Please explain the differences between DNS, DHCP and Active Directory?

Answer 1

DNS = Domain Name System
DHCP = Dynamic Host Configuation Protocol
Active Directory = Microsoft's proprietary LDAP (Lightweight Directory Access Protocol)

As for differences, they all handle a different role in network services but without a context for your question, I am inclined to think this is a homework question so I'll leave the research up to you using the links below.

Answer 2

DNS resolves hostnames to IP addresses,

DHCP configures host IP addrss, gateway and other network settings (including DNS).

Active Directory is Microsoft's LDAP directory services used primarily in Windows environments. Used for authentication, authorization and managing network objects.

Differences are many, these are apples and oranges you might say.
