The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
I would say an ethernet extender/booster/repeater.
A transducer.
Although some would suggest that a switch could segment a network (and it does use the MAC address for switching) more properly a bridge would be the answer if you are speaking of segmenting a network.
Device which are on the network and the traffic is passing thru it.
A node is a device connected to a network such as a computer or a game console. (Each device connected to a network is referred to as a node. A node can be a computer, printer, game console, or router.)
hub

a passive hub does not regenerate the signal received only let it pass

A Hub is the only network device for this type of job. Since a router stops broadcasts, it segments a network in a way. On the other hand, a switch does forward broadcasts but it creates segments because each switch port can be a network on their own.

A network ready device is a device that has the potential to connect to a network, natively it isn't connected to a network, nor is it a network, but with the appropriate configuration and possibly with the addition of components could be connected.
A router
NIC Network Card Interface is a hardware component without which a computer cannot be connected over a network. It is card or chip which contains MAC address which actually helps to identify the device on the network.
Hub is the device used to interconnect nodes in a network
