What is the difference between repeater and hub

Think of them as shock absorbent and the data signal is the shock wave which gets absorbed when it reaches the terminating resistors. The coax cable can be up to meters and can contain no more than 30 nodes per segment. What you're looking at in the above picture is one segment 25 meters long with 4 nodes attached to it.

Some hubs have separate link lights and activity lights, others combine them into one where the link light will flash when there is activity, otherwise it remains constantly on. The Netgear hub which is displayed at the beginning of this page has two separate LEDs for the activity and link but the Compex hub below has only one. This little hub also contains a special BNC connection so you can connect a coax cable to it. When you do connect it, the BNC light comes on.

Notice the label at the top where they have written "8 port Ethernet Repeater". As we already have said, hubs are just simple repeaters.

This is how 2 eight port hubs would look when connected via the uplink port and how the data is replicated to all 16 ports : In the above picture you can see that Node 1 is again transmitting data to Node 6 and that every other node connected to the hub is receiving the information.

The collision light on the hubs will only light up when a collision is detected. Collision is when 2 computers or nodes try to talk on the network at the same time. When this happens, their frames will collide and become corrupted.

This technique is useful even in small networks. A wireless bridge receives a signal from your wireless router and sends it out to wired devices, thereby extending your wireless network.

This device makes it easy to expand network coverage to the far corners of your space without sacrificing wireless convenience.

The crucial difference between the hub and bridge is that the hub works on the physical layer, but the bridge operates on the data link layer of the OSI model. Both hubs and repeaters strengthen an incoming data signal by regenerating it to reach its destination.

Otherwise, the data signal will be subjected to attenuation. Attenuation is a term used to describe the gradual weakening of a data signal as it travels farther away from the transmitter.
