Programming is an art. A Programming Language is used to write computer programs. A Computer program is nothing but series of instructions or lines that can be understood by humans and read by the compilers which further is translated into machine code so that computer can understand what we have written. The vocabulary of language must be simple and easy to understand.

Learning a software development language is a real-world exercise because programming is learnt by doing. More you do more you learn. That's why computer programmer job interviews questions are designed to test practical programming skills or abilities of the candidate. In software development, there are several programming languages that can be used for a wide variety of reasons.

C# should be used for any Windows development purpose. PHP is excellent for rapid prototyping, what a web site should act like. HTML is another language which can be learnt very easily online for making static WebPages. Similarly CSS and JavaScript can be learnt for web development purposes. We have 8051 assembly language which can be used to program 8051 microcontroller.

This is a list of some popular programming languages :

PHP: Hypertext Preprocessor

Server-side HTML embedded scripting language. It provides web developers with a full suite of tools for building dynamic websites

C#

C# (pronounced C Sharp) is a computer language developed by Microsoft but made available to the general public through international standards

C programming

It is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories.

Ruby Programming Language

Ruby is a dynamic, reflective, general purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features

The Java

Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation).

Python Programming Language

Python is a general-purpose high-level programming language whose design philosophy emphasizes code readability

Visual Basic .NET 

Visual Basic .NET (VB.NET) is an object-oriented computer programming language that can be viewed as an evolution of Microsoft's Visual Basic (VB) which is generally implemented on the Microsoft .NET Framework.
