What is an abstract data type?

In A Level Computer Science, an abstract data type (ADT) is a logical description of a data structure that specifies the operations that can be performed on it, without detailing its implementation. Common ADTs include stacks, queues, linked lists, and trees.

Why are ADTs important?

ADTs allow programmers to focus on functionality rather than internal workings, promoting modular and reusable code.
