随着网络技术渗透到社会生活的各个方面，传统的交流方式也面临着变化。互联网是一个非常重要的方向。基于Web技术的网络考试系统可以在全球范围内使用互联网，可以在本地或异地进行通信，大大提高了通信和交换的灵活性。在当今高速发展的互联网时代，博客已经成为人们不可或缺的一部分。互联网日志，翻译博客或博客的博客通常是个人管理的，不定期发表新文章的网站。博客的文章通常按照从新到旧的顺序排列，很多博客集中于提供对特定主题的意见或新闻，其他博客则用作个人日记。一般博客包括文本、图像、结合其他博客或网站的链接和与主题相关的其他媒体。让读者以互动方式留下评论的能力是许多博客的重要因素。大部分博客内容主要是文本。博客是社交媒体网络的一部分。
博客在中国的发展始于1998年，但直到2000年才真正流行起来。2000年博客进入中国，迅速发展起来，但平淡无奇。直到2004年木子美事件，中国人才理解和使用博客。2005年，不看好博客的新浪、搜狐等国内网站也加入博客阵营，开始进入博客的春秋战国时代。博客比电子邮件和讨论组更简单，因此成为家庭、部门、公司和团队越来越广泛使用的交流工具。
