and why?

It seem abstract in that it is and idea created and implemented with nodes arranged a certain way.

But it did not show up in the text here:




they are referred to as data structure b.c. other ADTs can be created from them.

In this train of thought, can I assume that SLLs and DLLs are data structures as well.

Is is not so black and white, perhaps more of a spectrum of classification?

A binary search tree is a data structure. The interface it supports (the list of operations you can perform on it and their semantics) is an abstract data type.

See https://en.wikipedia.org/wiki/Abstract_data_type for explanation of the difference between an ADT and a data structure.
