Let’s say you’re using your Instagram application. Every time you refresh, new content is loaded on your screen. You can like a picture, add new ones, search for profiles and do so much more. Although it provides a seamless user experience, there’s a lot that goes on in the backend. HTTP requests are made to the Instagram servers to retrieve and load information. This is facilitated with the help of backend frameworks. Typically every application consists of the front-end, the backend, and the database. ➡️ About Post Graduate Program In Full Stack Web Development This program will give you the foundation for building full-stack web apps using the Java programming language.
