(2)正文:

 A processor is a functional unit that interperts and carries out instructions. Evevry processor comes with a unique set of operations sunch as add,store,or load that represent the processor's instruction set.Computer designers are fond of calling their computer machines,so the instruction set is somethings referred to as machine instructions and the binary language in which they are written is called machines language! you shouldn't  confuse the processor's instruction set with the insteuctions fond in high-level programming language, sunch as Basic or pascal!处理器翻译和运行指令,每一个处理器都有一组独一无二的操作码,例如 add store load ,由这些操作码组成了操作系统,研发人员喜欢称自己电脑为机器,那么指令集有时候也称之为机器指令,和二进制写成的机器语言,不能将处理器指令集和高级程序言语混淆,比如说 basic 或者 pascal.An instruction is  made up of operations that specify the function to be performed and operands that represent the data to be operated on.for example,if an instruction is to perform the operation of adding two numbers,it is know what the two numbers are and where the two number are. when the numbers are stored in the computer's memory, they have thier addresses to indicate where they are. so if an operand refers to  date in the computer's memory it is called the an address. the processor's job is to retrieve instructions and operands from memory and to perfrom each operation,having done that,it signals memory to send it the next instruction.指令有制定要完成的操作功能,和要操作的数据组成。例如两个数字相加,要知道两个数字是什么,两个数字在哪里,当数字存储进入了电脑内存,有指明其位于何处的地址,当操作数指引的是计算机中的内存数据,则成为地址,处理器的工作及时取出指令和从内存中取出操作数,并且每一执行,当处理器做完这些之后就通知存储器送来下一条命令。the ste-by-step operation is repeated over and over again and awesome speed. a timer called a  clock release precisely timed electrical signals thar provide a regular pulse for the processor's work. the term that is used to measure the computer's speed is borrow from the domain of  electrical engineering and is called a  megahertz(Mhz),which means million cycles per second. for example,in an 8Mhz processor, the computer's clock tick 8 million times  to every 1 second tick of an ordianry clock.这种步进操作以惊人的速度一遍又一遍的重复,一个称为时钟的的计时器准时准确的发出,为处理器提供规律的电脉冲,测试计算机术语是从电工领域借来的,称为兆赫,每秒百万个周期,例如在普通时钟的一秒,而在8Mhz的处理器中,计算机的时钟每秒滴答了800万次。a processor is composed of two functional units - a control unit and an arithmetic/logic unit  and a set of special workspaces calles registers.一个处理器由两个功能部件组成,控制部件和算术和逻辑运算组件与一组称之为寄存器的特殊工作空间组成。

后记:
及时反馈,这是人类的本性,我总是渴望自己的付出,能立马看到效果。争一时之快,给自己带来很多的麻烦。处处攀比对自己的成长也是蛮不利的,轻易的表露自己,每天都在和别人争斗,还有什么心情拿来自我成长。人最重要的是得面对自己,自己才是最大的敌人。
最近在看教父,普里奥.马佐写的,习大大也有推荐,关于男人的世界,我们要去适应莫名其妙的侮辱。完成了一些小事之后,自己会有些得意,有些自满。但是我是不能很好的做到不露声色,过多的去表露自己的想法,暂时的成果,并不能让你获得成长,但是获得成果后得意洋洋,的确会给你带来一些不必要的麻烦。
其实人是孤独的,虽然我们发明了语言,但是我们用语言去表达自己的想法,但是语言并不能说完一切,想象力丰富的人,可能感受的更多。成功,荣誉在大自然面前现的一文不值,在宇宙中人类也是渺小的生物。不自满,但是也不能丢失一个人最基本的尊严。得像一个男人一样,面对困难,人的一生总是在面对困难,这是一个注定的事实,没到困难面前我们都唯唯诺诺止步不前,那人生也不会见到新的风景。
去面对吧,去感受吧,这就是活着的意义。
