DNS is the Domain Name System is one of the most important services in many IP-based networks. Its main task is to answer inquiries about name resolution. The DNS works much like a telephone directory inquiry.Dynamic DNS, DDNS or DynDNS is a technique for dynamically updating domains in the Domain Name System. The purpose is that a computer automatically and quickly changes the associated domain entry after changing its IP address.

Check e.g. Wiki, you find al info you need
 
DNS is what allows devices and browsers to translate a human readable address into an IP address which for a lot of people is more difficult to remember. Without DNS, typing in google.com is going to get you no where.

Dynamic DNS is a method that lets you automatically attempt to update name servers and remain up-to-date with IP address changes in or nearly in real-time.

DNS is in most cases an absolute must, whereas DDNS is not required but will be nice to have if your project has the need.
