Passive Hubs
These hubs are nothing more than point contacts for the
wires that make up the physical network. An example of this
would be a punchdown block that is a simple plastic,
unpowered box used to plug network cables into it.

Active Hubs
Active hubs are a little smarter than the passive hubs we
saw. All You might also come across the
term "concentrators" which are basically active hubs,
concentrating and strengthening a signal as it enters and
exits the hub.

It's also worth noting that today's active hubs are
advertised as "hubs" or "repeaters". It is very rare you
will see a hub with the word "active" on it!

These hubs usually come in configurations of 4, 8, 16 and
24 ports, providing link & activity leds (lights) to show
which devices are currently connected, powered on and
transmitting or receiving data.

Lastly, you might be interested knowing that all Ethernet
hubs are active hubs.

a passive hub is just a connector. it connects the wires
coming from different branches.
an active hub is actually a multiport repeater. it is used
to create connections between stations in a physical star
topology.

an active hub uses electricity to amplify the signals,so is
smarter than a passive hub which doesnot use electricity and
gives the work of simply connecting different computers
physically

Active hubs process information, while passive hubs don't. Passive ones are just simple hubs that are used to connect a few devices.
