6Intranet与Extranet教学设计

1、internet对商务企业级经营的影响一、改变促销手段由原来的电视，街头广告拓展到互联网。

互联网是一个规模巨大的无形虚拟市场。

二、加剧竞争程度原来的资金，技术等将大大减少。

降低了企业的经营成本，买方的选择余地进一步扩大。

服务与价格将是无法避免的。

无形中加剧了竞争度。

三、创造企业模式电子商务创造了新的企业模式--虚拟企业。

打破了企业之间、产业之间、地域之间的界限。

管理由原来的相互控制转向相互支持，由监视转向激励，由命令转向指导。

四、调整企业规模企业规模不再是你有多大的厂房，多少员工，互联网上每个企业就是一个站点，两人管理的商城与传统的200人管理的书店没有什么区别。

五、缩短生产周期1.利用互联网快速调研市场，把握市场需求。

2.产品信息快速传播，即时获取反映，改良产品。

3.了解竞争对手产品并分析，从而调整自己的产品。

2、Internet、intranet、extranet的区别与联系区别：1、与Internet相比，Intranet在网络安全方面提供更加有效的控制措施，克服了Internet安全保密方面的不足。

2、Intranet的信息传输速度一般比Internet要快得多。

从企业或机构的角度来看，Internet 是面向全球的，而Intranet是面向各单位内部的。

主要差别在于前者强调其开放性，而后者更注重网络资源的安全性。

3、Internet和Intranet的区别在于Internet连接了全球各地的网络，是公用的网络，允许任何人从任何一个站点访问它的资源。

而Intranet是一种企业内部的计算机信息网络，是专用或私有的网络，对其访问具有一定的权限，其内部信息必须严格加以维护，因此对网络安全性有特别要求，如必须通过防火墙与Internet连接。

4、Intranet仅适用于企业内部，满足公司内部员工的信息查询，不能满足其他人员，如客户、经销商和供货商对企业内部信息的密切关注。

Extranet弥补了Intranet在与外界联系方面的不足，成了Intranet的新发展。
