WHO AM I?

Over time I have been changed quite a lot.I began as a calculating machine in France in 1642.Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my " artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a " universal machine " to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop. I have been used in offices and homes since the 1970s.
These changes only became possible as my memory improved. First it was stored in tubes, then on transistors and later on very small chips. As a result I totally changed my shape. As I have grown older I have also grown smaller. Over time my memory has developed so much that, like an elephant, J never forget anything I have been told! And my memory became so large that even I couldn't believe it! But I was always so lonely standing there by myself, until in early 1960s they gave me a family connected by a network, I was able to share my knowledge with others through the World Wide Web.
Since the 1970s many new applications have been found for me. I have become very important in communication,finance and trade. I have also been put into robots and used to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Mocm and Mars. Anyhow, my goal is to provide humans with a life of high quality. I am now truly filled with happiness that I am a devoted friend and helper of the human race!


我是谁？

随着时间的流逝我改变了很多。1642年我在法国诞生时是一台计算器。虽然我很年轻，但我能简化很难的算术题。我发展的很慢，在查尔斯·巴比奇把我制成一架分析机前大约经历了将近200年的时间。我由使用穿孔卡片的操作员编程后，我能有逻辑地“思考”并能比任何人都更快地产生答案。在那个时候它被认为是一场技术革命，我的“人工智能”开始了。1936年，我真正的父亲艾伦·图灵，写了一本关于我怎样作为一台“通用机器”来解决任何数学问题的书。从那时起，我在规模和智力上迅速增长。到20世纪40年代，我有一个房子那么大，我想知道我是否能变得更大。然而，这个现实也使我的设计者担忧。随着时间的流逝，我被制作得小多了。

首先成为个人电脑，后来是掌上电脑，自从20世纪70年代我被用在办公室和家里。

这些变化只是因为我的储存器提高变得可能了。首先它被储存在电子管里，然后在晶体管上，后来在一个很小的芯片上。结果我完全改变了我的形状。当我已经长大时，我也变得更小。随着时间流逝，我的存储器发展如此大，像一头大象，我永远不会忘记我被告诉的任何事情！我的存储容量变得如此之大，以至于我自己都不能相信！但是我总是孤单地站在那里，直到20世纪60年代初，人们给了我一个用网络联成的家族。我可以通过万维网同其他的伙伴分享我的知识。

自从20世纪70年代，我的许多新的用途被发现。在通信、金融和贸易中我变得很重要。我也被放进机器人里、被用来制作移动电话还有帮助医学手术。我甚至被放入太空火箭里，被发射去探索月球和火星。无论如何，我的目标是为人类提供高质量的生活。我现在真正充满了快乐，我是人类忠实的朋友和帮助者！

A GUIDE FOR COMPUTER PHOBICS

Network Several computers connected to share information. Many businesses use companywide networks to send electronic mail and to share files.

E-mail The technological development that revolutionized the dating game. You get a personal E-mail address when you subscribe to an on-line service, so you can receive and send messages to people you know and those you want to know.

Internet A worldwide network of more than 20 million computers at educational institutions, government agencies, and corporations that offers E-mail, free computer files, and on-line chats about anything. However, unlike commercial services, nobody's really in charge, there's no central organizingt structure, and the commands can be complex.

Log on Connecting for a session on-line via modem-you call the service's computer and enter your personal password to gain access.

Download/upload Transferring information to and from your computer over a network or via modem. If your office computers are connected, you might upload a report from your computer to a colleague's. Or if you are connected to an on-line service, you can download a copy of an article to your computer.

Desktop publishing An office system made up of a personal computer, software, and a laser printer, used to produce printed text and graphics.

Laptop (or laptop computer) A portable personal computer that can be operated on the user's lap, rather than on a desk.

WYSIWYG What you see is what you get; the exact reproduction on a printer of graphics displayed on the screen of a visual display unit.

计算机入门指南

网络 几台计算机联通起来以共享信息。许多企业用公司网络发送电子邮件和共享文件档案。

电子邮件 给约会游

戏带来革命的技术发展。当你向一家联机服务企业注册登记时，你会得到一个个人电子邮件地址，这样你就可以收到信息并给你认识的和想要认识的人发送信息。

国际互联网络 一个由世界各地教育机构，政府部门和公司的两千多万台计算机组成的网络，它提供电子邮件，免费计算机文件，和关于任何话题的网上交谈。但它不像商业服务．它没有人真正负责管理，没有集中的组织结构，指令也可能很复杂。

登录 通过调制解调器做一次上网联接——你打电话给一个提供联机服务的企业的计算机并输入你的个人密码以便进网。

下载/上载 通过网络或调制解调器向你的计算机传递信息或从你的计算机向网络上的其他计算机传递信息。如果你们办公室的计算机是联通的，你可以从你的计算机里上载一份报告到你同事的计算机内。或者，如果你的计算机与一个联机服务联通了，你可以下载一篇文章到你的计算机里。

桌面出版系统 由一台个人电脑、软件和激光打印机组成的办公室系统，用来制作、打印文字和图表。

膝上电脑 一部手提式个人电脑，可以在使用者的膝头上操作而不是在书桌上。

所见即所得 你看到的就是你得到的。显示屏幕上的图表与从打印机里输出的内容完全一致。
