Programming languages can be categorized by their level of abstraction from machine language. Low-level languages have minimal abstraction and are closer to machine-understandable binary, while high-level languages are more abstract and user-friendly. Low-level languages map directly to hardware instructions but are difficult for humans, whereas high-level languages require translation to machine code but are easier for programmers. Programs transition between these levels through compilation and interpretation.

1. LEVELS OF PROGRAMMING LANGUAGES
• Levels in programming languages is nothing but level of abstraction.
• Binary language==Machine understandable language.
• 0-Level Abstraction between Machine language & Programming language==
Low level 1GL.
• 1-Level Abstraction between Machine language & Programming language==
Low level 2GL.
• Rest of languages are High level language(based on abstraction level High
level language can be divided into Mid level language, High level language,
Very high level language)

2. 3 LEVELS OF PROGRAMMING LANGUAGES

3. LOW LEVEL PROGRAMMING LANGUAGE
• Here The word "low" refers to the small or nonexistent amount
of abstraction between the language and machine
language(machine understandable language).
• A low-level programming language is a programming language
that provides minute or no abstraction from a computer's
instruction set architecture.
• A low-level programming language is closer to the native
language of a computer (binary).
• Programs and applications written in low-level language are
directly executable on the computing hardware without any
interpretation or translation.

4. LOW LEVEL LANGUAGES ARE CLOSER TO
MACHINE LANGUAGE
• As low level programming language is closer to the machine
language which is binary, This makes them harder for
programmers to understand.
• A program written in a low-level language can be made to run
very quickly, with a small memory footprint.

5. HIGH LEVEL LANGUAGE
• A high-level language is any programming language which is closer to
human languages.
• As compared to machine languages, A high-level language enables
development of a program in a much more user-friendly programming
context and it is generally independent of the computer's hardware
architecture.
• A high-level language has a higher level of abstraction from the computer
and focuses more on the programming logic rather than the underlying
hardware components such as memory addressing and register utilization.
• The main advantage of high-level languages over low-level languages is
that they are easier to read, write, and maintain.

6. TRANSLATION OF HIGH LEVEL LANGUAGE
TO LOW LEVEL LANGUAGE
• Programs written in a high-level language must be translated
into machine language by a compiler or interpreter.
