Now, create a diagram for three different types networks:
现在,为三种不同类型的网络创建一个图表:

1. LAN Local Area Network
1. LAN-局域网


2. WLAN Wireless Local Area Network
2. WLAN-无线局域网


3. WAN Wide Area Network
3. WAN-广域网

1. Hub:
1.集线器:

Imagine a hub like a big circle where everyone can talk to each other. When one person says something, everyone else hears it. Its not very smart because it sends the same message to everyone, even if they dont need to hear it.
想象一个像一个大圆圈的枢纽,每个人都可以互相交谈。当一个人说了什么,其他人都会听到,这并不明智,因为这会向所有人传递同样的信息,即使他们不需要听到。

2. Switch:
2.开关:

A switch is like a smart helper that knows who wants to talk to who. If one person wants to send a message to a specific friend, the switch makes sure only that friend hears it. Its better than a hub because it doesnt bother everyone else.
交换机就像一个聪明的助手,知道谁想和谁说话。如果一个人想给一个特定的朋友发信息,交换机会确保只有那个朋友能听到,这比集线器好,因为它不会打扰其他人。

3. Bridge:
3.桥:

Think of a bridge like a path that connects two different places. If you have two groups of friends who dont know each other, a bridge helps them share messages. It lets people from one group talk to people in another group, helping everyone connect.
把桥想象成一条连接两个不同地方的小路。如果你有两组互不认识的朋友,一座桥可以帮助他们分享信息。它可以让一个组的人与另一个组的人交谈,帮助每个人建立联系。
