    What is a Data Structure?

    • A data structure is a way to organize and store data in a computer so that it can be efficiently accessed, modified, and manipulated.
    • It is a collection of data elements, each having its own value and characteristics, and relationships between each element.

    Relationship between Data Structures and Abstract Data Types (ADT)

    • An Abstract Data Type (ADT) is a high-level description of a data type that specifies how the data type can be used without caring about how it is implemented.
    • A data structure is an implementation of an ADT, providing a concrete representation of the data type.
    • In other words, an ADT defines the interface, and a data structure provides the implementation.

    Why Different Applications Use Different Types of Data Structures

    • Different applications have different requirements, such as speed, memory usage, and functionality, which dictate the choice of data structure.
    • Each data structure has its own strengths and weaknesses, making some more suitable for certain applications than others.
    • For example, a database application might use a B-tree index for fast search and retrieval, while a web browser might use a hash table for efficient caching.
