What is Data Structure?

A data structure is a way of organizing and storing data in a computer so that it can be accessed and used efficiently. It refers to the logical or mathematical representation of data, as well as the implementation in a computer program.

Classification:

Data structures can be classified into two broad categories:

• Linear Data Structure: A data structure in which data elements are arranged sequentially or linearly, where each element is attached to its previous and next adjacent elements, is called a linear data structure. Examples are array, stack, queue, etc.
• Non-linear Data Structure: Data structures where data elements are not placed sequentially or linearly are called non-linear data structures. Examples are trees and graphs.

Applications of Data Structures:

Data structures are used in a wide range of computer programs and applications, including:

• Databases: Data structures are used to organize and store data in a database, allowing for efficient retrieval and manipulation.
• Operating systems: Data structures are used in the design and implementation of operating systems to manage system resources, such as memory and files.
• Computer graphics: Data structures are used to represent geometric shapes and other graphical elements in computer graphics applications.
• Artificial intelligence: Data structures are used to represent knowledge and information in artificial intelligence systems.

Advantages of Data Structures:

The use of data structures provides several advantages, including:

• Efficiency: Data structures allow for efficient storage and retrieval of data, which is important in applications where performance is critical.
• Flexibility: Data structures provide a flexible way to organize and store data, allowing for easy modification and manipulation.
• Reusability: Data structures can be used in multiple programs and applications, reducing the need for redundant code.
• Maintainability: Well-designed data structures can make programs easier to understand, modify, and maintain over time.
