Answer: D
A hub is a device that connects two segments of a single
LAN. A hub is a repeater. It provides transparent
connectivity to users on all segments of the same LAN. It is
a level 1 device. A bridge operates at level 2 of the OSI
layer and is used to connect two LANs using different
protocols (e.g., joining an ethernet and token network) to
form a logical network. A gateway, which is a level 7
device, is used to connect a LAN to a WAN. A LAN is
connected with a MAN using a router, which operates in the
network layer.
