DHCP helps in automatic IP address configuration
DNS helps in resolving domain names to IP addresses

Accepted Answer

DHCP is a network protocol used to automatically assign IP addresses, subnet masks, default gateways, DNS server addresses, and other network configuration parameters to devices on a network.
When a device (such as a computer or smartphone) connects to a network, it sends a DHCP request broadcast message to the network. A DHCP server then responds to the request, offering configuration information and assigning an available IP address from a pool of addresses.
DHCP operates on a client-server model, where DHCP servers manage and distribute IP addresses, while DHCP clients (devices) request and receive configuration information.
DHCP simplifies network administration by centralizing the management of IP address allocation and eliminating the need for manual configuration of devices.
DNS (Domain Name System):

DNS is a hierarchical distributed naming system used to translate human-readable domain names (such as www.example.com) into numerical IP addresses (such as 192.0.2.1) that are used to locate resources on the internet.
DNS serves as the internet's "phone book," mapping domain names to IP addresses and vice versa. It allows users to access websites, send emails, and perform other network activities using easy-to-remember domain names instead of complex IP addresses.
DNS operates through a distributed network of DNS servers organized in a hierarchical structure. These servers include authoritative DNS servers, which store and manage DNS records for specific domains, and recursive DNS servers, which help resolve domain names by querying authoritative DNS servers on behalf of clients.
