What is the difference between layer 2 and layer 3 in the
OSI model?
Answer Posted / santhi
layer2,datalink layer works based on mac address where as
layer3 i.e., network layer works based on ip address.layer2
sends data(frames) to the network layer. layer2 performs
error detection but not error recovery.
layer2 devices are switches,bridges.L3 devices are
routers,etc.,. switch maintains mac table internally, router
maintains routing table internally.
In L2, the devices within the same network will
communicate,but In L3 , we can communicate with other
networks also.ie., different networks communicate by using
router or L3 switches etc.,.
