Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. Accordin
5、g to the mode of processing, computers are either analog or digital. They can also 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,
6、 and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in whic
7、h 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
8、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.IV. Translate the following passage from English into Chinese:计算机将变得更加先进，也将变得更加容易使用。语音识别的改进将使计算机的
9、操作更加容易。虚拟现实，即使用所有人类官能与计算机进行交互的技术，也将有助于创建更好的人机接口。人们正在开发其他的奇异计算模型，包括使用生物机体的生物计算、使用具有特定属性的分子的分子计算，以及使用遗传基本单位DNA（脱氧核糖核酸）存储数据和执行操作的计算。这些都是可能的未来计算平台的例子，而它们迄今还能力有限或完全属于理论范畴。科学家们研究它们，是因为嵌入硅中的电路的微小型化受到物理限制。还有一些限制与甚至最微小的晶体管也会产生的热量有关。Unit Two: Computer ArchitectureUnit Two/Section AI Fill in the blanks with th

13、the following list, making changes if necessary:CD-ROM stands for compact disc read-only memory. Unlike floppy and hard disks, which use magnetic charges to represent 1s and 0s, optical discs use reflected light. On a CD-ROM disc, 1s and 0s are represented by flat areas and bumpy (高低不平的) areas (call
14、ed “pits”) on its bottom surface. The CD-ROM disc is read by a laser that projects a tiny beam of light on these areas. The amount of reflected light determines whether the area represents a 1 or a 0.Like a commercial CD found in music stores, a CD-ROM is a “read-only” disc. Read-only means it canno
15、t be written on or erased by the user. Thus, you as a user have access only to the data imprinted (压印) by the publisher.A single CD-ROM disc can store 650 megabytes (兆字节) of data. That is equivalent to 451 floppy disks. With that much information on a single disc, the time to retrieve or access the
16、information is very important. An important characteristic of CD-ROM drives is their access rate.IV. Translate the following passage from English into Chinese:调制解调器是在模拟和数字信号之间进行转换的设备。计算机使用的是数字信号，这种信号由离散单元组成，通常用一系列1和0表示。模拟信号是连续变化的；声波就是模拟信号的一个例子。调制解调器经常用于实现计算机之间通过电话线的互相通信。调制解调器将发送端计算机的数字信号转换成可通过电话线传输的模拟信号。信号到达目的地后，另外一个调制解调器重构原来的数字信号，供接收端计算机处理。如果两
