以共享资源为目的,通过数据通信线路将多台计算机互连而成的多机系统.资源共享包括共享网络中的计算机硬件、软件及数据.多台计算机通常在地域上是广为分布的.网络的节点和线路的连接方式有集中式、分布式、星形和环形等几种.集中式网络结构是有一台中心计算机与分散在各处的多台计算机相连,并由中心计算机集中控制信息的交换。即任何两台远程计算机之间的通信必须经过中心计算机进行;分布式网络则是每台计算机都有自己的网点处理机,
To share resources for the purpose of data communication lines through the interconnection of multiple computers made of multi-machine system.Resources sharing, including sharing the network of computer hardware, software and data.Multiple computers are usually widely distributed in the geographical area. Network node and line connections are centralized, distributed, star and ring several centralized network structure is a central computer connected with multiple computers scattered throughout, and centralized control by the central computer information Exchange. That is, any communication between two remote computers must go through the central computer; distributed network is that each computer has its own network processor,
