Back-end development involves server-side programming that powers websites and applications. It manages databases, server logic, authentication, and APIs to ensure smooth operation, security, and scalability. Back-end developers focus on processing user requests, handling business logic, and integrating external services.

How Back-End Development Works:
Back-end development supports the functionality and performance of applications. Key components include:

Server-Side Programming: Languages like Python, Node.js, Java, PHP, and Ruby process requests and execute logic.
Databases & Storage: MySQL, PostgreSQL, MongoDB, and other database systems store and retrieve data efficiently.
APIs (Application Programming Interfaces): RESTful and GraphQL APIs enable communication between the front-end and back-end.
Authentication & Security: Implements user authentication, encryption, and data protection measures.
Cloud & Server Management: Hosts applications on cloud platforms like AWS, Google Cloud, and Azure.
Back-end developers ensure data integrity, security, and seamless interactions between users and applications.
