A Map associates a key (of certain type) with a value (of cerain type). The keys in the Map have to be unique; the values can be anything. Given a key a Map finds the associated value (if any). You can also delete associations from a Map. Certain Maps keep their keys in a certain order when you walk through the Map. That's all there is to it.
