ANSWER :
A Router "routes" data from networks. Does not store frames.
A Gateway "connects" dissimilar networks.
A Repeater "extends" the signal, and doesn't have the intelligence to store frames or extend the network.
A Bridge is a device that extends or amplifies the network and more importantly has the ability to store frames, acting as a storage and forward device.
