This article mainly introduces what the machine language is in the computer, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article.

Only "machine language" can be directly recognized and executed by computer hardware. Machine language is a program language or instruction code that can be directly recognized by the machine, without translation, each opcode has a corresponding circuit to complete it in the computer, or refers to the program language or instruction code that can be directly understood and accepted by the machine without translation.

Correlation

What the computer hardware can directly recognize and execute is the machine language. Machine language is a collection of machine instructions that can be directly recognized and executed by a computer represented by binary code. It is the operation function given to the computer by the computer designer through the hardware structure of the computer. Machine language has the characteristics of flexibility, direct execution and high speed.

Machine language is a program language or instruction code that can be directly recognized by the machine, without translation, each opcode has a corresponding circuit to complete it in the computer, or refers to the program language or instruction code that can be directly understood and accepted by the machine without translation. The machine language uses absolute addresses and absolute opcodes.

Different types of computers have different machine languages, and programs written according to the machine instructions of one computer cannot be executed on another computer. From a use point of view, machine language is the lowest level of language.

An instruction is a statement of machine language, which is a set of meaningful binary codes. The basic format of the instruction is, for example, the opcode field and the address code field, where the opcode indicates the operational nature and function of the instruction. The address code gives the address of the Operand or Operand.

To write programs in machine language, programmers should first memorize all the instruction codes and codes of the computer used. When programming by hand, the programmer has to handle the storage allocation, input and output of each instruction and data, and remember the state of the unit of work used in each step of the programming process. This is a very tedious work. It often takes dozens or hundreds of times more time to write a program than it actually takes to run. Moreover, the program is full of 0 and 1 instruction code, which is not intuitive and error-prone. With the exception of professionals from computer manufacturers, the vast majority of programmers no longer learn machine languages.
