Q:

Describe the functions of DNS and DHCP in the network?

Answer

Dynamic Host Configuration protocol (DHCP) provides network configuration information (including IP address) to hosts, eliminating the need to perform the configurations manually.


Domain Name Service  (DNS)resolves hostnames - both internet names such as www.routersim.com and device names such as workstation 2 to IP addresses, eliminating the need to know the IP address of a device for connection purposes.
