Persistent and temporary objects - confused in terminology

Here is my definition of two terms, although I'm not sure if it is complete:

A persistent object is an instance of a class in a domain model that represents some information retrieved from a database. a transition object is an instance of a class in a domain model that is created in memory

a) I assume that the terms persistent and transient are used only for objects in the domain model, but not also for business-level objects that live outside the domain model?

b) Do we also use two terms for data transfer objects?

c) Are these two expressions used for Value objects?

thank
