This diagram covers Data Structures (Extension) within Data Types for GCSE Computer Science. Revise Data Types in 3.2 Programming for GCSE Computer Science with 19 exam-style questions and 10 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 4 of 9 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
Data Structures (Extension)
Stack and Queue: Stacks use LIFO (last in, first out). Queues use FIFO (first in, first out).
Linked List: Items are connected by pointers, so insertion and deletion can be efficient.
Binary Tree: A hierarchical structure where each node can have up to two children.
