Front-end, back-end, and full-stack development, these terms relate to different aspects of web development:

1. Front-End Development: This involves creating the user interface and user experience of a website or web application. Front-end developers work with HTML, CSS, and JavaScript to build the visual elements and interactivity that users interact with directly.

2. Back-End Development: Back-end development focuses on the server-side logic and database management of a web application. Back-end developers handle tasks like handling user data, server communication, and managing the application’s functionality behind the scenes. They often use languages like Python, Ruby, Java, PHP, and frameworks like Node.js.

3. Full-Stack Development: Full-stack developers are proficient in both front-end and back-end development. They have a broad understanding of how the entire web application works, from the user interface to the server infrastructure. Full-stack developers can work on both client-facing features and server-side functionality.
