Final answer:
c. DNS, The DNS service provides IP addresses to correspond to fully-qualified domain names upon network request.
Step-by-step explanation:
The DNS (Domain Name System) service provides IP addresses to correspond to fully-qualified domain names upon network request. It translates human-readable domain names like www.example.com into IP addresses like 192.0.2.1, which are required for communication on the internet.
DNS works by maintaining a distributed database that maps domain names to IP addresses. When a user requests the IP address of a domain name, DNS servers handle the query and return the corresponding IP address.
For example, suppose a user wants to access a website by typing its domain name in a web browser. The browser sends a DNS request to a DNS server, which then responds with the IP address associated with the domain name. The browser can then establish a connection to that IP address and load the website.
