What is the purpose of the Domain Name System (DNS) in computer networks and the internet?
The Domain Name System (DNS) plays a crucial role in computer networks and the internet by providing a hierarchical naming system that translates human-readable domain names into IP addresses. This translation is essential for the proper functioning of network communication, as it allows users to access resources on the internet using familiar and meaningful domain
