What Is a Web Browser?
A web browser is the software you use to access and view websites — Chrome, Safari, Firefox and Edge are the most common examples. It sends a request to a website's server, receives the underlying code back, and turns that code into the readable, clickable page you see on screen.
How Does It Turn Code Into a Webpage?
When you type a web address, the browser looks up the site's location, requests its files (HTML, CSS and JavaScript), and passes them to its rendering engine, which lays out the text, images and structure of the page. A separate JavaScript engine runs any interactive code — things like dropdown menus, forms and animations. Together, these engines are what turn raw code into the visual, interactive experience you actually see and use.
Tips for Browsing More Securely
Keep your browser updated, since updates frequently patch security vulnerabilities that attackers actively look for. Be cautious with browser extensions — only install ones from trusted sources, as malicious extensions can read everything you do online. Look for the padlock icon confirming a secure (HTTPS) connection before entering sensitive information, and consider using your browser's built-in tracking protection or a reputable ad blocker to reduce exposure to malicious ads. Clearing saved passwords and cookies periodically on shared or public computers also reduces the risk of your accounts being accessed by someone else.
