Programming language |Short Overview

Programming language

A programming language is a formal computer language designed to communicate instructions to a machine, mainly a computer. Programming languages can be used to create programs to control the behaviour of a device or to express algorithms. A language that is designed to represent logics in the computer. A programming language is termed to as command to the appliance Or a language that easily interact with a machine.

Programming languages

Programming languages are categorised into two types Low-level language and High-level language. Low level, language is not understood able by the human, so it is also termed as machine language, and on another hand, High-level language is human readable language.

There is numerous Programming language some of these are:

JAVA: Java is a general-purpose, high-level programming language developed by Sun Microsystems. A small team of engineers, known as the Green Team, started the language in 1991.

Python:  An interpreted language, Python has a design philosophy which emphasises code readability (notably using whitespace indentation to delimit code blocks rather than curly braces or keywords), and a syntax which allows programmers to express concepts in fewer lines of code than possible in languages such as C++ or Java.

C: C is a high-level and general purpose programming language that is ideal for developing firmware or portable applications. Originally intended for writing system software, C was developed at Bell Labs by Dennis Ritchie for the Unix Operating System (OS) in the early 1970s.

C++: It is a general purpose language. Object Oriented language. Most features of JAVA is derived from C++

C#: C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its.NET initiative led by Anders Hejlsberg.

PHP: General purpose scripting language most probably used in web application.

JavaScript: It is lightweight and most commonly used as a part of web pages, whose implementations allow the client-side script to interact with the user and make dynamic pages.

DartDart is an open-source general-purpose programming language initially developed by Google and later approved as a standard by Ecma (ECMA-408).

HTML: HTML is a Markup Language which means you use HTML to only “mark up” a text document with tags that tell a Web browser how to structure it to display. Originally, Hyper Text Markup Language was developed with the intent of defining the structure of documents like headings, paragraphs, lists, and so on.

VBScript: VBScript is based on the Visual Basic programming language but is much simpler. A scripting language developed by Microsoft and supported by Microsoft’s Internet Explorer Web browser.

Nowadays many programming languages are built, and each of this language has own functionality. 

A programming language is a notation for writing programs, which are specifications of computation or algorithm.Some, but not all, authors restrict the term “programming language” to those languages that can express all possible algorithms. Traits often considered important for what constitutes a programming language include:

Function and target

A computer programming language is a language used to write computer programs, which involve a computer performing some computation or algorithm and possibly control external devices such as printers, disk drives, robots, generally and so on. For example, PostScript programs are frequently created by another program to control a computer printer or display. More generally, a programming language may describe computation on some, possibly abstract, much accepted that a complete specification for a programming language includes a description, possibly idealized, of a machine or processor for that language. In most practical contexts, a programming language involves a computer; consequently, programming languages are usually defined and studied this way.Programming languages differ from natural languages in that natural languages are only used for interaction between people, while programming languages also allow humans to communicate instructions to machines.


Programming languages usually contain abstractions for defining and manipulating data structures or controlling the flow of execution. The practical necessity that a programming language support adequate abstractions is expressed by the abstraction principle; this principle is sometimes formulated as a recommendation to the programmer to make proper use of such abstractions.

Expressive power

The theory of computation classifies languages by the computations they are capable of expressing. All Turing complete languages can implement the same set of algorithms. ANSI/ISO SQL-92 and Charity are examples of languages that are not Turing complete, yet often called programming languages.
Markup languages like XML, HTML, or troff, which define structured data, are not usually considered programming languages. Programming languages may, however, share the syntax with markup languages if a computational semantics is defined. XSLT, for example, is a Turing complete XML dialect. Moreover, LaTeX, which is mostly used for structuring documents, also contains a Turing complete subset.

The term computer language is sometimes used interchangeably with programming language. However, the usage of both terms varies among authors, including the exact scope of each. One usage describes programming languages as a subset of computer languages.In this vein, languages used in computing that have a different goal than expressing computer programs are generically designated computer languages. For instance, markup languages are sometimes referred to as computer languages to emphasize that they are not meant to be used for programming.

Another usage regards programming languages as theoretical constructs for programming abstract machines, and computer languages as the subset thereof that runs on physical computers, which have finite hardware resources.John C. Reynolds emphasises that formal specification languages are just as much programming languages as are the languages intended for execution. He also argues that textual and even graphical input formats that affect the behaviour of a computer are programming languages, despite the fact they are commonly not Turing-complete, and remarks that ignorance of programming language concepts is the reason for many flaws in input formats.
