What is programming language ?

Programming Language

As we know, to communicate with a person, we need a certain language. Likewise, programmers need a language to talk to computers.

This language is called programming language.

Before we learn how to programme, let's figure out what language is.


What is Language?

Language is a means of exchanging thoughts and ideas with other people. A language that can be understood by both parties is necessary for a variety of purposes, such as teaching someone.


What is a Programming Language?

Programmers (developers) communicate with computers using a programming language, which is a computer language. Programming languages (C, C++, Java, Python) can be used to write instructions for a specific task.

Desktop applications, websites, and mobile applications are the primary uses of programming languages.


Types of programming language

1. Low-level programming language

A low-level language is a programming language based on 0s and 1s that is specific to a given machine. Programs written in low-level languages can be executed quickly because the processor doesn't require a compiler or interpreter to run them.

There are two subcategories of low-level language:


i. Machine Language

A programming language known as machine language is a low-level one. 

Additionally, it's referred to as "machine" or "object code." 

As a rule, computer languages are written in binary or hexadecimal (base 16) form, 

making them easier to read. Because computers can understand machine language programmes directly,

 a translator isn't needed to convert the programmes.

The advantage of using machine language over a high-level programming language is that it allows the programmer to execute programmes more quickly.


ii. Assembly Language

In addition to being a low-level programming language, Assembly Language (ASM) is also designed for specific processors.

A symbolic and human-understandable form of the set of instructions is represented by it.

Converting assembly language to machine code is done using an assembler.

Assembler language has the advantage of requiring less memory and less time to run a programme.


2. High-level programming language

In order to create software and websites that are easy to use, the High-Level Programming Language (HLL) was created. A compiler or interpreter is needed to translate the programme into machine language for this programming language (execute the program).

It is much easier to read, write, and maintain code in a high-level language.

Python, Java, JavaScript, PHP, C#, C++, Objective C, Cobol, Perl, Pascal, LISP, FORTRAN, and Swift are all examples of high-level programming languages, as are Python, Java, JavaScript, and PHP.


The three parts of a high-level language are:

i. Procedural Oriented programming language

The procedure call concept is the foundation of the Procedural Oriented Programming (POP) language. Routines or functions are small procedures that make up a programme.

An IDE, Adobe Dreamweaver, Microsoft Visual Studio, or other programming editors, can be used to create a programme written in a procedural-oriented programming language.

Using POP language, programmers can more easily keep track of the program's progress and reuse code across different sections of the program.

Example: C, FORTRAN, Basic, Pascal, etc.


ii. Object-Oriented Programming language

Based on the concept of objects, Object-Oriented Programming (OOP) is a programming language Objects are the smallest units of code in this programming language. Inheritance, polymorphism, abstraction, and other real-world concepts are incorporated into the code to improve the program's reusability, efficiency, and usability.

The primary benefit of object-oriented programming (OOP) is the speed and ease with which it can be implemented, maintained, modified, and troubleshot.

Example: C++, Java, Python, C#, etc.


iii. Natural language

Human languages such as English, Russian, German, and Japanese all have elements of natural language. Automated systems utilize it to decipher, manipulate, and interpret human speech and writing. Developers use it to perform tasks such as translation, automatic summarization, Named Entity Recognition (NER), relationship extraction, and topic segmentation.

With natural language, users can ask questions about any topic and receive an immediate response in a matter of seconds.


3. Middle-level programming language

In between low-level and high-level programming languages, middle-level programming languages are used. Intermediate programming language and pseudo-language are other names for it.

If you're looking for an intermediate language, you'll find that it has all the advantages of a high-level language while being easier to learn.

Example: C, C++
