High Level and Low Level programming Languages

What are High Level and Low Level Languages?

Programming languages are basically classified into two main typesLow Level and High Level.

What is a Low-Level language?

Low-level languages are those languages that are closest to machines, which means machines can easily understand low-level languages as compared to human beings.

Types of Low-level language:

  1. Machine Language.
  2. Assembly Language.

Machine Language or machine code is consists of binary digits (zeros and ones) that understood by a computer.

But there is nothing like 0 and 1 in a computer, means there is no physical significance of 0 and 1. These are two states. Basically, we store any information in two states in a computer, and for identification we call one as 1 and the another 0.

Assembly language is another low-level programming language, but a computer cannot understand the assembly language, computers only understand the Machine language (0s, and 1s).

How to run Assembly language in a computer?

However it is a low-level language, but you can not run Assembly language on a computer directly. You have to translate it to machine code through the Assembler.

Its (Assembly language) code format is close to machines, that’s why it is called low-level language.

Machine VS Assembly Language

Computers only understand the Machine language. But it is very difficult to understand by human beings.Assembly language is only understood by humans. It is easier to write and maintain than the machine language.
The machine code is directly executed by the computer.The assembler is used to convert the assembly code into machine code.
Execution is fast because all the data is already present in binary format.Assembly language is only understood by humans. It is easier to write and maintain than machine language.

What are High-Level Languages?

High-level languages are the opposite of low-level languages, which means high-level languages can easily understand by human beings. Python, Java, C/C++ are popular examples of high-level languages.

The high-level type languages are meant for humans so that human beings can easily learn them to build computer programs.

These languages cannot be understood by a machine. You can run your program on a computer after converting your program into the machine or binary code through the translator (compiler).

High-Level VS Low-Level Languages

It is a programmer-friendly language (Easy to learn or understand).It is a machine-friendly language.
It is easy to maintain and debug.It is hard to maintain and debug.
It consumes more memory in comparison to low-level languages.It consumes less memory.
It can run on all the platforms.It is machine-dependent.
