Question

Well Network Layer switch is called Router. This is little confusing.. ( Link layers switch is called bridge :P )

Answer 1

devices  layers at which they work

repeater-->phy layer

hub-------->phy layer

switch--->phy+data link

bridges---->physical layer+data link layer

router------>physical+data link +network layer.

as data link layer uses MAC address

and router uses both MAC address and logical(IP address)

so answer is both switch and bridge

Answer 2

When switch is mentioned, it refers to L2 device only. L3 switch term came late when the switches started coming with routable configs. It's not a proper official term.
