Core Principles of Abstract Data Types (ADTs)

High-Level Description

An ADT (Abstract Data Type) describes:
1. What operations can be performed.
2. Not necessarily how they are implemented.
Separates the logical view (concepts and operations) from the implementation (data structures, code).

Example

Stack (push/pop), Queue (enqueue/dequeue), Set (union/intersection).

Purpose of ADTs

Provide a blueprint for data handling.
Allow programmers to work with consistent interfaces while underlying implementation can change.
