High-level language - GCSE Computer Science Definition

Reviewed by: James Woodhouse

Last updated

A high-level language is a type of computer programming language that is easy for humans to read and write. It is designed to be similar to human language, making it simpler to understand and use when compared to low-level languages like machine code. High-level languages, such as Python, Java, and C++, allow programmers to write instructions using words and symbols, rather than numbers. These languages need to be translated into machine code by a compiler or an interpreter so that the computer can understand and execute the instructions. High-level languages are widely used because they make it quicker and easier to create and modify software programs.
