Real meaning of programming language


 Programming language


A computer don't understand  human language as it is a machine.
So in order to interact with a machine
we need to learn a language called machine language or binary language[0 or 1]
In simple words On / Off.
But it is difficult for us to understand or write it.

So in order to communicate with computer we developed a language called programming language / high level language.

This is how a programming language looks like


Computer programs are written in various
programming language which is then converted to machine language using
translators like assembler,compiler & interpreter.

Every application or machine you use it's made from programming language.

From oldest programming language
[ COBOL & Fortran] to the advanced programming language we use today like

and each programming language has its own syntax .So one must learn it before writing a program.
