A data structure is a format for organizing, processing, retrieving and storing data so it can be easily accessed and effectively used.

Definition : 

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.

Importance of linear data structures :

• Structured data is quantitative while unstructured data is qualitative.
• Structured data is stored in data warehouses while unstructured data is contained in data lakes.
• Structured data can be immediately analyzed while unstructured data requires processing and transformation.
• Structured data follows predefined formats while unstructured data comes in many different formats.

APPLICATIONS OF DATA STRUCTURES :

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.
