This video also discusses the difference between static and dynamic IP addresses.

DHCP messages:
DHCPDiscover - Sent by client. Discover / find DHCP servers on the network.
DHCPOffer - Sent by server. Offering an IP address and other parameters for the client to use.
DHCPRequest - Sent by client. The client requests the address that was offered by the server.
DHCPACK - Sent by Server to acknowledge client. Contains information like IP address, lease time, default-gateway and other information.

You need to learn DHCP for your ccna and ccent exams. It is also important to understand the actual messages used and thus I am using wireshark in this video. You can also download the wireshark capture and check it out yourself.
