When the web browser fetches data from an internet connected server, it uses a piece of software called a rendering engine to translate that data into text and images. This data is written in Hypertext Markup Language (HTML) and web browsers read this code to create what we see, hear and experience on the internet.

A web browser is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones.

Web browsers serve as the software gateway through which users can access the internet and request/receive information. Billions of people around the world use web browsers in order to access the internet, with Google Chrome, Safari, Internet Explorer, and Firefox being some of the most popular browser options.
