The difference between machine language, assembly language and high-level language
The difference between machine language, assembly language and high-level language
The differences between machine language, assembly language and high-level language are as follows:
Machine language
Machine language It is an instruction set system. It is a language expressed in binary code. It is the only language that a computer can directly recognize and execute. It has the advantages of being directly executable by a computer, concise, and fast in operation. However, it is not intuitive and very It is error-prone, difficult to check and debug the program, and is also highly dependent on the machine.
Assembly language
Assembly language is a machine-oriented programming language. It is used to solve the shortcomings of machine language that is difficult to understand and remember, using names that are easy to understand and remember. The sum symbol represents the operation code in the machine instruction. Using symbols to replace the binary code of the machine language turns the machine language into assembly language; therefore, assembly language is also called symbolic language.
Programs written in assembly language cannot be directly recognized by the machine. A program is required to translate the assembly language into machine language. This translation program is called an assembler. The assembler is a language processor in the system software. system software. The process of translating assembly language into machine language by the assembler is called assembly.
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 machines. Like assembly language, machines cannot directly execute programs written in high-level languages.
High-level language does not refer to a specific language, but includes many programming languages, such as the currently popular java, c, c, C#, pascal, python, etc.
High-level languages have stronger expression capabilities, can easily express data operations and program control structures, can better describe various algorithms, and are easy to learn and master. However, the program code generated by its compilation is generally longer than the program code designed in assembly language, and the execution speed is also slower.

What are the characteristics of machine language, assembly language, and high-level language?
Apr 22, 2021 pm 04:00 PM
Characteristics of machine language: difficult to learn, understand, and understand; not universal; requires manual allocation of memory; and runs fastest. The characteristics of assembly language: the execution efficiency of the program is very high, it takes up little storage space, and it runs fast; it lacks versatility and the program is not easy to transplant. Characteristics of high-level languages: easy, certain versatility, and cannot be directly recognized and executed by computers.
What are the components of assembly language?
Aug 15, 2022 pm 03:44 PM
The components of assembly language: 1. Transfer instructions, including general data transfer instructions, conditional transfer instructions, etc.; 2. Logical operations, which are used to perform arithmetic and logical operations; 3. Shift instructions, used to operate registers or memory The number is moved a specified number of times; 4. Bit operations, including test instructions BT, bit test and set instructions BTS, etc.; 5. Control transfer, including unconditional transfer instructions JMP, conditional transfer instructions "JCC/JCXZ", etc.; 6. String Operation, used to operate on data strings; 7. Input and output, used to exchange data with peripheral devices.
What programming language is used to write programs that can be directly executed by computers?
Mar 24, 2021 pm 05:05 PM
Programs that computers can directly execute are written in "machine language". Machine language is a programming language or instruction code that the machine can directly recognize without translation. Each operation code has a corresponding circuit inside the computer to complete it, or it refers to a programming language that can be directly understood and accepted by the machine without translation. or instruction code.
What is the system software that can translate source programs written in high-level languages into target programs?
Jan 22, 2021 pm 05:36 PM
System software that can translate source programs written in high-level languages into target programs is a "compiler". A compiler is a translation program implemented using a generative implementation approach; it takes a source program written in a high-level programming language as input, and uses a target program expressed in assembly language or machine language as output.
What is a computer's instruction set called?
Dec 24, 2020 pm 03:29 PM
The set of instructions for a computer is called "machine language". Machine language is a collection of machine instructions expressed in binary code that a computer can directly recognize and execute; it is the operating function given to the computer by the computer designer through the computer's hardware structure.
Is assembly language a high-level language?
Jan 30, 2023 pm 03:14 PM
Assembly language is not a high-level language; it is a low-level language like machine language. The difference between assembly language and high-level language: 1. The programming efficiency of assembly language is not high, while the programming efficiency of high-level language is higher than that of assembly language; 2. The readability of high-level language is higher than that of assembly language; 3. Assembly language is a Machine language, while high-level language is simplified and close to human natural language.
What is the difference between assembly language and c language?
Jan 06, 2023 pm 01:48 PM
Differences: 1. Because assembly language is essentially a mnemonic for machine language and is a language that directly faces the CPU, assembly language operates more efficiently than C language; 2. Assembly language has strong controllability of hardware, and C language Hardware controllability is relatively poor; 3. The object code of assembly language is small, and the object code of C language is large; 4. Assembly language is difficult to maintain, but C language is easy to maintain; 5. The portability of assembly language is very poor, and C language is portable. The performance is very good; 6. Assembly language is easier to learn than C language, because assembly language requires a lot of programming knowledge and is very complicated.
Analyzing ROP attacks
Feb 18, 2024 pm 12:46 PM
ROP attack explanation With the continuous development of information technology, network security issues have gradually attracted people's attention. Various new network attack methods emerge in endlessly, and one of the most widely used attack methods is the ROP (Return Oriented Programming) attack. This article will explain in detail the ROP attack. ROP attack (ReturnOrientedProgrammingAttack) is a method that uses the instruction sequence that already exists in the program to construct a new
