To explain how names are translated (resolved) into IP addresses, we need to understand the process of domain name resolution. Domain names are human-readable names used to identify websites, email servers, and other resources on the internet. On the other hand, IP addresses are numerical identifiers assigned to devices connected to a network.

The translation of names into IP addresses is done through the Domain Name System (DNS). The DNS is a distributed database that stores information about domain names and their corresponding IP addresses. Here is a step-by-step explanation of how this translation process occurs:

1. When you enter a domain name (e.g., www.example.com) into your web browser, your computer first checks its local DNS cache to see if it already has the corresponding IP address stored. The local DNS cache stores recently accessed domain names and their IP addresses to speed up future lookups.

2. If the IP address is not found in the local DNS cache, your computer sends a DNS query to a DNS resolver. The resolver is typically provided by your internet service provider (ISP) or a public DNS resolver like Google DNS or OpenDNS.

3. The DNS resolver receives the query and checks its own cache for the IP address. If the IP address is found, it is returned to your computer. Otherwise, the resolver proceeds to the next step.

4. The resolver acts as a middleman between your computer and the DNS hierarchy. It sends a recursive query to the root DNS servers, asking for the IP address associated with the domain name.

5. The root DNS servers respond to the resolver with a referral to the top-level domain (TLD) DNS servers. For example, if the domain name is www.example.com, the TLD DNS servers for the ".com" domain are queried.

6. The resolver then sends a query to the TLD DNS servers, asking for the IP address associated with the domain name.

7. The TLD DNS servers respond with a referral to the authoritative DNS servers for the specific domain. These authoritative DNS servers are responsible for storing the IP address information for the domain.

8. The resolver sends a query to the authoritative DNS servers, requesting the IP address for the domain name.

9. The authoritative DNS servers respond to the resolver with the IP address of the domain name.

10. The resolver caches the IP address and returns it to your computer.

11. Your computer now has the IP address and can establish a connection with the server hosting the website or resource associated with the domain name.

This process of name resolution happens behind the scenes and allows us to access websites and other resources on the internet using human-readable domain names instead of having to remember and enter numerical IP addresses.
