Types of Data Structures
Data structures are an integral part of computer science and are essential for solving complex problems efficiently. They are used to store and organize data in a particular way, making it easier to access and manipulate. In this section, we will discuss the most common types of data structures that you need to know for the A-Levels on Cambridge International exam boards.Arrays:
Arrays are a collection of elements of the same data type, stored in a contiguous memory location.They are used to store and retrieve data quickly, making them one of the most basic and widely used data structures.
Linked Lists:
Linked lists are a linear data structure where each element is connected to the next using pointers. They can be singly or doubly linked, allowing for efficient insertion and deletion operations.Stacks:
Stacks follow the Last In First Out (LIFO) principle and are used to store data in a particular order. The topmost element is always the first one to be removed from the stack.Queues:
Queues follow the First In First Out (FIFO) principle and are used to store data in a specific order. The first element added to the queue is always the first one to be removed.Trees:
Trees are hierarchical data structures that consist of nodes connected by edges.They are used to represent relationships between data and are widely used in database systems and file systems.
Graphs:
Graphs are non-linear data structures that consist of vertices and edges. They are used to represent networks and relationships between objects, making them useful for modeling real-world systems.Real-World Applications
