Data structures are essential components in computer science, serving as organized formats to store, manage, and manipulate data efficiently. They enable the effective implementation of algorithms and facilitate operations such as data retrieval, insertion, deletion, and modification.

Common data structures include arrays, linked lists, stacks, queues, trees, and graphs, each with unique characteristics and use cases. Arrays provide indexed access to elements but have fixed sizes, while linked lists offer dynamic memory usage with efficient insertions and deletions.

Stacks and queues operate on LIFO (Last-In-First-Out) and FIFO (First-In-First-Out) principles, respectively, and are used in various applications like expression evaluation and task scheduling. Trees, such as binary trees and heaps, represent hierarchical data and support fast search and sort operations.

Graphs model complex relationships between data points and are essential in network analysis, pathfinding, and numerous other fields. Choosing the appropriate data structure is critical for optimizing performance and resource utilization in software development and problem-solving.
