在很忙碌的街道公路两边建筑物内有PC机,它们彼此间需要有效地传送数据,什么办法来解决最好(见图1) 方法之一,叫一个人每天跑十次把软磁盘送去。缺点是慢,还要占一个人。 方法之二,用调制解调器并通过电话线网络联接两PC来传数据。此法看起简单,但实际手续麻烦,花销也不小,还要敷线。 方法之三,在两建筑物之间,穿过公路,埋电缆,但要通过管理部门,埋电缆不仅花钱还要影响交通。

There are PCs in the buildings on both sides of a very busy street, and they need to send data efficiently to each other. What can be done to solve one of the best (see Figure 1) methods, asking a person to run a floppy disk 10 times a day? The disadvantage is slow, but also a person. Method two, use the modem and connect the two PCs through the telephone line network to transmit the data. This law looks simple, but the actual procedures for trouble, the cost is not small, but also wiring. The third method, between the two buildings, through the road, buried cables, but to go through the management department, buried cable not only cost but also affect the traffic.
