What is programming and its types


  what is computer programming  

Computer programming languages ​​allow us (users) to give instructions to the computer in a language that the computer understands.

Just as we humans have such a variety of human-based languages, in the same way there are many types of computer programming languages ​​so that they communicate with the computer. You probably also know that the part of the language that the computer understands is called binary“.

The conversion of programming language into binary is called “compiling”. All languages, whether it is C language or Python, all have their own distinct features, although they also have many commonalities with them.

These languages ​​allow computers to handle large processes and complex information quickly and efficiently.

  What is System Programming?  

System programming in hindi is called programming which is used for writing and designing computer programs. It allows computer hardware to be interfaced with the programmer and the user, while allowing the application to be executed effectively in a computer system.

System programming is used to develop computer system software that manages and controls computer operations.

Classification of Programming Languages
Therefore it is very important that you understand the classification of Basic Programming languages.

What is DBMS and what is its function
what is compiler
Programming languages ​​are broadly classified into three categories:


These languages ​​are closest to Computer Hardware. Every unique computer has a unique machine language. A machine language program is made up of a series of binary patterns (eg, 010011100) that represent simple operations that a computer can easily accomplish (for example, adding two operands, adding data to a memory location). move etc.).

Machine language programs are executable, which means that they can be easily run directly. If one wants to write a program in Machine Language, then he can do so, but for this the programmer will have to memorize many binary codes which is very difficult in favor of a human being.


The only purpose of bringing it was how to make programming easier for humans. In this machine language instructions have been replaced by the use of simple pneumonic abbreviations (eg, ADD, MOV). Therefore assembly languages ​​are also unique for a specific computer (machine).

In this, before execution, an assembly language program requires translation into machine language. This translation is accomplished by a computer program called Assembler. Assemblers are written for all unique machine languages.


High-level languages, such as C, C++, JAVA, etc., all appear to be English-like, so they become easier for programmers to “think” according to the programming language. Translation is required in high-level languages ​​only before execution in machine language.

This translation is accomplished either by a compiler or an interpreter. Compilers translate the complete source code before program execution. (Eg: C++, Java)

Interpreters translate source code programs one line at a time. (Eg: Python) Interpreters are more interactive than compilers.

A List of All Programming Languages

Different languages ​​have different purposes, so it is very important to know about all the different languages, let’s know about some types:-

1. Machine languages, they are directly interpreted by hardware.

2. Assembly languages, these are thin wrappers over a corresponding machine language.

3. High-level languages, all of them are machine-independent.

4. System languages, they are designed to write low-level tasks, such as memory and process management.

5. Scripting languages, these are generally extremely high-level and powerful.

6. Domain-specific languages, used only in highly special-purpose areas

7. Visual languages, these are non-text based languages.

8. Esoteric languages, they are not for use but they are very interesting, funny, and educational in some directions.

These types are not mutually exclusive: Perl is both high-level and scripting; C is considered both high-level and system.

types of programming languages

If you want to look at the general in a basic way then there are two types of programming language:-

1. Low level
2. High level

Low level is called that which only the machine understands, these are minor, easy and fast conversions, because the computer understands these languages ​​(0 and 1). Assembly language which is low level, it can be easily converted into machine language with the help of assembler.

Whereas high level is called that which is understood by humans and it is written in English language, and the machine has to convert it into its own language. (C language is a high level language and it needs compilers for conversions)

By the way, the computer needs some functions to convert the high level language to the low level language, such as compiler, interpreter etc.

What is the Characteristics of Programming Language

Let us know about some characteristics of programming languages ​​which should be in a better programming language.

1. A programming language should be very simple, easy to learn and use, along with its good readability and easily recognizable by humans.

2. Abstraction should be an essential characteristic of any programming language, which should have the ability to define complex structure easily and also its degree of usability should be easy.

3. A portable programming language is always preferred by everyone.

4. The efficiency of programming language should be very high so that it can be easily converted into a machine code and also executed. Also it consumes less space in memory.

5. A programming language should always be well structured and documented so that it is more suitable in application development.

6. All the necessary tools, whether for development, debugging, testing, or maintenance of the program, should be provided to all through a programming language.

7. A programming language single environment called Integrated Development Environment (IDE) should be provided.

8. A programming language should be very consistent in terms of syntax and semantics.

Complete knowledge about computer programming

By the way, the list of programming languages ​​used right now is very long. But I have tried to give some information below in contact with all the important programming languages, so that you can first know what these programming languages ​​are, where they are useful and whether you should learn them or not.

I hope that you must have liked my article What is Computer Programming (What is Programming in Hindi). It has always been my endeavor to provide complete information to the readers about what programming is, so that they do not have to search any other sites or internet in the context of that article.
