Difference between low-level language and high-level language

September 26, 2022

Low-level languages and high-level languages both are programming languages. The main difference between a high-level programming language and a low-level programming language is that high-level languages are designed to be more easily understood by humans, while low-level languages are designed to be more easily understood by machines.

High-level language

High-Level Language (HLL) is a programming language that uses a higher-level abstraction than C language or C++ language. HLLs are often easier to learn and use than lower-level languages, and they’re generally faster to write and execute.

A good example of a high-level language is Python. Python provides many useful features, including object-oriented programming, dynamic typing, and automatic memory management. These features make it easier to program than C/C++, but they don’t require any special knowledge of how computers work.

Low-level language

Low-Level Language (LLL) is a term used to describe a programming language that is not high-level. In contrast to high-level languages, LLL does not have any abstractions. Low-level languages are often used to write operating systems, compilers, and assemblers.

Low-level languages work directly with a computer’s hardware and instruction set architecture.

Low-level language has some disadvantages. For example, this language is too close to the hardware, which makes it harder to structure some programs. Be careful when using it to avoid making mistakes that could significantly increase the work and revision of the code.

Related FAQs

What is the difference between high and low-level language?

High-level languages use a compiler or interpreter for machine code translation, while low-level language uses an assembler to translate machine language instructions directly. Memory efficiency for these languages is very low.

What is a low-level language example?

Examples of low-level languages are machine and assembly code.

What is a high-level language example?

Ruby, etc.

What are the features of high-level language?

High-level language features include but are not limited to automatic memory management, garbage collection, interfacing with the kernel, extensive error checking, and complex arithmetic or boolean expressions.
