Question

Differentiate Concrete data type and abstract datatype?

Answer 1

Concrete data type:

1. A concrete data type is a data type whose representation is known.

2. Concrete data types or structures (CDT’s) are direct implementations of a relatively simple concept.

Abstract data type:

1. Abstract data type the representation of a data type is unknown.

2. Abstract Data Types (ADT’s) offer a high level view (and use) of a concept independent of its implementation.
