What is the primary function of a web browser?

The primary function of a web browser is to read HTML documents. When you enter a URL or click on a hyperlink, the browser sends a request to the web server, retrieves the HTML document, and displays the content in a format that users can understand and interact with. Browsers interpret the HTML code, along with other web technologies like CSS and JavaScript, to render the page visually for the user. This interpretation capability is essential for enabling users to navigate the web seamlessly.

While executing server-side scripts, storing cookies, and managing databases are functionalities related to web applications and servers, they are not the main responsibility of a web browser itself. A browser's core role is to fetch, interpret, and display HTML documents and any associated resources.
