一、教学局域网的组网 随着信息化社会对信息交换和共享要求的增长,计算机网络已越来越广泛地应用于社会的各个领域。所谓计算机网络,实际上是把分布在不同地理位置的计算机,通过通信线路按照一定的网络协议连接起来,实现彼此之间的通信,以达到资源共享的一种系统运行方式。按计算机网络地理范围和计算机之间互连的距离划分,基本上可分为局域网络与广域网络两种。广域网涉及范围较大,一般可从几公里至数万公里,范围覆盖一个城市、一个国家乃至全世界。局域网地理范围
First, the teaching LAN networking With the information society for information exchange and sharing requirements increase, the computer network has been more widely used in all areas of society. The so-called computer network, is actually distributed in different geographical location of the computer, through the communication lines in accordance with a certain network protocol connected to achieve the communication between each other in order to achieve resource sharing of a system operation. According to computer network geographic range and the distance between the computer interconnection can be divided into two kinds of local area network and wide area network. Wide area network involves a wide range, generally from a few kilometers to tens of thousands of kilometers, covering a city, a country and even the world. LAN geographical range
