Editor to share with you what are the three stages of the development of language processing programs in computers. I hope you will gain something after reading this article. Let's discuss it together.

The development of language processing program has experienced three stages: machine language, assembly language and high-level language; machine language is a program language or instruction code that machines can directly recognize; Assembly language is any low-level language used in electronic computers, microprocessors, microcontrollers or other programmable devices; high-level language is a machine-independent, process-oriented or object-oriented language.

The development of language processor has gone through three stages: machine language, assembly language and high-level language.

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 computers have their own machine languages, that is, instruction systems. From a use point of view, machine language is the lowest level of language.

Assembly language (Assembly Language) is any low-level language used in computers, microprocessors, microcontrollers or other programmable devices, also known as symbolic language. In assembly language, mnemonics are used to replace the opcodes of machine instructions, and address symbols or labels are used to replace the address of instructions or operands. In different devices, assembly language corresponds to different machine language instruction sets and is converted into machine instructions through the assembly process. Specific assembly language and specific machine language instruction set are one-to-one corresponding, and can not be directly transplanted between different platforms.

High-level language (High-level programming language) is a machine-independent, process-or object-oriented language. High-level language is designed with reference to mathematical language, which is similar to daily conversation. For example, to add two variables and assign a value to the third variable, expressed as var3=var1+var2 in a high-level language.
