#Abstract Data Types

from wikipedia:

In computer science, an abstract data type (ADT) is a mathematical model for a certain class of data structures that have similar behavior; or for certain data types of one or more programming languages that have similar semantics. An abstract data type is defined indirectly, only by the operations that may be performed on it and by mathematical constraints on the effects (and possibly cost) of those operations.

Exact academic terms are arguable (see comments); I say 'data structure' or even 'abstract data type' and have no trouble being understood. 'Object' is more specific than what you asked for.

If you want total precision, say 'primitive' and 'non-primitive' (or 'secondary').

I'm wondering why this matters? What's the purpose?
