What is the role of a web browser?

The role of a web browser is fundamentally about retrieving and displaying web content. A web browser acts as a client-side application that interacts with web servers to fetch HTML documents, images, stylesheets, and other resources. When you enter a URL or click on a link, the browser sends a request to the server where the site is hosted. Once the server responds with the necessary files, the browser interprets this data, rendering the web page on your screen in a format that is visually comprehensible to users. This process includes interpreting HTML, CSS, and potentially JavaScript to provide a complete and interactive user experience on the web.

In contrast, options that suggest running backend scripts, managing databases, or creating web content pertain to different roles typically handled by web servers, database management systems, or web development tools, rather than the main function of a web browser itself. A web browser's primary focus is on the user's interaction with content, emphasizing retrieval and display.
