1, Introduction

Programming is the Chinese abbreviation of programming, which means that a computer can solve a problem on its behalf and specify a certain operation mode for the computing system. It is the process that the computing system runs according to this computing mode and finally gets the corresponding results.

In order to make the computer understand people's intentions, human beings must tell the computer the ideas, methods and means of the problems to be solved in a form that the computer can understand, so that the computer can work step by step according to people's instructions and complete a certain task. This communication process between people and computing systems is programming.

2. Assembler

Assembler. Using assembly language to write computer programs, programmers still need to be very familiar with the hardware structure of computer systems, so the program design itself is still inefficient and cumbersome. However, due to the close relationship between assembly language and computer hardware system, assembly language is still a very effective programming tool in some specific occasions, such as system core programs and real-time control programs that require high space-time efficiency.

3, the implementation principle

Computers cannot directly identify, understand and execute source programs other than machine language, and all of them must be converted into directly executable programs by computers in some way. There are two ways to convert a source program written in a high-level programming hardware programming language into a machine object program: interpretation and compilation.
