Difference between Hub and Switch

Computer EngineeringComputer NetworkMCA

Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need.

Following are the important differences between Hub and Switch.

Sr. No.KeyHubSwitch
1ObjectiveHub main objective is to transmit the signal to port to respond where the signal was received.Switch enables connection setting and terminating based on need.
2LayerHub works in Physical Layer.Switch works in Data Link Layer.
3Transmission TypeHub uses broadcast type transmission.Switch uses unicast, multicast as well as broadcast type transmision.
4PortsHub can have maximum 4 ports.Switch can have 24 to 28 ports.
5Collision DomainHub has a single collision domain.In Switch, each port have their own collision domain.
6Packet FilteringHub do not provide packet filtering.Switch provides packet filtering.
7Transmission ModeHub uses half duplex transmission mode.Switch uses full duplex transmission mode.
