Which of the following best defines an abstract data type (ADT)?
- A data structure that specifies the details of the implementation in a particular programming language.
- A mathematical model of a data structure that specifies the type of data stored and the operations supported on the data. (correct)
- A data structure that stores objects and allows for the addition or removal of elements.
- A data structure that supports the Last-in First-out (LIFO) principle.

Study Notes
Abstract Data Types (ADT)
- An abstract data type is a data type defined by its behavior (operations) rather than its implementation.
- ADTs encapsulate data operations, allowing users to interact with the data without needing to understand the underlying complexity.
- Common examples of ADTs include stacks, queues, lists, and trees.
Stack Characteristics
- A stack is a collection of elements that follows the Last-in First-out (LIFO) principle.
- In LIFO, the last element added to the stack is the first one to be removed, akin to a stack of plates.
Stack Operations
- The operation to insert an element at the top of a stack is called Push.
- The operation that removes the top element from a stack is termed Pop.
Examples of ADTs
- Stacks are a specific example of an abstract data type discussed in various contexts, illustrating the concept of encapsulating functionality while managing data.
- Other examples of ADTs may include queues and linked lists, which share similar principles of abstraction.
