Frequently Asked Questions
What is a User-Agent string?
A User-Agent string is a line of text sent by your web browser in HTTP request headers. It tells web servers your browser application, rendering engine, version number, and operating system so the server can deliver the appropriate layout.
Why is keeping my web browser updated so important?
Browser updates patch critical cybersecurity vulnerabilities, improve JavaScript execution speed, support modern CSS and HTML standards, and protect you against malicious phishing exploits.
Can websites tell what operating system I am using?
Yes. Browsers transmit your operating system family (Windows, macOS, Linux, iOS, Android) through the navigator.userAgent and client hints APIs.
What is the difference between a browser and a search engine?
A browser (like Google Chrome or Apple Safari) is a software program on your device used to access and display websites. A search engine (like Google or Bing) is an online service accessible through a browser to find information across the web.
How do I clear my browser cache and cookies?
In Chrome, Edge, and Firefox, press Ctrl+Shift+Delete (Windows) or Cmd+Shift+Delete (Mac) to open the Clear Browsing Data dialog, select your time range, and confirm.
