整理ppt 存储在主存储器中的信息的处理由处理单元来执行。这个单元有能力进行算术运算和逻辑判断。它对从主存储器中得到的细分为字的信息进行操作，然后把新产生的信息放置在主存储器中。 The processing of the information stored in the primary memory is carried out by the processing unit. This unit has the capacity to perform arithmetic operations, and to take logical decisions. It receives information from the primary memory, subdivided in words, operates upon that information, and places the new information generated in the primary memory. The computer delivers to the user the results of a solution through the output unit. Again an information support will be used. The information supports for output can be continuous sheets of paper obtained from the printer, magnetic tapes, punched cards, microfilm, paper with drawings obtained from a plotter, etc.. It is also possible to have an output unit consisting of a screen where results can be displayed, for instance, in the form of diagrams. Sometimes, these devices can produce a ‘hard copy’ of that information if required. In general, a computer will have more than one output unit, one or more of which will be printers. 计算机通过输出单元传递解决问题的结果给用户。信息载体将再一次被使用。这些输出信息载体可能是来自打印机的连续纸张、磁带、打孔卡片、缩影胶片以及来自绘图仪的图纸等等。输出单元也可能是一个可以显示结果（例如图表）的屏幕。如果需要的话，这些装置有时能产生一个信息的“硬拷贝”。一般来说，一台计算机将有一个以上的输出单元，其中一个或者多个是打印机。 In general, a computer can perform several simple tasks. It can receive and store information, perform elementary arithmetic operations, take simple logical decisions, and deliver information. All the operations which are carried out inside a computer are controlled by its control unit. This unit is the brain of the computer, in the sense that it initiates, supervises, and directs the activities of the remaining units. Since the computer can perform large quantities of complex computation in an automatic way, it is also called an ‘electronic brain’. 大体上, 一部计算机能运行一些简单的工作。 它能接受和储存信息,执行基本的算术运算和简单的逻辑判断, 以及传递信息。在计算机中进行的所有操作被它的控制单元控制。这个单元被称为计算机的大脑，在某种意义上，它启动、管理，并且指导其他单元的工作。由于计算机能够自动运行大量的复杂计算，所以它也
