    Correct Answer
    B. Domain Name Resolution
    Explanation
    Domain Name Resolution refers to the process of obtaining a corresponding IP address from a domain name. When a user enters a domain name in their web browser, the DNS (Domain Name System) server is responsible for resolving the domain name to its corresponding IP address. This is necessary because computers communicate using IP addresses, not domain names. The DNS server looks up the domain name in its database and returns the IP address associated with that domain name, allowing the user's device to establish a connection with the correct server.
