a passive hub does not regenerate the signal received only let it pass
Passive hubs- do not amplify the electrical signal of incoming packets before broadcasting them out to the network.
Hub is the device used to interconnect nodes in a network
passive
Those networking devices ,which not require any type of power (electricity) are called passive networking device,like passive HUB ,its does't require any type of power for working.
there are three types of hub which are following: 1. Active Hub. 2. Passive Hub 3. Hybrid Hub
A Passive Hub is just a connector. It connects the wires coming from different hubs. An active hub acts as a multiport repeater. Passive hub will not regenerate the signal but active hub will regenerate the signal ....... so active hub is better.
function as a repeater
a hub
Switch
its hub but now switches are used
in star topology , the central hub is called...... (i) active hub (ii) passive hub (iii) inactive hub (iv) live hub
