3. Classification of Data structure
The data structure are normally divided into two
categories—
Primitive Data structure
 Non- Primitive Data structure [ Derived]
Data Structure further classified into two categories :
Linear Data Structure
Non Linear Data Structure

5. Classification of Data structure
1) Primitive Data structure :
1. These are basic structures and directly operated upon by the
machine instructions.
2. A primitive data types defines how the data will be internally
represented stored and retrieve from the memory.
3. Eg: int, float, char, double.
2) Non- Primitive Data structure [ Derived] :
1. These are derived from the primitive data structures.
2. Eg: Array , Structure, Union, Pointer, User defined data types, linked-
list, stack, queue, tree, graph.

6. Linear Data Structures:
 The data structure where data items are organized
sequentially or linearly where data elements attached one
after another is called linear data structure.
 Data elements in a liner data structure are traversed one
after the other and only one element can be directly reached
while traversing.
 All the data items in linear data structure can be traversed in
single run.
 These kind of data structures are very easy to implement
because memory of computer is also organized in linear
fashion.
 Examples of linear data structures
are Arrays, Stack, Queue and Linked List.

9. Non Linear Data Structures:
 The data structure where data items are not organized
sequentially is called non linear data structure.
 In other words, A data elements of the non linear data
structure could be connected to more than one elements
to reflect a special relationship among them.
 All the data elements in non linear data structure can
not be traversed in single run.
 Examples of non linear data structures
are Trees and Graphs.

11. Difference Between Linear and Non Linear Data Structure
Linear Data Structure Non-Linear Data Structure
Every item is related to its previous
and next item.
Every item is attached with many other
items.
Data is arranged in linear sequence. Data is not arranged in sequence.
Data items can be traversed in a single
run.
Data can not be traversed in a single
run.
Examples: Array, Stack, Queue, Linked
List.
Examples: Tree, Graph.
Implementation is Easy. Implementation is Difficult.
