

1. **CLIENT** (Browser) sends a **Request**
2. **SERVER** processes it and returns a **Response** (HTML, Data)
3. **DATABASE** stores/retrieves information

### 4. Client -> Server -> Database Flow

- **1. User / Browser**: User opens the website.
- **2. Internet**: Request is sent over the internet.
- **3. Web Server**: Server processes the request.
- **4. Database**: Server fetches / saves data in the database.
- **5. Response**: Server sends the response back to the browser.
