What is the role of a web browser?

The role of a web browser is fundamentally to allow users to access and navigate the Internet. A web browser acts as a user interface that retrieves, presents, and navigates information on the World Wide Web. It interprets HTML, CSS, and JavaScript to display web pages, making it possible for users to view and interact with content ranging from simple text and images to complex web applications.

Web browsers facilitate various online activities, such as searching for information, visiting websites, and streaming media, thereby serving as a critical tool for Internet functionality. The primary function of a browser is to simplify the process of finding and displaying information, enabling users to explore the vast resources available on the web effectively.

The other options describe functionalities that are not the direct role of a web browser. For instance, developing websites requires web development skills and tools, not a browser; creating security protocols is typically handled by cybersecurity professionals and software, while managing offline data storage is a separate function related to data management rather than browsing the web.
