1.

Define what an Abstract Data Type (ADT) is. Your answer should clearly explain the relationship between data and the operations performed on that data. Provide a simple example to illustrate your definition.

2.

Question 1: Define what an Abstract Data Type (ADT) is. Explain, using examples of a stack, a queue, and a linked list, why these data structures are considered ADTs. Specifically address the distinction between the what (the behaviour) and the how (the implementation) of an ADT.

3.

Question 2: Consider a stack ADT. Describe the key operations that are typically associated with a stack. Explain how each of these operations would be implemented using a linked list as the underlying data structure. Include a diagram illustrating the stack's state after performing a 'push' and a 'pop' operation.
