Model answer
All three connect devices, but at different intelligence levels.
| Basis | Hub | Switch | Router |
|---|---|---|---|
| Layer | Physical (L1) | Data Link (L2) | Network (L3) |
| Sends data | Broadcasts to all ports | Sends to target MAC only | Routes by IP to other networks |
| Speed | Slow, collisions | Fast, full duplex | Connects LAN to internet |
| Example | Old 8-port hub | Office 24-port switch | ISP/home Wi-Fi router |
Office LAN uses switch for PCs; router (gateway, e.g. 192.168.1.1) links that LAN to the internet.
