According to the mode of processing, computers are either analog or digital. They can be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computers speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC, introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IVTranslate the following passage from English into Chinese.A computer system includes a computer, peripheral（外围的）devices, and software. The electric, electronic, and mechanical devices used for processing data are referred to as hardware. In addition to the computer itself, the term “hardware” refers to components called peripheral devices that expand the computers input, output, and storage capabilities. Computer hardware in and of itself does not provide a particularly useful mind tool. To be useful, a computer requires a set of instructions, called software or a computer program, which tells the computer how to perform a particular task. Computers become even more effective when connected to other computers in a network so users can share information.计算机系统包括计算机、外围设备和软件。用于处理数据的电动、电子与机械设备称为硬件。除了计算机本身之外，“硬件”这一术语还指被称为外围设备的组件，这些外围设备可扩大计算机的输入、输出和存储能力。计算机硬件本身在本质上并未提供一件特别有用的智能工具。计算机要想变得有用，就需要有称为软件或计算机程序的一套指令，来告诉计算机如何执行一项特定的任务。计算机在以下情况下变得更加有效：与网络中的其他计算机相连接，以使用户能够共享信息Section BIFill in the blanks with the information given in the text:1 display2 underwater; GUI3 intranet4 functionalityIITranslate the following terms or phrases from English into Chinese and vice versa:1 circuit board 电路板2 beta testing 测试3 thin-client computer 瘦客户机电脑4 cell phone 蜂窝电话（移动电话）5 digital video 数码摄像机，数码影视6 Pentium processor 奔腾处理器 7 virtual screen 虚拟屏幕 8 desktop computer specifications 台式计算机规格 9 radio frequency 射频 10 wearable computer 可佩带式计算机 Section CPDA Prizefight: Palm vs. Pocket PCI.Fill in the blanks with the information given in the text:1.With DataVizs Documents To Go, you can view and edit desktop documents on your PDA without converting them first to a PDA-specific _.
