计算机网络通常是由计算机与通信相结合而形成的系统.计算机与通信也都是系统,它们既可能是一个相对独立的系统又可能是计算机网络这个更大系统中的一个要素——一个子系统,所以计算机网络系统与通信、计算机之间存在着既有联系又有区别的复杂关系.它们在技术上、结构上和功能上正在相互影响、相互结合、相互渗透,并有进一步溶合的趋势.本文将侧重对计算机网络与通信的关系进行一些分析. A computer network is usually a system formed by a combination of computer and communication.Computer and communication are also systems, either as a relatively independent system or as a component of a larger system of computer networks - a subsystem , So there are both complex and complex relations between computer network system and communication and computer.They are technically, structurally and functionally interacting with each other and interact with each other, and there is a tendency of further fusion This article will focus on the analysis of the relationship between computer networks and communications.
