With the rapid development of internet communication and multimedia technology, people tend to think thank that the traditional applications,for example: WWW services,FTP services,Email, Telnet services etc, become to be unfit for our demands in the real life.

随着计算机网络通信技术和多媒体技术的发展，人们不再满足于传统的网络应用，如WWW服务、文件传输、电子信箱、远程登录等；现在，集音频、视频和共享数据于一身的多媒体应用已成为新型应用的热点。

Traditional Ethernet, all users share the same broadcast domain and the domain of conflict will cause a decline in network performance, the emergence of switches to solve the problem of domain conflict, while broadcast storm control and network security only through the Road achieved by the device.

传统的以太网中，所有的用户共享同一个广播域和冲突域，会引起网络性能的下降，交换机的出现解决了冲突域的问题，而对广播风暴和网络安全的控制只能通过路由器来实现。

Business electronic commerce covers include: exchange of information, pre-market after-sale (for products and services details, the use of technology products guides, answering customer opinion), marketing, electronic payment (using electronic funds transfer, credit cards, electronic chouse, and electronic cash), transport, the gradual virtual enterprises (formation of a physical, non-existent enterprises. Concentrate a number of small independent companies' competence than any single company to provide more and more products and services), companies and trading partners can share jointly owned and operated business methods, etc. In short, e-commerce is the use of existing computer hardware, software and network infrastructure. The agreement will connect through electronic network environment for a variety of business activities.

电子商务涵盖的业务包括：信息交换、售前售后服务（提供产品和服务的细节、产品使用技术指南、回答顾客意见）、销售、电子支付（使用电子资金转帐、信用卡、电子支票、电子现金）、运输、逐渐虚拟企业（组建一个物理上不存在的企业，集中一批独立的中小公司的权限，提供比任何单独公司多的多的产品和服务）、公司和贸易伙伴可以共同拥有和运营共享的商业方法等等总而言之，电子商务是利用现有的计算机硬件设备、软件和网络基础设施，通过一定的协议连接起来的电子网络环境进行各种各样商务活动的方式。

The SAN makes it true that storage resources can be devided from servers, and can provide high performance data pipe with 100 MB/s and shared storage devices managed concentrically. This makes data access, backup and restore will not reduce performance of network largely. This removes people抯 misgiving for bandwidth of network.

SAN使存储资源与服务器分离，可以提供100兆字节／秒的高性能数据管道和共享的集中管理的存储设备，使得数据的访问、备份和恢复不会大幅度降低网络性能，消除人们对网络带宽的顾虑。

Through the utilization of advanced computer technology, multimedia technologies, simulation technique, profited from the design concept of the Simens TIA, with the aid of Tomcat, Microsoft SQL Server, WinCC Web Navigator, SIMIT, this system achieved the crasis of the industrial ethernet directed net and information network, constructed a distance laboratory with remote control, monitoring, management as one, and used the JSP technical to complete the distance laboratory website.

该系统运用了先进的计算机技术、多媒体技术、仿真技术，借鉴西门子全集成自动化的设计思想，通过使用Tomcat软件、Microsoft SQL Server软件、西门子WinCC Web Navigator软件、SIMIT仿真软件等，实现了工业以太网控制网络与信息网络的融合，构建了一个集远程控制与监控为一体的远程实验室，并使用JSP技术设计完成远程实验室网站，实现了实验室信息的共享。

Based on the behavior of user in the P2P networks applications,the model has designed many attributes for every peer;some current strategies of peers selection and pieces selection are included in the model;the model has devised the interface for the underlying overlay network topology architecture.

该模型根据现实P2P资源共享系统中用户的行为的基本特点设计了Peer的各种属性，包容了现有常见的P2P资源共享应用中peers选择和pieces选择策略，并为进一步设计P2P底层覆盖网络拓扑结构提供了接口。

This text pointing out experiment is organic component of network teaching , is raise and the important foundation of guarantee network branchery education quality .

Internet的不断发展和广泛应用，为各种资源共享提供了基础，同时也为共享高校优质教学资源提供了条件。于是国家在一些重点高校相继成立了网络教育学院，开展远程学历教育。

This paper illustrates the necessity of resources co-construction and s haring system under network environment , and briefly introduces main forms of co-construction and sharing system .

阐明了网络环境下资源共建与资源共享的必要性并简要介绍了其共享的形式。

However, if auto-negotiation is disabled or not supported, the duplex must be set by auto-detection or manually on both the switch port and the device to prevent duplex mismatch, a common cause of problems with Ethernet (the device set to half-duplex will report late collision s and the device set to full-duplex will report runts).

交换网络典型的使用星型拓扑，尽管设备工作在半双工模式是仍然是共享介质的多结点网。10BASE-T 和以后的标准是全双工以太网，不再是共享介质系统。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
