Its very interesting! Assuming that youd like asking a CPU what means “2” directly? Obviously it doesnt know. The numbers that CPU can deal with are binary codes. 0 and 1 are basic elements of computers machine language. Additionally, dont forget that a file named “xxx.bin” is a binary file. 任务 1 输入设备计算机的心脏CPU只能够明白数字1或者0。这真有趣！假设您想直接地问一问CPU, 2 是什么意思？它肯定不知道。CPU能够处理的数字是二进制代码。0和1是计算机的机器语言的基本元素。此外，不要忘记一个名字叫 “xxx.bin” 的文件就是二进制文件。And then, how do we interact with a computer? There are various input and output devices that can help us. We input different kinds of information into the computers. l We input letters, instruction codes by typing with keyboard, light pen and virtual keyboard on the touch screen.l We input pictures, our photographs by optical scanner.l We input images from digital camera, movie clip from DV, that means digital video camera, and a Webcam(网络摄像头) can help us greatly.l We input audio information into a computer by microphone, portable recorder pen.l And still input audio information from other audio resources, magnetic media of sound, music, pop etc.l Another input device is the mouseYou can move the mouse in screen，select objectsNormal setting is like that: single click left button select an icon or item, and quickly double click for running it. And single click right button on an item will popup a shortcut operation menu. l Under supporting by digital signal and voice recognizeing device and software, joystick, touch surface, point pen, tremendous newly created input devices are being used to take advantage of our daily life.那么我们怎样与计算机交往呢？有许多种的输入输出设备能够帮助我们。我们将不同类型的信息输入计算机。l 我们敲击键盘、使用光笔和在触摸屏上的虚拟键盘输入字符、指令代码。l 我们使用光学扫描仪输入图画、及我们的照片。l 我们从数码相机输入图像、从DV，也就是数码录像机输入电影剪辑，还有网络摄像头也给了我们很大的帮助。l 我们利用麦克风、便携式录音笔将音频信息输入到计算机。l 还可以从其他音频资源，声音、音乐、流行歌曲的磁性介质输入音频信息。l 另一个输入设备就是鼠标。你可以在屏幕上移动鼠标选择物体。其一般设置是这样：单击左键选择一个图标或者项目，快速地双击就可以运行它。而在一个项目上单击右键将弹出一个快捷操作菜单。l 在数字信号、声音识别设备和软件的支持下，游戏杆、触摸表面、点击笔等许许多多新创造的输入设备正在被使用,以便利我们的日常生活。The task of input device is to translate all these information (included character, audio and visual information, etc.) that our human beings can understand, to a digital signal codes that computer system can work with it, namely binary machine language. See the figure I made for you, the data transferred from an input device into CPU. 输入设备任务的任务是将这些我们人类能够明白的信息(包括字符、音频和视频信息等等，翻译成计算机能够进行工作的数字信号代码，即二进制机器语言。看一看我为您画的图，数据从某一输入设备传输进CPU。 Task-2 KeyboardKeyboard is the most important input deviceInformation is usually entered into a computer by typing characters with the keyboardThe keyboard is usually connected to the back of the system unit caseThere are two parts of a keyboard:l A typewriter keyboard area.l A Numeric keypad.Lets go deep into their functions:任务2 键盘键盘是最重要的输入设备。我们通常在键盘上敲入字符，将信息输入计算机。键盘一般连接在计算机后部。键盘可分为两个部分：l 字符键盘区l 数字键区让我们深入看看它们的功能：A set of character keys, the main part of keyboard for typing characters in. 字符键组，是键盘的主要部分,用来输入文字符号。Numeric keys. Exp.: Simultaneously press Shift key together to print the up symbol “”.数字键。例如，同时按下Shift键与该键,以输出上部的符号“”。 Allocation key. You can touch a little bulge on its surface to judge you finger position.定位键。您可以触摸到其表面上的小突起来确定您的指法。A set of shortcut function keys, normally from F1 to F12, different software assigned each of them different tasks.一组快捷功能键，通常是从F1到F12，不同的软件将它们每一个赋予不同的任务。 A set of navigation keys, Control the cursor or insertion point on the screen by strike one of them.一组导航键，敲击其中之一可以控制屏幕上的光标或者插入点(在屏幕上的位置)。 Enter回车键 Shift key help you toggle between the up cases and the lower cases. 上档键帮助您在大小写之间切换。 Capital Lock大写锁定键 Escape 退出键 Space back 退格键 Num Lock 数字锁定键 Control 控制 Alternate 切换 Insert 插入 Delete 删除 Home 开始位置 End 结束位置 Page Up 前进翻页 Page Down后退翻页 Print screen: Copy the screen. With Windows operation system, you can catch a picture of the whole screen, store it to the clipboard.屏幕拷贝：在Windows操作系统下面，您可以抓取整个屏幕画面，将其存在剪贴板中。 Scroll Lock 屏幕锁定 Pause 暂停 Task-3 output devicesAfter the CPU had processed the data from the input devices automatically or according to your instructions, the results need to be output. The situation is just like an excellent cook had made some delicious dishes, who will enjoy it? Yes, the two typical output devices are monitor and printer. Users can see commands you entered into the computer from screenThere are many kinds of monitors:任务 3 输出设备当CPU自动地或者按照您的指令处理完毕由输入设备输入的数据之后，其成果需要被输出。这正像一个出色的厨师已经做好了美味的菜肴，谁来享用它呢?当然两种典型的输出设备是显示器和打印机。用户可以看到可以从屏幕上看到您键入计算机的命令。这里有许多种的显示器：l CRT (cathode ray tube) monitor.l LCD (liquid crystal display) monitor.l E-books, also named as e-book readers.l Data projectors are widely used in multimedia class.l 阴极射线管显示器。l 液晶显示显示器。电子书籍，也被称为电子图书器读数器。l 数字投影仪被广泛地应用在多媒体教室中。And there are many kinds of printers:l Old type dot matrix printers.l Laser printer.l Ink jet printer. And a photo printer may be easily for your using at home.l Chain printer and plotter printer are used in industrial designing. 打印机也有许多类型：l 老式的点阵打印机。l 激光打印机。l 喷墨打印机。以及容易使用的家用的照片打印机。l 链式打印机和制图打印机在工业设计中使用。There still a lot of output devices:l Hi-fi speakers.l Headphone. l Fax machine. l Video Internet telephone. These devices are connected to a sound card in the system unit.此外还有许多输出设备：l 高保真扬声器。l 头戴式耳机与麦克风（耳麦）。l 传真机。l 互联网视频电话。该设备被连接到系统的声卡上。Task-4 Structure of Computer: A typical computer system can be approximately divided into four function blocks like bellow: 任务4计算机构成一个典型的计算机系统能够被大致地分为如下四个功能块：Inside the computer system there are CPU，memory (RAM & ROM)，diskette drivers，and power supply在计算机系统中有CPU、内存（RAM 和 ROM）、磁盘驱动器、和电源。CPU is the contro1 and data processing center of the whole computer systemYou can simply regard it as a skill cook, the only difference is just that the cook processing meat and vegetable, makes them become delicious dishes. Here meat and vegetable is the input for the cooker, and some dishes certainly are the output from the cook. Now turn back to our CPU, it can process the digital data from an input device, and output them to an output devices. And at the same time, the CPU controls the data flow on the inner Bus (总线), there are three kinds Buses used in our computer: CPU是整个计算机系统控制和数据处理的中心。您可以简单地将其认为是一个熟练的厨师，不同之处只不过是厨师加工输入给他的肉类和蔬菜，把这些变成美味的菜肴。这里肉类和蔬菜是为厨师而输入的，而这些菜肴当然是从厨师那里输出的。现在回到我们的CPU，它可以处理从输入设备来的数字数据，将其输出到某输出设备。同时CPU控制着在内部总线上的数据流动，在计算机中有三种总线：l AB, the short form of address bus.l DB, the short form of data bus.l CB, the short form of control bus.The most popular Bus to be used on a motherboard may be a PCI bus. That is peripheral components interface bus. l AB,地址总线的缩略形式。l DB,数据总线的缩略形式。l CB,控制总线的缩略形式。在主板上面最流行的总线或许是PCI总线。这就是外围设备元件接口总线。 Just like the excellent cook(厨师) we mentioned before, he must need a number of blank plates around him, which stored meats
