计算机硬件包括五个组成,其中控制器和运算器两部分组成的部件的名称叫什么?

1、减法和加法是一样的,只要加个电信号,把一个数变成负的就可以了,你看看加法器的电路图,一般“加法器”同时是“减法器”
2、乘法器和除法器：乘法器很简单,用加法器多加几次,或者增加硬件,多弄几个加法器就可以了.除法器不记得了,好像有点复杂
note：计算机硬件结构中,也不全是“只有一个加法器”,至少还有“浮点运算的加法单元和浮点乘法,浮点除法的单元”.
建议：你可以去看看“白中英”的“计算机体系结构”,上面有将,仔细读一读,还是很简单的.

连分都不给吗?
我帮你找的也挺辛苦的给个辛苦分吧
We build computer to solve problems.Early computer solved mathematical and engineering problems,and later computers emphasized information processing for business applications.T- oday,computers also control machines as diverse as automobile engines,robots,and microwave ovens.A computer system solves a problem from any of these domains by accepting input,processing it,and producing output.Fig.1-1 illustrates the function of a computer system.Computer systems consist of hardware and software.Hardware is the physical part of the system.Once designed,hardware is difficult and expensive to change.Software is the set of programs that instruct the hardware and is easier to modify than hardware.Computers are valuable because they are general-purpose machines that can solve many different kinds of problems,as opposed to special-purpose machines that can each solve only one kind of problem.Different problems can be solved with the same hardware by supplying the system with a different set of instructions.that is,with different software.undefined 翻译:计算机组成原理 计算机硬件 人们为解决问题而制造计算机.早期的计算机解决的是数学和工程问题,后来计算机着重解决商业应用中的信息处理问题.如今,计算机还用来控制如汽车发动机、机器人和微波炉等各式各样的机器.计算机系统解决上述这些领域中的任何一个问题都是通过接收输入、处理问题和生成输出来实现的.图1-1说明了计算机系统的功能.计算机系统由硬件和软件组成.硬件是系统的物理部分.硬件一旦设计完毕,要修改是困难的,并且花费也大.软件是指挥硬件的程序集合,比硬件容易修改.计算机之所以有用,是因为它们能解决很多不同类型的问题,是通用的机器.相对而言,每种专用机只能解决一类问题.通过为系统配备不同的指令系统,也就是配备不同的软件,能用同一硬件去解决不同的问题.

功能键：键盘最上边的Esc键和F1~F12键统称为功能键.Esc键用于强行中止或退出.F1~F12键在运行不同的软件时,被定义不同的功能.
功能键是由软件进行定义的,不同软件定义功能不同,但是确实同一个按键.所以键盘上功能键表示的功能不是由计算机硬件确定的,是软件来确定的.
判断题 答案是 错

《计算机英语》

CPU，大脑，负责数据的计算，计算机总价值的所在。显卡，脸部，负责画面的渲染，游戏主机的价值所在。内存，神经，负责数据的缓存，CPU工作的必须事物。主板，骨骼，负责硬件的搭建，主机内各硬件的连接。电源，营养，负责硬件的存活，一切硬件工作的基础。机箱，皮肤，负责硬件的保护，防尘防静电避免磕碰。电线，血管，负责电力的输送，我实在编不下去了啊！

前面的第一句话不是重点,仅仅是让你了解一下常识.
直接计算8G.也就是单位的换算.
8G=8×2^10M=8×2^10×2^10k=8×2^10×2^10×2^10B=8×2^30B=8×1024^3B=8589934592B

数字都是要转换为二进制机器码的,转换后,前面有个标志为,根据标志为判断该数字为正还是负.

答：运算器、控制器、存储器、输入设备、输出设备.

计算机硬件设备都要连接到主板上. 下列不属于计算机硬件的是电 .

Description
Temperature Difference from 100 (Airflow Temperature) S.M.A.R.T.parameter indicates the temperature of the air inside the Seagate and Samsung hard disk housing.The value is equal to [100 – specified by manufacturer temperature °C],which allows setting the minimum threshold.
Recommendations
This parameter is considered informational by the most hardware vendors.Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems,it does not directly indicate imminent drive failure.Regular backup is recommended.Pay closer attention to other parameters and overall drive health.
从上述英文解释来看,是指硬盘内的气流温度大概在100℃.
