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.
In a computer network, both hubs and switches connect multiple devices, but they operate differently.
Hubs are basic networking devices that broadcast incoming data packets to all connected devices. When a hub receives data from one device, it sends the data to all other devices on the network. This leads to a lot of unnecessary traffic and can result in collisions where multiple devices try to send data simultaneously. As a result, hubs create a single collision domain, which can degrade network performance.
Switches, on the other hand, are more advanced and efficient. They learn the MAC addresses of devices connected to each port and use this information to send data only to the intended recipient. This targeted approach reduces unnecessary traffic and minimizes collisions, as each port on a switch operates within its own collision domain. Consequently, switches enhance network performance and efficiency by managing data traffic more effectively.
