Hubs

a network hub is a generic device used as a connection point for devices in a network. The hub is commonly used to connect segments of local area network (LAN). The hub contains multiple ports which when a packet arrives at a port, it's copied to the other ports so all the segments of the LAN can see it. Hubs are used as a central connection for networked devices and equipment that handle data. Compared to a switch a hub is less costly however it is slower at receives and sends information at different times.
