Hubs and switches both are networking devices.
That’s means both are used to connect multiple devices within a local area network.
But some major difference between them are –
1 . Hub operate at physical layer while switch operate at data link layer.
So that hubs doesn’t differentiate between data packets.
2. Hubs support half duplex but switches support full duplex. So switches send data only to the specific device for which the day is intended but hub send data to all devices.
3. In hubs collision domains is single but in switches each ports has its own collision domains.
4. Hub is cheaper than switches because switches has some additional functionality.
5.hub s has not maintained MAC address table but switches maintain a MAC address table.
