Hub

Hub is a Layer 1 (physical link) device of the OSI model. A hub connects multiple Ethernet devices together to make them act as a single network segment. It is normally used to connect segments of LAN. A hub has multiple ports. When a packet arrives at one port, it is copied to the other ports, so all segments of the LAN can see the package.

When you're connected to a hub, you are connected in half-duplex mode. That means that you can send information or you can receive information, but you can't do both at the same time.
