DNS stands for Domain Name System. It is a system that translates human-readable domain names into numerical IP addresses that computers can understand.

When you enter a domain name into your web browser, your computer sends a request to a DNS server to resolve the domain name into an IP address. The DNS server looks up the IP address associated with the domain name and sends it back to your computer. Your computer then uses the IP address to establish a connection with the web server hosting the website and retrieves the website content to display it to you.

DNS is an important part of how the internet works, as it allows users to access websites using easy-to-remember domain names rather than having to remember the numerical IP addresses of servers.
