network but we cant able to send a particular data to a
particular host.It is a layer 1 device uses to send datas
in the form of bits and it uses hardware address to send
bits
SWITCH-it is a bridge which has higher number of ports, it
is a layer two device which uses hardware address(MAC
address)to send datas in the form of frames.
