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.
Levels of programming languages
- 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.
