What is a web framework?

A web framework is a software framework that provides a foundational structure to support the development of web applications. It streamlines the process of building web applications by offering pre-designed components, tools, and libraries that developers can use to create dynamic websites more efficiently. This allows for the implementation of common functionalities, such as database integration, user authentication, and handling web requests, without the need to write all the code from scratch.

The correct choice highlights the essential role of web frameworks in modern web development, making it easier for developers to focus on building features and functionalities rather than getting bogged down by low-level programming tasks. In contrast to the other options, which refer to unrelated concepts such as graphical design tools, programming languages, or operating systems, the correct answer specifically addresses the core function and utility of a web framework in the context of web application development.
