When browsing the internet, a browser is an essential tool. A web browser is a software application that enables users to access and view websites on the World Wide Web. It allows users to search for information online, download files, watch videos, and communicate with other people over the Internet.

A web browser reads HTML documents sent from a server and then displays them as web pages on your computer or mobile device’s screen. Each website you visit will have its unique HTML code that tells your browser what kind of content it should display for you to view it properly. In addition, browsers can also read other types of data, such as images or multimedia files, to be displayed within pages.

Browsers come with different features depending on their type. Still, some common ones include bookmarks (for saving favorite sites), private browsing mode (which prevents certain activities from being recorded), and pop-up blockers (to avoid annoying ads). As technology advances, more features are added, such as tabbed windows allowing multiple websites open at once without having one page reloaded every time another is opened; this helps improve user experience overall when navigating around numerous pages quickly.

Overall, browsers provide convenient access to the vast online information today – making them an invaluable part of our lives!
