What is Backend?

Backend development refers to the server-side of web or app development, focusing on how a system works behind the scenes to process user requests and manage data. It involves creating and maintaining the technology responsible for databases, servers, and application logic. Backend developers use programming languages like Node.js, Python, Java, Ruby, or Go, along with frameworks such as Express, Django, Flask, or Spring Boot. The process includes setting up APIs, managing database interactions, ensuring application security, and optimizing performance. Backend development is essential for handling authentication, data storage, real-time functionality, and seamless communication with the frontend.
