This article mainly shows you "what are the differences between machine language, assembly language and high-level language". The content is easy to understand and clear. I hope it can help you solve your doubts. Let the editor lead you to study and learn the article "what are the differences between machine language, assembly language and high-level language".

Differences: 1, the execution efficiency of machine language is high, the programming efficiency of assembly language is not high, but the execution efficiency of high-level language is lower than that of machine language, but the programming efficiency is higher than that of assembly language; 2, the readability of machine language is poor, the readability of assembly language is strong, and the readability of high-level language is high.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Machine language is a language expressed by binary code, and it is the only language that can be directly recognized and executed by the computer. it has the advantages of direct execution, simplicity and fast operation speed, but it is not intuitive and easy to make mistakes. it is difficult to check and debug the program, and it is also very dependent on the machine.

In order to solve the problem that machine language is difficult to understand and remember, assembly language uses names and symbols that are easy to understand and remember to represent the opcodes in machine instructions. This kind of language composed of instruction mnemonics is called assembly language. The machine cannot directly execute programs written in assembly language, it also depends on the machine.

High-level language provides users with a way of working that is close to natural language, can use mathematical expressions, and is relatively independent of the machine. Like assembly languages, machines cannot directly execute programs written in high-level languages.

The difference between machine language, assembly language and high-level language

1. Efficiency:

Machine language: high execution efficiency and high speed

Assembly language: programming efficiency is not high, it is a low-level language

High-level language: the execution efficiency is not as efficient as the machine language, but the programming efficiency is higher than the assembly language.

2. Composition:

Machine language: machine language is a set of instructions arranged by 0 and 1 according to certain rules: it is the only language that a computer can recognize and execute.

Assembly language: an instruction system that uses mnemonics to represent opcodes and operands in machine instructions. Enhanced readability and fast execution

High-level language: a language that is closer to human natural language and mathematical language, and the programs written with it can greatly reduce the work of programmers, so it also has good portability.

3. Type-oriented:

Machine language: it is a machine-oriented language with poor readability.

Assembly language: it is still a machine-oriented language with strong readability

High-level language: simplify the natural language close to people, with high readability.

4. Different characteristics

Machine language:

It has the advantages of direct execution, high speed and low resource consumption. The disadvantages are poor readability, portability and complicated programming.

Assembly language:

The characteristic of assembly language is that it is easy to be recognized and executed by computer. Using it for programming can reduce the space occupied, improve the running speed, and directly control the hardware. When real-time control is needed, it has an irreplaceable important position, but assembly language is more complex and difficult in programming and understanding, especially in data processing or logical operation.

High level language:

It can be understood more accurately by programmers, and it has strong expression ability, many functions, high programming efficiency, fast starting speed and high degree of automation. In most software development, users use high-level language programming to improve programming efficiency. However, when the storage space is small, the execution speed is fast, and the hardware needs to be controlled directly, assembly language programming is applied to optimize the program speed.
