某位高人花5分钟也许就可以帮我大忙
关于网络的几个问题：
可否用中文简单的讲讲hub,bridge,router的主要功能，用途，以及区别？
谢谢！！

Hubs are essentially repeaters, operateing on bits.
layer 1 device;
taking an input and retransmits the input on the hub's outgoing ports.
Bridges are layer 2 devices.
using the concept of store-and-forward transmission.
interconnecting networks.
Routers are layer 3 devices.
interconnect physically different networks that support different network protocols.
store-and-forward packets using network-layer addresses. (bridge forwards packets using LAN addresses.)
不知道用中文怎么讲，你将就着看吧。
正好帮我复习一下。^-^

Just the basics:
| 类别 | Hub/Repeater | Bridge/Switch | Router |
|---|---|---|---|
| 工作层 | 物理层(Physical) | 连接层(Link) | IP层 |
| 备注 | Hub通常是指多端口的Repeater | Switch通常是指多端口的Bridge |
