DataStructure

A data structure is a logical and systematic way of organizing, storing, and connecting data in memory so that it can be accessed, modified, and processed efficiently according to the needs of a program or problem.  

Simple Meaning

In simple words, a data structure decides:

• How data is arranged

• How data is stored

• How fast data can be used

Why Data Structures Matter

Without proper data structures:

• Programs become slow

• Searching and updating data becomes difficult

• Memory usage increases

With good data structures:

• Operations become faster

• Code becomes scalable

• Complex problems become easier to solve

Key Characteristics

A data structure focuses on:

• Organization of data

• Efficient access

• Data relationships

• Performance optimization (time & memory)
