Programming Language
  
　　A programming language is a language used to% rite instructions for the computer. The purpose of a programming language is to allow the programmer to express data processing activities in a symbolic manncr without regard to the details that the machine has to know ．For example, when a programmer writes ULTIPLY HOURS TIMES RATE, these words are-meaningless to the machine. MULTIPLY must reed into a code that means multiply. HOURS and L-ATE must be turned into memory locations where one items of data are actually located. The ramming statements that are written by the programmer are called source language, and they are turned into the computer's machine language by translate programs called assemblers，compilers and interpreters．
   
　　Programming languages fall into two major categories：low-level assembly languages and high-level languages．Assembly languages are available for every CPU family, and they translate one line of code into one machine language instruction．High-level languages translate programming statements into several machine instructions．

　　程序设计语言是一种用于编写计算机指令的语言。程序设计语言的目的是让程序设计者在不考虑机 器是否能识别细节的情况下，以符号的方式表达对数据的处理活动。 例如，当程序设计者写Multiply Hours Times Rate，这些字对机器来说是毫无意义的，Multiply必须被转换成代表其意义的代码。Hours和Rate必须被变成存储单元，这些数据项应在其中。由程序设计者所写的程序设计语句叫做源语言，这些程序设计语句被称为叫做汇编程序、编泽程序、解释程序的翻译程序转 换成计算机的机器语言。
    
　　程序设计语言主要分成两类：低级汇编语言和高级语言。汇编语言用十每一个CPU家族。他们把一 行代码转换成一个机器语言指令。 高级语言把程序设计语句转换成几个机器指令。
