What is the main function of web browsers?

The main function of web browsers is to retrieve, present, and navigate information on the World Wide Web. This involves fetching data from various web servers, rendering the content (like text, images, and videos) so that users can view it, and enabling the user to interact with different web pages by navigating back and forth or through links. Browsers interpret HTML, CSS, and JavaScript, which are the core technologies used to create websites, allowing users to experience the content as intended.

While searching the internet for information is a feature that users commonly associate with browsers, it is not the primary function of the browser itself. Instead, that action is executed through a search engine, which can be accessed via the browser. Generating website content refers to web development tools or platforms, not the browser's function. Lastly, blocking unwanted ads is a feature that certain browsers or browser extensions may offer, but it does not represent the central purpose of a web browser. Thus, the primary role of a web browser remains the retrieval, presentation, and navigation of web content.
