Mehta Textiles Ltd. wants its employees to access the company website using the name www.mehtatextiles.example rather than a numeric address. A server that stores records linking this name to the website's IP address is queried whenever an employee types the name. Under the Domain Name System, what is the main function performed in this process?

DNS translates a human-readable domain name into the numeric IP address of the server hosting the site, so the browser can reach it. It does not encrypt traffic, allocate device addresses, or filter packets; those are done by TLS, DHCP and firewalls.
