Frontend:

- Technologies used: HTML, CSS, JavaScript, and frameworks like React, Angular, or Vue.js.
- Focuses on layout, design, and user experience (UX).
Backend:
- Refers to the server-side of an application, where data processing, storage, and business logic occur.
- Technologies used: Python, Java, PHP, Node.js, and databases like MySQL, PostgreSQL, MongoDB.
- Focuses on data management, security, and server-side logic.
Key Differences:
- Frontend: User-facing, handles presentation and interaction.
- Backend: Server-facing, handles data processing and logic.
Both frontend and backend work together to create a functional and dynamic web application.
