DNS stands for domain name system. Its a library of all records & It resolves IP address to hostname (fqdn) or vice versa. DNS works on port 53 (tcp/udp). TCP for zone transfer & UDP for dns queries.

DHCP stands for dynamic host configuration protocol. It provides automatic IP address to clients.

This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
