What is a Programming Language
Updated on 7 November, 2019
A programming language is a set of commands, instructions, and rules for the computer to perform a specific task.
A computer programming language allows us to give instructions to a computer in a language the computer understands.
Just like our human communication language for example 'English' we use to communicate with each other on a daily basis.
In a digital world, we need to know the programming language to communicate with the computer.
The programming languages have also various types, mainly it is classified into two categories:
- High-Level Language
- Low-Level Language
#1 - High-Level Language
High-level programming languages are mainly designed to solve real-world problems.
It is much easier to learn and code as compared to low-level languages, but it needs an interpreter or compiler to convert into machine language.
The instructions in these languages have closely resembled human language, so it makes easy to find errors and bugs.
It is further divided into three categories, but now we don't need to know about this because this is an advanced topic.
#2 - Low-Level Language
The word "low" refers to the small amount of abstraction between the language and machine language; because of this, low-level languages are sometimes described as being "close to the hardware".
The machine languages don't need any compiler to convert, because it is directly understood by pc.
But for human it is really hard to code because it works in the 0's and 1's form.
So that low-level language is only used by the expert, he needs details knowledge of hardware and software.
And it is not portable.
Low-level language includes assembly and machine language.
I hope you got an answer and understood the meaning of programming language.
