Hub works when a computer sends information to the hub, it duplicates the data to all the other interfaces. It works like this, comes in clones come out it comes in clones. The hub doesn’t know anything about packets, it doesn’t even care who will send the data, the hub will just spam everyone.

• Half-duplex
• Wastes Bandwidth
• Causes unnecessary traffic.

• It amplifies the signal.
• It does not increase or decrease the network traffic.
• Repeaters can be used in different mediums for reception and transmission.

The switch works when we always start with an empty switch array because the switch needs to know where everything is. It can act like a hub and lets everything through, but it learns by looking at the MAC address.

• Repeaters do not perform filtering of the data.

• Full-duplex
• Keeps a record of MAC Address
• Prevents Bandwidth Waste
• Increases network size

Bridges work by dividing a LAN into segments and help the hosts send and receive data to the specific segment where the receiver or another host belong. Bridges can also work by connecting LANs that work on the same protocol.

is a combination of bridge and
router.
It can forward data between
networks (serving as a bridge),
but can also route data to
individual systems within a
