What is the role of a web browser?

The role of a web browser is fundamentally to access and display content on the World Wide Web. When you use a web browser, you enter a URL or navigate to a website, and the browser retrieves the necessary data from web servers. It interprets HTML, CSS, and JavaScript code to render the content you see on web pages, allowing you to navigate through text, images, videos, and interactive elements seamlessly.

While creating and designing websites is an important task, that function is typically performed using specialized web development tools or software rather than the browser itself. Similarly, maintaining server databases is a distinct role typically associated with database management systems and server-side applications rather than browsers, which focus solely on client-side content. As for sending emails and messages, that's primarily the function of email clients and messaging applications, not web browsers.

Thus, the primary purpose of a web browser is to serve as an interface for users to access, view, and interact with web content efficiently.
