英语翻译
An instruction is made of operations that specify the function to be performed and operands that the data to be operated on.For example,if an instruction is to perform the operation of adding two numbers,it must know (1) what the two numbers are and (2) where the two numbers are.When the two numbers are stored in the computer’s memory,they have an address to indicate where they are,so if an operated refers to data in the computer’s memory it is called an address.The processor’s job is to retrieve instructions and operands from memory and to perform each operation.Having done that,it signals memory to send it the next instruction.
This step-by-step operation is repeated over and over again at awesome speed.A timer called clock releases precisely timed electrical signals that provide a regular pulse for the processor’s work.The term that is used to measure the computer’s speed is borrowed from the domain of electrical engineering and is called a megahertz (MHz),which means million cycles per second.For example,in an 8 MHz processor,the computer’s clock ticks 8 million times to every 1 second tick of an ordinary clock.
A processor is composed of two functional units—a control unit and an arithmetic/logic unit—and a set of special workspaces called registers.
The control unit

指令是行动的具体职能和执行运算的数据进行操作.例如,如果一个指令是执行的运作增加了两个号码,它必须知道（ 1 ）什么这两个号码和第（ 2 ）在这两个数字.当两个数字都存储在计算机的内存,他们的讲话表明他们在那里,所以,如果一个经营是指数据在计算机的内存被称为地址.该处理器的工作就是检索指令和操作数从记忆并执行每个操作.这样做了,它标志着内存发送下一指示.
这步操作是重复一遍又一遍在可怕的速度.阿计时器所谓的时钟精确定时发布电信号,提供定期脉冲处理器的工作.这个词是用来衡量计算机的速度是借来的从域的电气工程和被称为兆赫（ MHz ） ,这意味着万赫兹.例如,在一个8兆赫处理器,计算机的时钟跳动800万倍,每1秒剔一个普通的时钟.
处理器由两个功能单位,一个控制单元和算术/逻辑单元和一套特殊的工作要求登记.
