Book Abstract

4 分布式网络处理
一般在计算机网络中,用户可根据问题的实质和要求选择网内最合适的资源来处理,以便使问题能迅速而经济地得以解决,对于综合性大型问题可以采用合适的算法将任务分散到不同的计算机上进行处理。各计算机连成网络也有利于共同协作进行重大科研课题的开发和研究。利用网络技术还可以将许多小型机或微型机连成具有高性能的分布式计算机系统,使它具有解决复杂问题的能力,从而使费用极大降低。
5 提高系统性能价格比,易于扩充,便于维护
计算机组成网络后,虽然增加了通信费用,但由于资源共享,明显提高了整个系统的性能价格比,降低了系统的维护用,且易于扩充,方便系统维护,扩大了应用范围,提高了系统性价比。
1.2.3 网络的应用
1在科研教育中的应用
通过计算机网络,科技人员可以在网上查询各种文字和资料,可以互相交流,甚至可以在计算机网络上进行国际合作究项目。在教育方面,一方面叫以开设网上学校,实现远程授课,学生在家中或者其他任何方便的地方随时学习,而且利用多媒体技术,可以使枯燥的教学更为生动;另一方面,学生可以随时提问和讨论,实现“面对面”交流。
2 在企业网络中的应用
计算机网络可以使企事业单位和公司内部实现办公自动化,做到各种软硬件资源共享,如果将内部网络联入因特网还可以实现异地办公。企业可以通过国际互联网,搜索市场信息并发布企业产品信息,取得良好的经济效益。
3 校园网络的应用
校园网是将校园的计算机、工作站和终端,通过高性能网络连接到各种服务器上,组成分布式的网络系统,是将大中型计算机资源和其他网内资源共享的通信网络。校园网是提高教学、科研水平不可或缺的支撑环节。共亨资源是校园网最基础的应用,人们通过网络更有效地共享信息资源,并提供合作环境。
