什麼是全球資訊網

網際網路主要的資訊交換服務。全球資訊網由伯納斯-李和他在歐洲核子研究組織（CERN）的同僚創造出來，並在1991年引進全世界。全球資訊網讓使用者連至各式各樣的檔案，這些檔案藉著超文字或超連結彼此相連。具有相關文字和超連結的超文字檔案以超文字標示語言（HTML）寫成，並簽下一個網路地址或統一資源定位器（URL）。全球資訊網在網際網路的基本主從式架構中運作。具有獨特電子位址的個別超文字標示語言檔案稱為網頁，而共有一組類似位址的網頁和相關檔案（例如圖檔、指令程式和其他資源）合集稱為網站。網站的主頁或介紹頁通常稱為該站的首頁。使用者可以鍵入適當地址而進入任何網頁，使用搜尋引擎來尋找感興趣主題的網頁，或者點按其中的超連結而在網頁之間快速移動。全球資訊網雖在1991年引進，卻到1993年具有圖形介面的馬賽克瀏覽器問世後才風行起來。最後，網景公司和微軟公司的瀏覽器居於主宰地位。

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.
