什么是计算机网络?简单地说就是:通过通信链路,将地理上分散配置而又独立的计算机和终端设备连接起来,实现多个用户资源共享的多机系统。 计算机网络的结构又称网络拓扑,它是指一个网络的线路和节点的几何排列。几种常见的网络拓扑形式是:树形拓扑;总线拓扑;星形拓扑;环形拓扑;网形拓扑。根据网络结构和性能,可以分成几种
What is a computer network? To put it simply: through the communication link, the geographically dispersed and independent computer and terminal equipment connected to achieve multiple user resource sharing multi-machine system. The structure of computer networks, also known as network topology, refers to the geometric arrangement of the lines and nodes of a network. Several common network topology forms are: Tree Topology; Bus Topology; Star Topology; Ring Topology; Mesh Topology. According to the network structure and performance, can be divided into several
