What is DNS (Domain Name System)

In this video, we explore how the Domain Name System (DNS) works to translate human-readable website names into machine-understandable IP addresses. The process is likened to a scenario where Ethan wants to call his Mom without knowing her phone number. The video illustrates how DNS queries, DNS resolvers, root servers, and authoritative DNS servers work together to find and provide the IP address for a given website. Just as Ann eventually finds and shares Ethan's Mom's phone number, the DNS eventually enables the browser to connect to the web server using the obtained IP address.
