What is DNS an acronym for in technology?

The acronym DNS stands for Domain Name System. This is a crucial component of the internet that translates human-readable domain names, like www.example.com, into numerical IP addresses, which computers use to identify each other on the network. The Domain Name System serves as a directory for the internet, enabling users to access websites by name instead of having to remember complex numerical IP addresses.

The functioning of DNS is vital for the smooth operation of web services. When a user enters a website address in a browser, DNS servers work to resolve that address to the correct IP address so that the browser can locate and connect to the desired web server.

The other options do not correctly define DNS: Data Network System and Direct Name Service do not reflect established terminology used in networking, while Digital Network Security pertains more to protecting a network from threats, rather than the naming and addressing aspect of the internet that DNS handles.
