计算机局部地区网络是通信技术与计算机技术相结合的产物。在英文的文献中,常见到LAN这样的称呼(代表Local Area Network)。也常见到LCN或LACN的表示法(这里C代表Computer)。预计今后“LAN”的表示法将和用“CPU”表示中央处理机一样,广泛为人们所采用。LAN有时简称为局部网络。这当然不如“计算机局部地区网络”意义明确,但大多数技术人员是清楚“局部网络”的含义的。在本文中,将尽量采用简便的称呼 Computer local area network is a combination of communication technology and computer technology. In the English literature, it is common to call LAN (on behalf of the Local Area Network). Also common to LCN or LACN notation (where C stands for Computer). It is expected that in the future “LAN” notation will be widely used by people, just as “CPU” indicates a central processing unit. LAN is sometimes referred to as a local network. This of course is not as clear as the “computer local area network,” but most technicians are aware of the meaning of “local network.” In this article, we will try to use simple call
