30 Back-end Web Development Quiz Questions and Answers

Back-end web development refers to the process of building and maintaining the server-side components of a website or web application. It involves working with databases, server logic, and APIs (Application Programming Interfaces) to ensure that the website or web application functions correctly, stores and retrieves data, and communicates with the front-end (client-side) interface.

In a typical web development scenario, the front-end is responsible for the user interface, design, and user interactions that users see and interact with directly in their web browsers. On the other hand, the back-end handles the behind-the-scenes functionality that powers the website or application, such as processing user inputs, managing databases, and serving content to the front-end.
