Question
What is HUB ? Explain all the types of HUB.
Solution
Hubs:
(1) In some network topologies, mostly ARCNET based star topologies, a device hub is used.
(2) Hub is a connecting device in which cables can be connected without soldering wires to centralise network traffic through a single connecting point.
There are three types:
(1) Active hub (2) Passive hub (3) Switching hub
Active hub : interconnect the network and also amplifies the signal received apart from splitting and retransmitting it to the destination.
Passive hub : It only splits and transmits signal received and it can not amplify it. This do not contain any electronic component.
Switching hub : This quickly routes the signals between ports of hubs. It can be used in place of router.
