Assembly Language Vs. High-Level Language: Find the Difference Between Assembly Language and High-Level Language
Both of these are types of computer languages, but there is a significant difference between assembly language and high-level language. In this article, we will discuss the difference between them both. But let us first understand a bit more about each of these individually.
What is an Assembly level language?
An assembly language is a type of low-level language of the computer that lets users write various programs by making use of the alphanumeric codes for a set of instructions instead of the numeric codes. IBM PC DOS is a commendable example of a large assembly language of the present time.
What is a High-level language?
A high-level language is a machine-independent type of language. It lets users write various programs in such a language that resembles the English words (and alphabets) and all the familiar mathematical symbols. The very first high-level language was the COBOL language. C#, Python, etc., are a few examples of high-level languages.
Difference Between Assembly Language and High-Level Language
Here is a list of the differences present between Assembly Language and High-Level Language.
| Parameters | Assembly Language | High-Level Language |
| Conversion | The assembly language requires an assembler for the process of conversion. | A high-level language requires an interpreter/ compiler for the process of conversion. |
| Process of Conversion | We perform the conversion of an assembly language into a machine language. | We perform the conversion of a high-level language into an assembly language and then into a machine-level language for the computer. |
| Machine Dependency | The assembly language is a machine-dependent type of language. | A high-level language is a machine-independent type of language. |
| Codes | It makes use of the mnemonic codes for operation. | It makes use of the English statements for operation. |
| Operation of Lower Level | It provides support for various low-level operations. | It does not provide any support for low-level languages. |
| Access to Hardware Component | Accessing the hardware component is very easy in this case. | Accessing the hardware component is very difficult in this case. |
| Compactness in Code | The code is more compact in this case. | No code compactness is present in this case. |
| Type of Processor | The program that we write for one processor in an assembly language will not run on any other processor type. It means that it is processor-dependent. | This language is processor-independent. It means that the programs that we write using high-level languages can easily run on any processor independent of its type. |
| Accuracy | It has better accuracy. | Accuracy is much lesser in this case. |
| Performance | An assembly language performs better than any high-level language, in general. | The performance is comparatively not so good. |
| Length of Executable Code | It is shorter in assembly language. | It is larger in a high-level language. |
| Time Taken in Code Execution | Execution of code takes less time in this case because the code is not very large. | It takes up more time for execution because it needs to execute a large code. |
| Efficiency | It is way more efficient because of the shorter executable codes. | It is comparatively less efficient because the executable codes are comparatively longer in length. |
| Reading of Pointers | We can do that directly at a physical address in the case of an assembly language. | It is not possible to do so in the case of a high-level language. |
| Extra Instructions | We don’t need that in the case of an assembly language. | This language must give some extra instructions for running any code on the computer. |
| Ease of Understanding | It is very difficult to debug and understand the code of an assembly language. | It is very easy to debug and understand the code of an assembly language. |
