Answer Posted / tarun tomer
Routers works at layer 3 of OSI layer model called network
layer.
Switches;
1900 series to 2960 series swiches work on layer 2(datalink
layer) of OSI models
but above 3500 series to 6500 series swiches called multi
layer swithes work on both Layer 2(data link) and layer
3(network) of OSI reference model.
