This article mainly introduces the characteristics of machine language, assembly language and high-level language in the computer network. It is very detailed and has a certain reference value. Interested friends must finish reading it!

The characteristics of machine language: difficult to learn, difficult to understand, difficult to understand; no versatility; need to allocate memory artificially; run the fastest. The characteristics of assembly language: the execution efficiency of the program is very high, the storage space is small, and the running speed is fast; lack of versatility, the program is not easy to transplant. The characteristics of high-level language: easy, versatile, computers can not directly identify and execute.

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

Machine language

Machine language is a system of instruction set. it is a language expressed by binary code. it is the only language that can be directly recognized and executed by computer. it has the advantages of direct execution, simplicity and fast operation speed by computer. however, it is poor intuitive, very error-prone, difficult to check and debug the program, and is highly dependent on the machine.

Features:

Difficult to learn, understand, and understand.

Machine language programs are made up of a series of instruction codes, which in turn are made up of hexadecimal numbers, which have nothing to do with the functions to be implemented.

No versatility.

Machine language is the most direct and primitive language, which is completely dependent on a specific computer system.

Memory needs to be allocated artificially

The machine language program and all the parameters used in its operation, like the high-level language, need to be stored in the memory of the host computer. However, where the memory is stored and how to arrange it reasonably need to be artificially determined by the programmer according to the specific conditions of the system and programs under the computer.

The fastest running speed

Machine language is the only language that the computer can recognize and function directly. It does not need to go through the compilation process, and the execution speed is very fast, which is hundreds of times higher than that of the high-level language.

Save memory space

Function is more perfect

The functions that can be accomplished by the machine language may not be realized by the high-level language, and so can the functions that can be realized by the high-level language.

Can be used to design extended functions

Assembly language

Assembly language is a machine-oriented programming language. In order to solve the problem that machine language is difficult to understand and remember, it uses names and symbols that are easy to understand and remember to represent the operation code in machine instructions. In this way, the binary code of machine language is replaced by symbols, which turns machine language into assembly language, so assembly language is also called symbolic language.

The program written in assembly language cannot be directly recognized by the machine, so it is necessary for a program to translate the assembly language into machine language. this kind of program that plays the role of translation is called assembler, and the assembler is the language processing system software in the system software. The process by which an assembler translates an assembly language into a machine language is called assembly.

Features:

Mnemonic instructions correspond to machine instructions one by one. The program written in assembly language has the advantages of high efficiency, small storage space and fast running speed. Assembly language can write the most optimized program, and can reflect the actual operation of the computer.

Programming is more difficult than high-level languages. Because assembly language is machine-oriented, programmers must have a deep understanding of computers before they can program in assembly language.

Assembly language can deal directly with memory and interface circuits, and can also apply for interrupts. Therefore, the assembly language program can directly manage and control the hardware equipment.

Lack of versatility, the program is not easy to transplant. The assembly languages of different computers cannot be common, because each of them has its own assembly language suitable for the characteristics of its own model. However, mastering one kind of computer assembly language is helpful to learn the assembly language of other computers.

high-level language

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.

High-level language has stronger expression ability, can easily express the operation of data and the control structure of the program, can better describe various algorithms, and is easy to learn and master. However, the program code generated by it is generally longer and slower than the program code designed in assembler language.

Features:

Close to natural language and mathematical language, easy for people to master

Independent of the machine, has a certain degree of versatility

Computers cannot directly recognize and execute programs written in high-level languages

Programs written in high-level languages greatly improve the efficiency of writing.
