| HUB | SWITCH |
| A hub is a networking device that allows multiple devices to connect to a single network.. | A switch is a networking device that connects various devices on a single network. |
| Hub is a physical layer device, which means it operates at OSI model layer 1. | A switch is a data link layer device, which means it operates at OSI model layer 2. |
| Hub is a passive Device (Without Software) | A switch is a networking and active device (with software). |
| Hub uses broadcast-type transmission. | The switch uses unicast, multicast as well as broadcast-type transmission. |
| Half-duplex communication is supported by a Hub, which means that only one device can send or receive data at a time. | Full-duplex mode is supported by the switch, which means both devices can send and receive data at the same time. |
| Hub has 4/12 ports. | A switch can have 24 to 48 ports. |
| There is only one collision domain in Hub. | Each port in Switch has its collision domain. |
| A network hub cannot learn or store a MAC address. | Switches use content-accessible memory CAM tables. |
| Hub does not provide packet filtering. | A switch provides packet filtering. |
| Hub is not an intelligent device as it sends the message to all ports. | A switch is an intelligent device as it sends the message only to the desired destination. |
| For data transmission, the hub uses electrical signals or bits. | For data transmission, a switch uses frames and packets. |
| Hub speed is up to 10 Mbps | Switch speed is up to 10/100 Mbps, 1 Gbps. |
