Domain Name Services (DNS) is a system that translates human-friendly domain names, like www.example.com, into numerical IP addresses that computers use to identify each other on the internet. This process allows users to access websites easily without needing to remember complex strings of numbers. When you type a website's name into your browser, DNS servers quickly look up the corresponding IP address and direct your request to the correct server. This essential service ensures that internet navigation is smooth and efficient, enabling seamless communication between users and websites.
