Understanding DNS DNS is a critical component of the internet infrastructure that allows users to access websites using human-readable domain names instead of numeric IP addresses. The abbreviation DNS stands for Domain Name System. Why is DNS Important? It translates domain names (like www.example.com) into IP addresses (like 192.0.2.1) that computers use to identify each other on the network. It simplifies the web browsing experience, allowing users to remember easily understandable names instead of complex numeric addresses. DNS helps with load balancing, redundancy, and ensures that users can reach their preferred websites quickly and efficiently. Explanation of Other Options Domain Name Server: This term refers to servers that are part of the DNS system but does not represent the entire system itself. Data Name System: This is a non-standard term that is not used in the context of computer networking. Data Number System: This refers to numerical representations in computing but is unrelated to DNS. Conclusion In summary, the correct option for DNS is Domain Name System, reflecting its function and purpose within the networking framework.
