if a DATAGRAM i.e. packet size is larger then MTU then the DATAGRAM needs to be splitted in to two MTU sized packets and sent on the transmission media. and the rest of the packet needs to be filled to be with padding.
[=========] ———-> MTU
[==============] —–> DATAGRAM

now the datagram need to be splitted
so it becoms
