A company secretary explains how a browser reaches a website by typing www.examplecorp.in. Which component translates this human-readable domain name into a numerical IP address?

The Domain Name System resolves a human-readable domain name such as www.examplecorp.in into the numerical IP address of the server. HTTP then carries the web request, SMTP handles email, and DHCP only assigns addresses to local devices.

Explanation

DNS works as the Internet's directory, resolving domain names into IP addresses so that browsers can locate servers. HTTP only carries the request and response once the address is known. SMTP is for sending email. DHCP assigns addresses to local devices and does not resolve public domain names.
