What is the role of a web browser?

The role of a web browser is fundamentally to retrieve and navigate information on the World Wide Web. A web browser acts as an interface that allows users to access, display, and interact with content available on the internet, including websites, videos, images, and other resources. It interprets HTML, CSS, and JavaScript to render web pages correctly for the user, facilitating seamless exploration and interaction with online content.

Web browsers provide functionalities like bookmarks, history, and tabs, which enhance the user experience when searching for and organizing information. They also support various web protocols and standards that enable secure and efficient communication between the client (the browser) and server.

The other options do not accurately describe the primary function of a web browser. Creating online databases requires specialized software or services for database management. Editing photos and images is the role of graphic design software, while managing system updates pertains to operating system functionality focused on keeping software up to date, not a web browser's purpose.
