Full Node (GUI): This is an IRI (IOTA Reference Implementation) running and being accessed locally via a GUI. Any full node needs to be connected to neighbors via a static IP in order to function.
Headless Node: A full node running in your local console. It can be accessed via a simple UI called Nostalgia from a browser. It has the same requirements as a GUI full node, but alows to can open multiple Seeds (Accounts) at the same time.
