A high-level language is a programming language intended to streamline computer programming. It is called high-level because it is quite a few steps away from the original code run on a computer’s central processing unit (CPU). High-level source code comprises of easy-to-read structure that is later translated into a low-level language, which can be perceived and run by a specific CPU.
A high-level language is a particular programming language that allows creation of a program in a much easier to understand programming framework and is generally independent of the customer’s hardware architecture.
A high-level language has a higher level of concept from the computer and focuses more on the programming logic rather than the basic hardware elements such as memory address and register usage.
High-level languages are intended to be used by the human operator or the programmer. They are ascribed to as closer to humans. Their programming technique and framework is easier to grasp and execute than low-level languages and the whole code generally concentrates on the specific program to be developed.
A high-level language does not entail dealing with hardware limitations when creating a program. However, every single code written in a high-level language must be translated into machine language before being implemented by the computer.
Most popular programming languages are regarded as high-level languages. Examples include:
- Objective C
Each of these programming languages uses distinct structures. Some are intended for creating desktop software programs, while others are most appropriate for web development. But they are all regarded as high-level since they must be handled by a compiler or interpreter before the code is implemented.
Source code written in languages like C++ and C# must be compiled into machine code to run. The compilation process translates the human-readable structure of the high-level language into low-level language for a particular processor. Source code written in scripting languages like Perl and PHP can be run through an interpreter, which converts the high-level code into low-level language while in progress.
A low-level language is a programming language that works with a computer’s hardware elements and limitations. It has no or only an insignificant level of abstraction in reference to a computer and works to administer a computer’s operational definition.
A low-level language may also be called as a computer’s native language.
Low-level languages are intended to manoeuvre and administer the whole hardware and commands set architecture of a computer directly.
Low-level languages are treated to be closer to computers. Basically, their prime function is to manoeuvre, administer and execute the computing hardware and elements. Programs and applications written in low-level language are directly implemented on the computing hardware without any interpretation or translation.
Machine language and assembly language are common examples of low-level languages.
Low-level languages are useful because programs written in them can be created to run very fast and with a very minimal memory usage. However, they are recognised as difficult to use because they require a deeper knowledge of machine language.
High-level Language vs. Low-level Language
High-level language is where all the innovative things take place and it can be debugged in a much easier manner than in low-level. High-level languages are highly deployable, and they are mostly used to create software which can run on multiple platforms and architectures.
Low-level language is immense and requires a great amount of experience and knowledge. Low-level languages are extremely challenging to understand and to debug by other programmers. Each architecture family has its own set of assembly language, which means that code written for one is impossible to run on the other, meaning it’s not portable.
