给局部区域网下一个定义,对弄清楚网络的管理职责是非常重要的,因为它适用于很多的局部区域网。局部区域网是一种使不同装置互连而在它们之间能进行高速通信的通信系统。局部区域网很可能为私人所拥有,并工作在很有限的地理范围,诸如大楼、院校或工厂的综合设备内。就这个范围来说,一般在最长的两点之间不超过两英里。至于将来,由于技术的进步,这一距离长度将会增加,但现在我们谈的是广域网这样的场合。在局部区域网内,那些互连的装置包括计算机、终端、像激光打印机和高速绘图机那样的计算机外部设备及其它数据处理装置, Given the definition of a local area network, it is important to understand the network’s management responsibilities as it applies to many local area networks. A local area network is a communication system that enables different devices to be interconnected while enabling high-speed communication between them. It is likely that the LANs are privately owned and operate in a very limited geographical area, such as a complex of buildings, colleges or factories. In this context, there is generally no more than two miles between the longest two points. As for the future, due to technological advances, this distance will increase, but now we are talking about such a wide area network. Within a local area network, those interconnected devices include computers, terminals, computer peripherals such as laser printers and high-speed plotters, and other data processing devices,
