Linear data fashion- Linked list is an example of linear data storage or structure. Linked list stores data in an organized a linear fashion. They store data in the form of a list.

**Non Linear data structure-** Tree data structure is an example of a non linear data structure. A tree has one node called as root node that is the starting point that holds data and links to other nodes.

### Define a linear and non linear data structure.

**Linear data structure:** A linear data structure traverses the data elements sequentially, in which only one data element can directly be reached. **Ex**: Arrays, Linked Lists

**Non-Linear data structure:** Every data item is attached to several other data items in a way that is specific for reflecting relationships. The data items are not arranged in a sequential structure. **Ex**: Trees, Graphs

Linear data structure is a structure wherein data elements are adjacent to each other. Examples of linear data structure include arrays, linked lists, stacks and queues. On the other hand, non-linear data structure is a structure wherein each data element can connect to more than two adjacent data elements. Examples of non linear data structure include trees and graphs
