Hubs that offer fast throughput for larger volumes of data can be more expensive than switches and they dont offer more ports than cheaper hubs. But Id certainly not count on it (or look for it, for that matter). A 10/100Mbps switch, unlike a hub, will distribute the full 10/100Mbps to each of its ports, ensuring that users always have access to the maximum bandwidth a significant benefit of a switch over a hub.
