说明：  汇编大多是指汇编语言，汇编程序。把汇编语言翻译成机器语言的过程称为汇编。在汇编语言中，用助记符(Memoni)代替操作码，用地址符号(Symbol)或标号(Label)代替地址码。这样用符号代替机器语言的二进制码，就把机器语言变成了汇编语言。于是汇编语言亦称为符号语言。用汇编语言编写的程序，机器不能直接识别，要由一种程序将汇编语言翻译成机器语言，这种起翻译作用的程序叫汇编程序，汇编程序是系统软件中语言处理的系统软件。
(Compilation mostly refers to assembly language, assembler. The process of translating assembly language into machine language is called assembly. In assembly language, the use of mnemonics (Memoni) instead of the opcode, address symbol (Symbol) or label (Label) instead of the address code. Thus replacing the binary code of machine language with symbols, the machine language is transformed into assembly language. Assembly language is also called symbolic language. Programs written in assembly language, the machine can not be directly identified by a program to be assembly language into machine language, the translation function that assembler program assembler is a system software system software in processing language.)
