Domain Name System
The Domain Name System (DNS) is an Internet service that serves as a directory or "phone book" for network communication. It translates human-readable domain names (such as example.com) into the numeric IP addresses required by host machines to locate and communicate with each other, eliminating the need for users to memorize numerical addresses.

What is the primary function of the Domain Name System (DNS)?
The Domain Name System (DNS) eliminates the need for users to memorize numerical IP addresses.
What everyday reference tool or directory is commonly used as an analogy to describe the function of the Domain Name System (DNS)?
Explain the role of the Domain Name System (DNS) in network communication, including what it translates and why this translation is necessary for both host machines and users.
Host machines can directly route network traffic to one another using human-readable domain names without translation into numeric IP addresses.
What specific type of identifier, exemplified by example.com, does the Domain Name System (DNS) translate into numeric IP addresses?
Which identifier do host machines require to locate and communicate with each other across a network?
The Domain Name System translates numeric IP addresses into domain names so host machines can locate one another.
What specific type of network offering or utility is the Domain Name System (DNS) defined as?
