网络技术已渗透到社会生活的每一个角落。WWW的出现产生了HTML。在WWW中发布HTML文档,大多数信息还是静态的,而且要求服务器响应用户的交互。后来出现了DHTML语言。虚拟现实是计算机模拟的三维环境,用户可以走进这个环境并操纵系统中的对象。虚拟现实最重要也是最诱人之处是其实时性和交互性,这样出现了VRML语言。电子商务在互联网的广泛应用又产生了XML。网络继续以很快的速度在发展,将来的网络会以比现在的网络文档更灵活的方式提供更多的信息。

Publish HTML documents in the WWW, most of the information is still static, and require the server to respond to user interaction. Later appeared DHTML language. Virtual reality is a three-dimensional environment of computer simulation, the user can enter this environment and manipulate the object in the system. The most important and most fascinating aspect of virtual reality is its real-time nature and interactivity, which gives rise to the VRML language. The widespread use of e-commerce in the Internet has generated XML. The web continues to evolve at a rapid rate, and future webpages will provide more information in a more flexible way than current Web documents.
