There are two types of data types in programming languages: primitive/system defined types and user defined types. Primitive types include integers and floats, while user defined types are created by programmers, such as classes and structures. Data structures organize data to allow for operations to be performed efficiently, and include linear structures like arrays which are accessed sequentially and non-linear structures like trees which allow non-sequential access. Abstract data types combine data structures with their operations and consist of the data representation and operations performed on that data.

2. • In computer science of programming we need something to hold our data and
a variable is something which comes in to the picture which do the same.

3. • A data type in programming language is set of data which already have a
predefined value(depending on the Programming language, System
specification)
Examples
• There are two kind of Data types in Programming language.
1. System defined data type Or Primitive data type.
2. User defined data type.

5. • Data types which are defined by the system are called or
.
• Primitive data type are provided by many language itself.
Examples :
The number of bits allocated to each data type is fully dependent on
Programming language, Compiler and the

7. • Data types which are defined by the user or Programmer are called .
• If the system defined data type is not enough for solving any problem then in most of the programming
language we create user defined data types.
Example : In we create structure , In we create Classes

9. • Data structure is a particular way to storing and organising data in to computer
so that we can perform operation on it and achieve our result in efficiently.
• General data structure includes :
• Depending on the organisation of the elements Data structure are divided in to
two types.

10. • In Linear data structure elements are going to be accessed in sequential order
but, it Is not compulsory that they are going to be store all element in sequential
order.

11. • In Non-Linear data structure elements are stored as well as accessed in non
linear way meaning each of the elements can be stored any where in computer
memory.
Example :

12. • All primitive data types (Int, float etc) support basic operation like addition,
multiplication, subtraction etc. The syste itself provides the implementation and
operation of primitive data types.
• For user defined data type we used to define the operation and implementation.
• To simplify the problem process of solving problem we combine data structure
with their operation and we call it .
• Abstract data type contains two part.
