DNS (Domain Name System)

The Domain Name System (DNS) is like the internet's directory service. It translates human-friendly addresses (like www.example.com) into machine-readable IP addresses (such as 192.168.1.1) that computers use to locate each other online. When you type a website URL into your browser, DNS servers quickly find the corresponding IP address, allowing your device to connect to the right server and load the website. This system makes navigating the internet intuitive, so you don’t have to remember complex numbers—just familiar names.
