What does the acronym DNS stand for in network terminology?

Domain Name Service
Dynamic Network System
Data Network Service
Distributed Network System

The correct answer is: Domain Name Service

The acronym DNS stands for Domain Name System. This system is a fundamental component of the internet that translates human-friendly domain names (like www.example.com) into numerical IP addresses (like 192.0.2.1) that computers use to identify each other on the network. By resolving these domain names into IP addresses, DNS enables users to access websites easily without needing to remember complex numerical addresses. Understanding DNS is crucial for network administration and cybersecurity, as it plays a key role in network operations, such as browsing the web, sending emails, and connecting to various online services. The other options do not accurately describe DNS or its function in network infrastructure.
