随着计算机广泛应用,特别是小型和微型计算机大量推向社会,一个组织在一幢建筑物或一群建筑物内安装有多台计算机的现象正日趋普遍。计算机网络技术既然能横跨大陆和海洋将世界范围的计算机连接起来,自然也能穿过走廊和高楼将办公室、试验室的各类计算机互连起来。如果把前一类称为远程计算机网(RCN);则可以将后一类称为“本地计算机网”(LCN-Local Computer Network)。 LCN的结构和协议的基础是分组通信,其硬件技术源于网络和计算机总线,它是分组
With the widespread use of computers, especially the mass production of small and micro-computers, it is becoming more common for an organization to have multiple computers installed in a single building or cluster of buildings. Since computer network technology can connect computers all over the world across the mainland and the oceans, it is naturally possible to interconnect various types of computers in offices and laboratories through corridors and high-rise buildings. If the former is called the Remote Computer Network (RCN), then the latter can be called the LCN-Local Computer Network. The structure and protocol of LCN is based on packet communication, the hardware technology of which originates from the network and the computer bus. It is a packet
