 Do you know what is computer programming ? It is a procedure by which instruction is provided to the computer to perform a task.

If you do not have any information about this, then I will say that you have come to the right place because today I am going to provide you all the information related to programming through the article What is Programming. That’s why I request you to read this article completely so that all your concepts will be clear.

To understand this properly, we have to understand programming languages ​​first because these languages ​​are the core of programming. We use these languages ​​and ask them to do some specific tasks. If seen, we use programming languages ​​for all the tasks of computers or any machines.

So today I thought why don’t you guys know what is a programming language and its types? Complete information should be provided about it so that it is easy for you to understand this topic. So without delay let’s start and know what is programming.

What is Computer Programming

The usage of computer programming languages enables us (users) to communicate with computers in a language they can understand.

There are many different computer programming languages available in order to communicate with computers, just as there are many different human-based languages used by humans. You undoubtedly already know that “binary” refers to the portion of a language that a machine can understand.

“Compiling” is the process of converting a programming language into binary. Despite having many things in common, all languages, including Python and C, each have their own unique characteristics.

These languages make it possible for computers to process complicated data and large-scale processes fast and effectively.

What is System Programming?

Programming, often known as system programming, is the process of creating and developing computer programmes. It enables successful application execution in a computer system while enabling computer hardware to connect with the programmer and the user.

Software for managing and controlling computer activities is created using system programming.

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:


The closest languages to computer hardware are these ones. Each computer has its own machine language. In a machine language program, simple processes that a computer may readily do are represented by a series of binary patterns (like 010011100). (for example, adding two operands, or adding data to a memory location). moving, etc.


Programs written in machine language are executable, making it simple to run them immediately. One can develop programs in machine language if they are desired, but doing so requires the programmer to learn several binary codes, which are exceedingly challenging for a person to do.


It was simply introduced to see how to make programming simpler for people. Simple pneumonic acronyms have taken the place of machine language and instructions in this (eg, ADD, MOV). As a result, assembly languages are specialized to a particular computer.

An assembly language program must be translated into machine language before it can be executed in this. An assembler is computer software that does this translation. For every distinct machine language, assemblers are created.


High-level languages make it simpler for programmers to “think” in accordance with the programming language because they all seem to be English-like, including C, C++, JAVA, etc. Only prior to execution in machine language is the translation in high-level languages necessary.

An interpreter or a compiler can carry out this translation. Before a program is run, compilers convert the entire source code. (Ex: Java, C++)

One line at a time, interpreters translate programs written in source code. Compilers are less interactive than interpreters, such as Python.

A List of All Programming Languages

Different languages ​​have different purposes, so it is very important to know about all 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 , are designed to write low-level tasks, such as memory and process management.

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

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

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

8.   Esoteric languages , 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 refers to something which only a machine understands; these transformations are minimal, simple, and quick because a computer can understand these languages (0 and 1). Low-level assembly language is easily translated into machine language with the aid of an assembler.

High level, on the other hand, is defined as what can be comprehended by humans and is written in English; the computer must translate it into its own language. (Since C is a high-level language, compilers are required for conversions.)

By the way, the computer needs some functions, like a compiler and an interpreter, to translate high-level languages into low-level languages.

What is the Characteristics of Programming Language

Tell us about some programming language traits that a better programming language should have.

1. A programming language should be very straightforward, simple to learn, and simple to use. It should also be easy to understand and recognize by humans.

2. Any programming language that has the capacity to build complicated structures with ease and that is also simple to use should have abstraction as a key feature.


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

4. A programming language’s efficiency needs to be extremely high in order for it to be quickly translated into machine code and then executed. Additionally, it uses less memory space.

5. A programming language must always be well organised and documented in order to be more useful in the creation of applications.

6. A programming language should include all the tools required for the program’s development, debugging, testing, or maintenance.

7. There should be an Integrated Development Environment (IDE), a single environment for programming languages.

8. The syntax and semantics of a programming language should be very consistent.

When and who started PHP?

PHP was released in 1995 as a server-side scripting language, which was processed in the server so that it could become a website in plain HTML.

Complete knowledge of SQL (Structured Query Language)

SQL is a database query language; it is not a development language. It provides for the correct addition, management, and access of database content. It is a language that enables programmers to carry out the database operations known as CRUD (Create, Read, Update, and Delete).
