A hub is a repeater, also known as a multi-port repeater. This include hubs, some transceivers and other various pieces of hardware. It also includes the Netelligent 1016, which is a 16 port 10Mbps hub (or repeater, if you would rather call it that). I've found that in older documentation, companies are more likely to call this type of hardware a repeater rather than the (today) more common name of hub. In short, the 1016 is a 16 port hub, and quite usable in a small network.
Yes, it does amplify the signal. It also amplifies anything else it sees on the line, including noise to some degree. The better repeaters do a better job of amplification. You want to limit the number of repeaters between two computers in order to limit latency and noise. By the same token, you want to reduce as much as possible the length of cable between two computers.
Bridges or switches (aka multiport bridges) actually read the incoming signal, reconstruct the packet and then create a new packet/signal to be sent out the appropriate ports. Thus, they don't amplify what is coming in, but reconstruct a new, fresh packet. They also cost more. If you have a choice between the two, choose a switch. In a small home network you won't go wrong using a hub (and you'll save $$$ too).
