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.IV(Translate the following passage from English into Chinese.A computer system includes a computer, peripheral(外围的)devices, and software.

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。

• The Analytical Engine
• Early Computers
• Electronic Computers
• Integrated Circuits
– Late in the 1960s the integrated circuit, or IC, was introduced, making it possible for many transistors to be fabricated on one silicon substrate, with interconnecting wires plated in place. The IC resulted in a further reduction in price, size, and failure rate. The microprocessor became a reality in the mid1970s with the introduction of the large-scale integrated (LSI) circuit and, later, the very large-scale integrated (VLSI) circuit (microchip), with many thousands of interconnected transistors etched into a single silicon substrate.

计算机英语第二版_清华大学_姜同强主编翻译

第1 章计算机系统概述数字计算机也称为电子计算机或计算机．它无处不在．很难发现有哪个领域没有使用计算机．在本章中．我们将介绍数字计算机、数据类型、计算机的发展和计算机分类，1 . 1 数字计算机数字计算机是处理各种计算任务的数字系统。

“数字”的意思是计算机中的信息可由具有部分离散值的变量来表示，这些离散值的内部处理是由具有部分离散状态的部件完成的．例如．十进制数字O , l , 2 ，… 9 ．即提供了10 个离散值。

第一台电子数字计算机产生于20 世纪40年代末，它主要用于数值计算，那时的离散元素即为数字．为了进行数值计算而产生了数字计算机．实际上．如果只使用两种状态．数字计算机的性能将更可靠。

因为部件的物理约束和人们的逻辑处理需要．所以数字计算机使用具有两种值的离散数据．这种数据称为二进制。

数字计算机使用只有数字O 和l 的二进制数据系统．一个二进制数字称作位．在数字计算机中用一组二进制表示信息。

应用各种编码技术．一组二进制数字不但可以表示二进制数据，而且还可以表示其他离散符号．如十进制数字或字母表中的字母．例如ASCII是用7 位二进制数字表示一个字符。

通过合理使用二进制组合和各种编码技术．可产生用于完成各种类型计算的一系列指令。

与基数为10 的十进制数相比．二进制数的基数为2 ．使用了数字O 和1 ．与一个二进制数等值的十进制数可以扩展为包含更多位的二进制数．计算机系统是由硬件系统和软件系统组成的，硬件系统由看得见、摸得着的物理设备构成．如磁盘和屏幕。

软件系统是管理计算机的无形“控制”，是运行在计算机中的所有程序，程序是指令的集台，它告诉硬件应该做什么，通常将计算机硬件分为3 个主要部分：输入和输出设备（I/O 设备）、中央处理器（CPU）和存储器。

在第2 章中对硬件部分进行详细介绍．软件可以按其用途分类。

应用软件是为诸如会计、娱乐和工程领域之类的处理任务而设计的，如果玩过计算机游戏或用字处理软件输入入过文件内容．则用户已经具有使用应用软件的体验。

Shift registers
A register capable of shifting its binary information in one or both directions is called a shift register.
The simplest possible shift register is one that uses only flip-flops.
The output of a given flip-flop is connected to the D input of the flip-flop at its right. The clock is common to all flip-flops. The serial input determines what goes into the leftmost position during the shift. The serial output is taken from the output of the rightmost flip-flop.

计算机专业英语课后答案（清华⼤学出版社第⼆版）第⼀章Computer system overview(操作系统概述)I. Pre-reading Questions1.What is a digital computer?The digital computer is a digital system that performs various computational tasks. The word “digital”implies that theinformation in the computer is represented by variables that take a limited number of discrete values. These values are processed internally by components that can maintain a limited number of discrete states. Digital computer is also called electronic computer or computer.2.Are there any differences between the binary number system and the common decimal number system?The decimal digits has ten digits: 0,1,2,,, and 9. The binary number system has two digits: 0 and 1. The binary numbers use a base 2. The decimal digits use a base 10.3.How many types of computers do you know? Name at least four of them. Computers are usually classified into four broad categories: microcomputers, minicomputers, mainframe computers and supercomputers.II Fill in the following blanks.1.Application software is designed to accomplish real-world tasks in fields.2. An 8-bit signed integer can have any value between -128 and 1273. System software controls the computer and enables it to run the hardware and applications software.4. A computer system consists of hardware system and software system .5. List four types of computers: microcomputers, minicomputers , mainframe computers,and s upercomputers .III True or False.1.
