What is the primary function of DNS in networking?

The primary function of DNS (Domain Name System) in networking is to translate domain names into IP addresses. This process is essential because while humans find it easier to remember and use domain names (like www.example.com), computers and network devices require numerical IP addresses (such as 192.0.2.1) to identify each other on the network. When a user enters a domain name in a web browser, the DNS resolves that name to its corresponding IP address, allowing the browser to locate the correct server and load the desired webpage. This critical function enables seamless navigation of the internet, facilitating user access to websites and services without needing to memorize IP addresses.
