DTO == Data Transfer Object, i.e. a class that encapsulates the properties of a particular object (Value Objects are just another name for the same thing).
DAO == Data Access Object, i.e. a class that encapsulates access to data.
Make sense?

Well, rather than I write a long answer explaining these (since there are countless resources on the internet that already do this - have a google to find them), why don't you explain what it is about them that you don't understand? If that is just a basic "what are they?" question I'd recommend searching the internet first.
