A full stack application refers to a software application that is designed to run on both the front-end and back-end components. The term “full stack” refers to the entire range of technologies required to build and maintain the application.

Front-end development involves creating the user interface and user experience of the application. This includes designing and developing the visual elements that users interact with directly. Common front-end technologies include HTML, CSS, and JavaScript, along with various frameworks and libraries like React, Angular, or Vue.js.

Back-end development focuses on the server-side logic and functionality of the application. It includes handling data storage, processing, and managing user authentication and authorization. Popular back-end technologies include Node.js, Python (with frameworks like Django or Flask), Ruby on Rails, and Java.
