计算机专业英语教程第5版翻译（可编辑） 计算机专业英语教程第5版翻译 1 We have learned that all computers have similar capabilities and perform essentially the same functions, although some might be faster than others. We have also learned that a computer system has input, output, storage, and processing components; that the processor is the “intelligence” of a computer system; and that a single computer system may have several processors. We have discussed how data are represented inside a computer system in electronic states called bits. We are now ready to expose the inner workings of the nucleus of the computer system ? the processor 我们已经知道,所有的计算机都具有相似的能力,并且在本质上执行相同的 功能,尽管一些可能会比另一些快一点。我们也知道,一个计算机系统具有输入, 输出,存储和处理部件;处理器是一个计算机系统智能核心,并且一个计算机系统 可以有许多个处理器。我们已经讨论过如何在计算机系统内部,用被称作“位” 的电子状态来表现数据,现在我们要弄明白计算机系统的核心,即处理器,的内在 的工作方式。 The internal operation of a computer is interesting, but there really is no mystery to it. The mystery is in the minds of those who listen to hearsay and believe science-fiction writer. The computer is a nonthinking electronic device that has to be plugged into an electrical power source, just like a toaster or a lamp. 计算机的内部操作很有意思,但确实没有什么神秘可言。所谓的神秘只是存 在于那些听信传闻和相信科幻小说作家的人的意识中。计算机就是一种没有思想 的需要接通电源的电子设备而已,与烤面包机和台灯差不多。 Literally hundreds of different types of computers are marketed by scores of manufacturers [1]. The complexity of each type may vary considerably, but in the end each processor, sometimes called the central processing unit or CPU, has only two fundamental sections: the control unit and the arithmetic and logic unit. Primary storage also plays an integral part in the internal operation of a processor. These three ? primary storage, the control unit, and the arithmetic and logic unit ? work together. Let’s look at their functions and the relationships between them. 不加夸张地讲,市场上有几百种不同类型的计算机在销售.每种电脑在复杂 性上可能有很大区别,但归根结底,每种处理器,有时称为中央处理器即cpu,只 有两个基本部分:控制单元和计算逻辑单元.主内存在处理器内部操作中也是一 个不可缺少的部分.这三个部件--主内存,控制单元和计算逻辑单元--一起工作. 然我们看看它们各自的功能和它们之间的联系。Unlike magnetic secondary storage
