What is the primary function of a web browser?

The primary function of a web browser is to access and display content on the World Wide Web. When you use a web browser, it retrieves data from web servers and renders that data into a format that is visually interpretable for users. This involves translating HTML, CSS, and JavaScript code into the web pages that we see and interact with. Browsers are essential for navigating the web, allowing users to enter URLs, search for information, and view text, images, videos, and other web content.

The other options do not accurately reflect the main purpose of a web browser. While some browsers may offer features for storing data locally, this is a secondary capability and not their primary function. Creating and hosting websites is typically done through web development tools and platforms rather than the browsers themselves. Enhancing network security protocols is primarily the responsibility of security software and measures, not the browser's main objective.
