Hubs are classified as Layer 1 (Physical Layer)devices in the OSI model. At the physical layer, hubs support little in the way of sophisticated networking. Hubs do not read any of the data passing through them and are not aware of their source or destination. Essentially, a hub simply receives incoming packets, regenerates the electrical signal, and broadcasts these packets out to all other devices on the network.
PS: si eu am un switch 3Com cu 48 de porturi, cu manage dar lucra fara pic de problema.
