什么是全球资讯网
网际网路主要的资讯交换服务。全球资讯网由伯纳斯-李和他在欧洲核子研究组织(CERN)的同僚创造出来,并在1991年引进全世界。全球资讯网让用户连至各式各样的文件,这些文件藉着超文字或超连结彼此相连。具有相关文字和超连结的超文字文件以超文字标示语言(HTML)写成,并签下一个网路地址或统一资源定位器(URL)。全球资讯网在网际网路的基本主从式架构中运作。具有独特电子位址的个别超文字标示语言档案称为网页,而共有一组类似位址的网页和相关档案(例如图档、指令程式和其他资源)合集称为网站。网站的主页或介绍页通常称为该站的首页。用户可以键入适当地址而进入任何网页,使用搜寻引擎来寻找感兴趣主题的网页,或者点按其中的超连结而在网页之间快速移动。全球资讯网虽在1991年引进,却到1993年具有图形介面的马赛克浏览器问世後才风行起来。最後,网景公司和微软公司的浏览器居於主宰地位。
World Wide Web (WWW)
Leading information-exchange service of the Internet. It was created by Tim Berners-Lee and his colleagues at CERN and introduced to the world in 1991. The Web gives users access to a vast array of documents that are connected to each other by means of hypertext or hyperlinks. A hypertext document with its corresponding text and hyperlinks is written in HTML and is assigned an on-line address, or URL. The Web operates within the Internet's basic client-server architecture. Individual HTML files with unique electronic addresses are called Web pages, and a collection of Web pages and related files (such as graphics files, scripted programs, and other resources) sharing a set of similar addresses (see domain name) is called a Web site. The main or introductory page of a Web site is usually called the site's home page. Users may access any page by typing in the appropriate address, search for pages related to a topic of interest by using a search engine, or move quickly between pages by clicking on hyperlinks incorporated into them. Though introduced in 1991, the Web did not become truly popular until the introduction of Mosaic, a browser with a graphical interface, in 1993. Subsequently, browsers produced by Netscape and Microsoft have become predominant.
