(1)Abacus 算盘
The machine is quite simple, consisting of beads strung on rods that are in turn mounted in a rectangular frame. As the beads are moved back and forth on the rods, their positions represent stored values.
这台机器非常简单，由串在杆上的珠子组成，这些杆再固定在一个矩形框架中。当珠子在杆上来回移动时，它们的位置代表存储的值。For control of an algorithm’s execution, the machine relies on the human operator. Thus the abacus alone is merely a data storage system.
对于算法执行的控制，这台机器依赖于人类操作员。因此，算盘本身仅仅是一个数据存储系统。(2)Adding Machine 加法机
This device employed a series of ten-toothed wheels, each tooth representing a digit from 0 to 9, with data being input mechanically by establishing initial gear positions.
Output was achieved by observing the final gear positions.
该设备采用了一系列的十齿轮，每个齿代表0到9的数字，数据通过机械方式输入，通过设置初始齿轮位置。通过观察最终的齿轮位置来获得输出。(3)Difference Engine、Analytical Engine 差分机、分析机
Analytical Engine was designed to read instructions in the form of holes in paper cards.
分析机被设计为读取纸卡上的孔形式的指令。Thus Babbage’s Analytical Engine was programmable. In fact, Augusta Ada Byron, who published a paper in which she demonstrated how Babbage’s Analytical Engine could be programmed to perform various computations, is often identified today as the world’s first programmer.
因此，巴贝奇的分析机是可编程的。实际上，奥古斯塔·阿达·拜伦发表了一篇论文，其中她展示了如何对巴贝奇的分析机进行编程以执行各种计算，今天她通常被认为是世界上第一位程序员。Charles Babbage was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage, along with Ada Byron, is best remembered for originating the concept of a programmable computer.
查尔斯·巴贝奇是一位英国博学家。作为数学家、哲学家、发明家和机械工程师，巴贝奇与阿达·拜伦一起，最被人们记住的是提出了可编程计算机的概念。(4)Electronic Computer 电子计算机
The technology of the time was unable to produce the complex gear-driven machines of Pascal, Leibniz, and Babbage in a financially feasible manner.
当时的技术无法以经济可行的方式生产帕斯卡、莱布尼茨和巴贝奇复杂的齿轮驱动机器。But with the advances in electronics in the early 1900s, this barrier was overcome. Some researchers were applying the technology of vacuum tubes to construct totally electronic computers.
但是随着20世纪初电子学的进步，这一障碍被克服了。一些研究人员正在应用电子管技术来构建完全电子化的计算机。Atanasoff-Berry machine 阿塔纳索夫-贝瑞机
The first of these machines was apparently the Atanasoff-Berry machine, constructed during the period from 1937 to 1941 at Iowa State College by John Atanasoff and his assistant, Clifford Berry.
这些机器中的第一台显然是阿塔纳索夫-贝瑞机，由约翰·阿塔纳索夫和他的助手克利福德·贝瑞在1937年至1941年期间在爱荷华州立学院建造。
Colossus 巨人机
Another was a machine called Colossus, used by the team headed by Alan Turing to decode German messages during the latter part of World War II.
另一台是被称为巨人的机器，由艾伦·图灵领导的团队在第二次世界大战后期用来解码德国的信息。
ENIAC 电子数值积分器和计算器（考点）
Other, more flexible machines was developed, such as the ENIAC (electronic numerical integrator and calculator).
还开发了其他更灵活的机器，如ENIAC（电子数值积分器和计算器）。
(5)Integrated Circuits 集成电路
The history of computing machines has been closely linked to advancing technology, including the invention of transistors and the subsequent development of circuits constructed as single units, called integrated circuits.
计算机的历史与技术进步密切相关，包括晶体管的发明以及随后作为单个单元构建的电路的发展，称为集成电路。With these developments, the room-sized machines of the 1940s were reduced over the decades to the size of single cabinets while the processing power of computing machines began to double every two years.
随着这些发展，20世纪40年代占据整个房间的机器在几十年间缩小到了单个柜子的大小，而计算机的处理能力开始每两年翻一番。As work on integrated circuitry progressed, many of the circuits within a computer became readily available on the open market as integrated circuits encased in toy-sized blocks of plastic called chips.
随着集成电路工艺的发展，计算机内部的许多电路以集成电路的形式在公开市场上广泛可用，它们被封装在玩具大小的塑料块中，称为芯片。

Today, the term PC is widely used to refer to all those machines (from various manufacturers) whose design has evolved from IBM’s initial desktop computer. At times, however, the term PC is used interchangeably with the generic terms desktop or laptop.
今天，PC这个术语被广泛用来指代所有那些（来自不同制造商）的设计从IBM最初的台式计算机演变而来的机器。然而，有时PC这个术语与通用术语台式电脑或笔记本电脑互换使用。Internet 互联网 (考点)
As the twentieth century drew to a close, the ability to connect individual computers in a world-wide system called the Internet was revolutionizing communication.
当20世纪即将结束时，将个人计算机连接在一个名为互联网的世界性系统中的能力正在彻底改变通信方式。
A British scientist Tim Berners-Lee proposed a system by which documents stored on computers throughout the Internet could be linked together producing a maze of linked information called the World Wide Web (shortened to “Web”).
一位英国科学家蒂姆·伯纳斯-李提出了一个系统，该系统可以将存储在互联网上计算机中的文档链接在一起，形成一个称为万维网（简称为“Web”）的链接信息迷宫。
To make the information on the Web accessible, software systems, called search engines, were developed to “sift through” the Web, “categorize” their findings, and then use the results to assist users researching particular topics.
为了使Web上的信息易于获取，开发了称为搜索引擎的软件系统，以“筛选”Web，“分类”他们的发现，然后使用结果帮助用户研究特定主题。Embedded 嵌入式
As the desktop computers were being accepted and used in homes, the miniaturization of computing machines continued. Today, tiny computers are embedded within various devices.
随着台式计算机被家庭接受和使用，计算机的小型化仍在继续。如今，微小的计算机被嵌入到各种设备中。
For example, automobiles now contain small computers running Global Positioning Systems (GPS), monitoring the function of the engine, and providing voice command services for controlling the car’s audio and phone communication systems.

最近，仅仅是一部电话已经演变成为一台小型手持通用计算机，称为智能手机，其中电话功能只是众多应用之一。These “phones” are equipped with a rich array of sensors and interfaces including cameras, microphones, compasses, touch screens, accelerometers (to detect the phone’s orientation and motion), and a number of wireless technologies to communicate with other smartphones and computers.
这些“手机”配备了丰富的传感器和接口，包括摄像头、麦克风、指南针、触摸屏、加速度计（用于检测手机的方向和运动），以及一些无线技术，用于与其他智能手机和计算机通信。The potential is enormous. Indeed, many argue that the smartphone will have a greater effect on society than the PC.
潜力是巨大的。事实上，许多人认为智能手机对社会的影响将大于个人电脑。
The miniaturization of computers and their expanding capabilities have brought computer technology to the forefront of today’s society. Computer technology is so prevalent now that familiarity with it is fundamental to being a member of modern society.
计算机的小型化及其不断扩展的能力使计算机技术成为当今社会的核心。计算机技术现在如此普遍，熟悉它是成为现代社会成员的基础。
Computing technology has altered the ability of governments to exert control; had enormous impact on global economics; led to startling advances in scientific research; revolutionized the role of data collection, storage, and applications; provided new means for people to communicate and interact; and has repeatedly challenged society’s status quo.
计算机技术改变了政府行使控制的能力；对全球经济产生了巨大影响；在科学研究中取得了惊人的进步；彻底改变了数据收集、存储和应用的角色；为人们提供了新的通信和互动方式；并不断挑战社会的现状。
