HUB

Hub is a Layer 1 (physical link) device of the 7 layer OSI model. It is a common connection point for devices in a network which are used to connect segments of a LAN and can contain multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Hubs serve as central connection for all of the network equipment and handles a data type known as frames. In a hub, frames are passed along to every one of its ports to ensure that it will reach its destination. This places a lot of traffic on the network and can lead to poor network response times.
