What is a program written in assembly language or high level language called?
A program written in assembly language or high-level language is called a source program. The CPU cannot execute it and must be translated into the corresponding target program. A source program is a series of human-readable computer language instructions, mainly aimed at developers. Source program is relative to object code and executable code.

Related introduction:
Source code (also called source program) refers to uncompiled in accordance with a certain A text file written in a programming language specification, which is a series of human-readable computer language instructions.
Source code is code written in assembly language and high-level language. The main target is developers. The applications we usually use are compiled and packaged from source code before being released, and the final result is presented to users and end customers.
Source code is relative to the target code and executable code.

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.

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.

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.

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.

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.

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

Machine language is not a high-level language. It is a low-level language used for computer hardware. It interacts directly with the underlying hardware of the computer. Machine language uses binary encoding to represent instructions and data. Each instruction corresponds to an operation or function of the computer hardware. , High-level language is a programming language that is closer to human language, providing higher abstraction capabilities and development efficiency. Machine language and high-level language play different roles in programming, each with their own advantages and applicable scenarios.

Kuai Technology reported on November 17 that this morning, Shenzhen Kaihong announced that the first KaihongOS humanoid robot based on the open source Hongmeng, jointly developed by it and Leju Robot, was officially released. According to the official introduction, this is an all-things intelligent teaching system equipped with KaihongOS and using robots as the carrier, covering multiple scenarios such as industry and services. This robot is equipped with a blood oxygen heart rate sensor, temperature and humidity sensor, infrared temperature sensor, human body induction sensor, NFC, OLED display, and LED lights. Through multiple joint sensing, it can intelligently execute decisions. At the same time, the robot can also be interconnected with mobile phones, tablets, computers and other devices in real time, getting rid of the traditional wire harness connection method and improving teaching efficiency. At the same time, this robot also has 17
