线来源于计算机术语，是一种信号传输布线方式。

例如，一个地方有八个村庄,他们经常相互通信，所以他们有电话线。具体怎么连接,可以有以下三种方式。

第一种方法是在每个村庄之间建立一转线，以便进行直接沟通。如果A想找到B,他只需拿起电话直接拨打。这种效率很高，但成本也比较高

方法2: 8个村共同建A换乘站，所有线路连接中转站。这样,如果A想找到B，他会先打电话给中转站,然后中转站会转给B。这种方法效率较低，但与方法相比, 如

果村庄较多或距离较远，成本会更低

方法3:这类似于方案2,即8个村庄-起建一 条公共线路， 然后分别连接到这条公共线路上。同时，我们需要为这条线路聘请一名协调员, 以便在几个村庄想要同时呼叫时进行协调。这种成本在村庄较多或距离较远时是最低的，我们稍后会谈到效率

Line comes from the computer term, is a signal transmission wiring method.

For example, there are eight villages in one place, and they often communicate with each other, so they have telephone lines. How to connect, there can be the following three ways.

The first method is to establish a transfer line between each village to allow direct communication. If A wants to find B, all he has to do is pick up the phone and dial. This is efficient, but also costly

Method 2: 8 villages jointly build A transfer station, and all lines connect the transfer station. This way, if A wants to find B, he will call the transfer station first, and then the transfer station will transfer it to B. This method is less efficient, but compared to methods such as

If there are more villages or the distance is far, the cost will be lower

Method 3: This is similar to Option 2, i.e. 8 villages – build a public line and then connect to this public line individually. Also, we need to hire a coordinator for this line to coordinate when several villages want to call at the same time. This cost is lowest when there are more villages or distances, and we will talk about efficiency later
