Final answer:
The DNS server is used to translate domain names to IP addresses.
Step-by-step explanation:
The network device used to translate a domain name to the associated IP address is the DNS server. The DNS (Domain Name System) server is responsible for resolving human-friendly domain names into the corresponding IP addresses that computers and networks use to communicate.
For example, when you type a website address (e.g., www.example.com) into your web browser, the DNS server translates that domain name into the IP address of the server hosting the website. This allows your computer to establish a connection and fetch the requested web page.
