Which service translates domain names into IP addresses?

• A. DHCP
• B. DNS (Domain Name System)
• C. FTP
• D. HTTP

Answer: (B)

The service that translates domain names into IP addresses is the Domain Name System (DNS). When a user types a domain name, such as www.example.com, into a web browser, DNS servers resolve that human-readable address into a numerical IP address, which is necessary for locating and connecting to the server hosting the desired website. This process is essential for the functionality of the internet because, while humans find it easier to remember names, computers operate using numeric IP addresses. Other services mentioned do perform different functions. DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to devices on a network, FTP (File Transfer Protocol) allows for the transfer of files between computers, and HTTP (Hypertext Transfer Protocol) is the protocol used for transferring web pages. Each of these has distinct roles in network communication but does not involve translating domain names to IP addresses.
