Categorization of data can be stored in organized or linear form such as arrays and linked lists where data is arranged sequentially. Alternatively, data can be stored in non-linear or non-sequential structures like trees and graphs where the data is not arranged in a linear fashion. Examples of linear data structures are arrays and linked lists, while examples of non-linear structures are trees and graphs.

3. Categorization of data
In which we store the data in organized form or the
data store in the form of list.
Ex: Array, Linked list.
In which we store the data in non-linear structure or
the data is not arranged in sequential structure.
Ex: tree, graph
