| the difference | Hub | Switch | router |
| Working level | Physical layer | data link layer | Network layer |
| Effect | Signal amplification and transmission function can connect computer networks together. | Divide a network port into multiple network ports to connect more devices; at the same time, you can manage ports and configure VLAN security management. | Connect different networks, and choose the line of information transmission. |
| Data transmission form | Electrical signal | Frames and packets | Bag |
| Port | 4/12 port | Multi-port, usually between 4 and 48 ports | 2/4/5/8 port |
| transfer method | Flooding, unicast, multicast or broadcast | First broadcast in unicast or multicast | First broadcast in unicast and multicast (depending on demand) |
| Equipment type | Non-smart device | smart device | smart device |
| Application | Local area network | Local area network | Local area network/metropolitan area network/wide area network |
| Transmission mode | Half duplex | Half duplex/full duplex | Full duplex |
| Rate | 10Mbps | 10/100Mbps, 1Gbps | 1~100Mbps (wireless) 100~1000Mbps (wired) |
| Type of address used for data transmission | MAC address | MAC address | IP address |
A full understanding of the differences between hubs, switches, and routers will help you find devices that are more suitable for your network. I hope that through the introduction of hubs, switches, and routers in this article, you can more clearly understand the differences between hubs, switches, and routers, so that you can select suitable devices for network deployment.
