## What is a data structure? What are the types of data structures?

Data structures are used to store data in a computer in an organized fashion. Different types of data structures are:-

Stack- Works in first in last out order. The element inserted first in stack is removed last.

Queue- First in First out order. The element inserted first is removed first.

Linked list- Stored data in a linear fashion.

Trees- Stores data in a non linear fashion with one root node and sub nodes.

## What is a data structure? What are the types of data structures?

The scheme of organizing related information is known as ‘data structure’.

The types of data structure are:
Lists: A group of similar items with connectivity to the previous or/and next data items.
Arrays: A set of homogeneous values
Records: A set of fields, where each field consists of data belongs to one data type.
Trees: A data structure where the data is organized in a hierarchical structure. This type of data structure follows the sorted order of insertion, deletion and modification of data items.
Tables: Data is persisted in the form of rows and columns. These are similar to records, where the result or manipulation of data is reflected for the whole table.
