What are Data Structures?

Data structures are ways of organizing and storing data so that it can be accessed and modified efficiently. They are essential for designing efficient algorithms and for solving complex problems.

Why Use Data Structures?

• They help manage and organize data effectively. They allow for efficient data retrieval and manipulation. Different structures are used based on the needs of the application, like fast lookups, sorting, or dynamic resizing.

Types of Data Structures

• Primitive Data Structures: Basic types like integers, floats, and characters. Non-Primitive Data Structures: More complex types such as arrays, lists, stacks, queues, trees, and graphs.

Example

• Imagine a library. If you need to find a book, it's easier if books are organized in a catalog (data structure) rather than scattered randomly.

Activity

• Draw a diagram of different data structures and explain their uses in real-life scenarios, such as how a library catalog is similar to an array or a queue.
