What is the primary function of the DNS in web technology?

The primary function of the DNS, or Domain Name System, in web technology is to translate URLs into IP addresses. When a user types a web address or URL into a browser, the DNS takes that human-readable string and converts it into an IP address, which is the format that computers use to identify each other on the network. This process allows users to access websites without needing to remember complex numerical addresses.

For instance, when you enter 'www.example.com' in your browser, DNS helps your device locate the corresponding IP address, like '93.184.216.34'. This translation is crucial because, while URLs are convenient for users, the internet operates on IP addresses to route data efficiently between servers and devices.
