在人类即将跨入21世纪的今天,计算机技术以前所未有的速度在全世界普及,这是全球范围内的科技新潮。50年前,当第一台计算机ENIAC诞生时,被称为“计算机之父”的数学家冯·诺依曼曾预测:“全世界有4台像ENIAC这样的计算机就足够用了。”但事实上,目前全世界的计算机已超过几亿台,而且还以每年新增1亿台的速度在发展。著名科学家在预测上出现如此大的失误,正说明计算机技术的发展远远超过人们的预料。而Internet(汉译为国际互联网或因特网)的崛起和迅猛发展,则成为计算机发展史上的又一次浪潮。如今,随着多媒体枝术和网络技术的飞速发展,Internet、信息高速公路等已不再是高深莫测的高科技新名词,人们不但对此已不陌生,而且它们已实实在在地出现在我们身边,走进我们的工作、学习,并逐步走进我们的生活。且不说国内外著名报刊在Internet中发行的电子版;不说电子商贸飞速发展,每个月在Web(网络)虚拟商场中设置的摊点不下两万家,我国不少旅游景点与宾馆在WWW(万维网)上的主页已带来可喜的收益;也不说第一部电脑连续剧《THE SPOT(地点)》受到50多个国家的网络居民的欢迎。只要看看Internet首次实况转播奥运盛况,就在百年奥运的历史上写下了浓重的一笔,就像亚特兰大的热浪那样,它使人们对Internet关注的热情更为高涨。可以说,Internet使以计算机为主体的信息处理和传送进入了一个新的网络时代,正在广阔的领域里越来越深刻地影响着人们的生产和生活方式。而且,这种发展还仅仅是一个开始,有着无比广阔的前景。特别值得一提的是,自从1995年美国停止了对Internet主干网的资助后,Internet加速了商业化的步伐,真正走向了社会,这必将为其发展带来新的机遇。难怪有人把Internet称为未来信息高速公路的雏形。目前,我国的计算机网络发展也相当迅速,现已拥有了分别属于中科院、国家教委、邮电部和电子部的6个国际互联网出口。Internet在我国的发展方兴未艾。为使学员和读者朋友更好地了解和使用Internet互联网,本刊从这一期起开设因特网知识讲座,禾用问答的形式概略介绍Internet基本知识、使用方法及应用。讲座力求深入浅出,注重实用性,带你轻松地走进因特网。
As human beings are about to enter the 21st century, computer technology is popularized all over the world with unprecedented speed. This is a trendy world of technology. Fifty years ago, when the first computer, ENIAC, was born, von Neumann, a mathematician known as the “father of computers,” had predicted: “There are four computers in the world, such as ENIAC, that are sufficient . ”But in fact, there are more than a few hundred million computers in the world at present, and it is also growing at a speed of 100 million sets a year. The famous scientist made such a big mistake in forecasting that the development of computer technology far exceeded the expectation of people. The rise and rapid development of the Internet (translated into the Internet or the Internet) have become another wave in the history of computer development. Nowadays, with the rapid development of multimedia technology and network technology, Internet and information superhighway are no longer the new high-tech new term. People are no longer familiar with it, and they have actually appeared in Around us, into our work, study, and gradually into our lives. Not to mention domestic and international famous newspapers in the electronic version of the Internet; Do not say the rapid development of e-commerce, monthly Web (network) virtual mall setting no less than 20,000 stalls, many of our tourist attractions and hotels in the WWW (World Wide Web) home page has brought encouraging benefits; not to mention the first computer series “THE SPOT (location)” by more than 50 countries Internet residents welcome. Just look at the Internet for the first time live coverage of the Olympic Games, in the history of the century Olympic Games, wrote a thick stroke, like Atlanta heat, it makes people’s enthusiasm for Internet attention even higher. Can be said that the Internet to computer-based information processing and transmission into a new era of the Internet, is in a broader area more and more profound impact on people’s production and way of life. Moreover, this development is still only the beginning, with a vast prospect. In particular, since the United States stopped granting subsidies to the Internet backbone network in 1995, the Internet has accelerated the pace of commercialization and really started to move toward society. This will surely bring new opportunities for its development. No wonder some people call the Internet the prototype of the future information superhighway. At present, the development of computer networks in our country is also quite rapid. Now we have six Internet outlets belonging to the Chinese Academy of Sciences, the State Education Commission, the Ministry of Posts and Telecommunications and the Ministry of Electronics. Internet development in our country is in the ascendant. In order to make students and readers friends better understand and use Internet Internet, this issue of Internet knowledge lectures opened from this issue, Wo question in the form of a brief introduction to Internet basic knowledge, use and application. Lectures to explain profound theories in simple language, focus on practicality, take you easily into the Internet.
