【摘要】：随着现在技术的发展和人们对工作生活需求的提高,互联网行业以其自身开放、共享、平等的特点,在各个行业都得到了充分发展和使用。在互联网普及之前,人们交流的方式是两周到达的书信,人们获取信息的途径是每日一版的报纸,人们娱乐的方式相对单一。但自从互联网进入传统行业中,工作生活的效率被提高几倍,成本节省了许多,人们之间的信息互通不需再等待,做出一个决策也许只要5分钟的时间。能买到的东西不再只是商场里陈列的有限种类,人们可以在互联网上可以买到个性化定制的商品。互联网正在一步步颠覆我们之前的生活工作学习方式。互联网进入传统行业也是大势所趋,目前在即时信息、电子商务等领域已相当成熟。但是在传统问题颇多的传统教育行业,互联网技术还没得到有效地使用。在中国传统教育行业中存在着许多问题,比如发达地区和偏远地区所拥有的教育资源分布不均,线下教育受时间地点影响较大等,这些目前还没有得到解决。本文提出了一种使用HTML5新技术实现的在线教育系统,HTML5是新一代的标记语言标准,跟之前的语言相比,一方面增强了浏览器Web网页的表现性能,在浏览器上实现客户端功能成为可能。另一方面增加了本地存储和数据库的应用,减少浏览器对插件的需求,如Adobe Fash。HTML5有许多丰富的标准库,本文应用WebSocket、WebRTC和Node.js技术实现了适合时代需求的新型在线教育系统。
[Abstract]:With the development of technology and the improvement of people's demand for work and life, the Internet industry has been fully developed and used in every industry with its own characteristics of openness, sharing and equality. Before the popularity of the Internet, people communicated through letters that arrived in two weeks, people got information through a daily newspaper, and people had a relatively simple way of entertaining. But since the Internet entered the traditional industry, the efficiency of work and life has been increased several times, the cost has been saved a lot, the information exchange between people need not wait any longer, a decision may take only five minutes. What can be bought is no longer just a limited variety of items on display in the mall, but also personalized goods available on the Internet. The Internet is subverting the way we used to work and study step by step. The Internet enters the traditional industry also is the general trend, at present in the instant information, the electronic commerce and so on domain already quite mature. But in the traditional education industry, where there are many traditional problems, Internet technology has not been used effectively. There are many problems in the traditional education industry in China, such as the uneven distribution of educational resources in developed and remote areas, and the large influence of time and location on offline education, which have not been solved at present. This paper presents an online education system (HTML5) based on the new technology of HTML5, which is a new generation of markup language standard. On the one hand, it enhances the performance of browser Web web pages. It is possible to implement client functions on the browser. On the other hand, it increases the application of local storage and database, and reduces the browser's demand for plug-in. For example, Adobe Fash.HTML5 has a lot of standard libraries. This paper uses WebSocket,WebRTC and Node.js technology to realize a new online education system suitable for the needs of the times.
