machine language

Machine language is the lowest level language in computer architecture, and it is also a programming language that computers can directly understand and execute. It uses binary code to represent instructions and data. Machine language has the advantages of high execution efficiency and low-level hardware control, but it is difficult to write and manage and relies on computer architecture and instruction sets. The emergence of high-level programming languages ​​solves the shortcomings of machine language and makes it easier for programmers to write and manage programs.

What is machine language

Machine language is the lowest level language in computer architecture, and it is also a programming language that computers can directly understand and execute. It is composed of binary code, using 0 and 1 to represent different instructions and data. Machine language is the language of computer hardware and is closely related to a specific computer architecture and instruction set. In machine language, each instruction corresponds to an operation of the computer, such as loading data, storing data, arithmetic operations, etc. These instructions are binary codes composed of a series of 0s and 1s.

Machine language is the basic instruction set of the computer. It can directly operate the computer hardware and complete various tasks. Compared with high-level languages, machine languages ​​are closer to the bottom layer of computer hardware and therefore have higher execution efficiency. However, because machine language uses binary representation and is difficult to understand and write, usually only computer professionals or programming experts use machine language programming.

When using machine language programming, programmers need to understand the underlying instruction set and hardware structure of the computer, as well as the specific binary encoding method. By writing instructions and data in binary form and storing them in the computer's memory, the computer can execute the instructions in sequence and complete various complex calculations and operations.

The main advantage of machine language is high execution efficiency, because the computer directly executes binary instructions without translation and interpretation. In addition, machine language can also directly interact with hardware and provide low-level control of the computer, enabling more sophisticated operations and optimization.

However, machine language also has some shortcomings. First, writing and debugging machine language is difficult because a large amount of binary code needs to be written and managed manually, which is prone to errors. Secondly, because machine language is related to specific computer architecture and instruction sets, different computer hardware may have different machine languages, which makes program porting and cross-platform development difficult.

In order to solve the shortcomings of machine language, people developed high-level programming languages. High-level programming language is relative to machine language. It is written in a form that is closer to human language and has higher readability and maintainability. High-level programming languages ​​use a compiler or interpreter to convert source code into machine language so that the computer can execute it. The emergence of high-level programming languages ​​makes it easier for programmers to write and manage programs, while also improving the portability and cross-platform nature of programs.

In short, machine language is the lowest level language that a computer can directly understand and execute. It uses binary code to represent instructions and data. Machine language has the advantages of high execution efficiency and low-level hardware control, but it is difficult to write and manage and relies on computer architecture and instruction sets. The emergence of high-level programming languages ​​solves the shortcomings of machine language and makes it easier for programmers to write and manage programs.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
