Hub is not an intelligence device. It works as a multiport repeater-type network device. That’s mean it connects multiple devices that come from different branches. One of the good examples, in the start topology Hub, can connect all the devices.

hub is used in which layer of osi model
Hub is used in the Physical layer of OSI model
As it is not intelligent, that’s why Hub can not filter data, so hub sends data packets to all devices which connected.
hub is used in which topology
Hub is used in star topology.
in which topology hub is used
In Star topology hub is used.
a hub operates at which layer
A hub operates at physical layer on OSI mode
if all devices are connected to a central hub then topology is called
if all devices are connected to a central hub then topology is called Star topology.
