Question

1. as one computer generation has evolved to the next , the physical size of the CPU has often become smaller, while its speed and capacity have increased tremendously.
2. the CPU is responsible for directing most of the computer system activities based on the instructions provided.
3.Control unit only determines the movement of electronic signals between the main
memory and the airthmetic/logic unit.
4.The ALU is the functional unit that only carries out airthmetic operations based on the
operands in computer instruction words.
5.Registers in the control unit are used to keep track of the overall status of the propram that is running.
6.There are fours steps that nearly all CPUs use in their operation: fetch,decode,execute and write-back.

Answer 1

1. as one computer generation has evolved to the next , the physical size of the CPU has often become smaller, while its speed and capacity have increased tremendously.
当计算机从一代发展到下一代的时候，通常CPU的尺寸更加小巧，而同时计算机的速度与性能得到显著提升。
2. the CPU is responsible for directing most of the computer system activities based on the instructions provided.
CPU的主要功能是在给定的指令的基础上指挥大部分的系统行为。
3.Control unit only determines the movement of electronic signals between the main
memory and the airthmetic/logic unit.
控制单元的作用仅仅是决定电信号在主存储器和逻辑运算单元之间的流动。
4.The ALU is the functional unit that only carries out airthmetic operations based on the
operands in computer instruction words.
ALU 单元是基于计算机指令集给定的操作，来处理各种运算的单元。
5.Registers in the control unit are used to keep track of the overall status of the propram that is running.
控制单元中的寄存器被用来监视运行中的程序的整体状态。
6.There are fours steps that nearly all CPUs use in their operation: fetch,decode,execute and write-back.
几乎所有CPU在运行时都采取如下四个步骤：取指令，译码，执行 和 回写。

Answer 2

1.作为一代计算机已经进化到下一个,中央处理器(CPU)的物理尺寸常常变得更小了,而它的速度和能力如雨后春笋般大量增加。
2.CPU是负责指导大部分的计算机系统活动基于提供的指示。
3.　　控制单元仅决定的运动之间的电子信号为主
　　内存和airthmetic /逻辑单元。
4.　　ALU是唯一的功能单位进行的基础上airthmetic操作
　　在计算机指令操作数的话。
5.在控制单元寄存器用于跟踪的总体状况,propram正在运行。
6.有四步骤,几乎所有的cpu使用的操作:取,解码,执行并回写。
就这样，几个不会，嘻嘻

不是吧
