on every transmission media there is a MTU size i.e the maximum size of data packet that can be transferres on that media.
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
[========] + [=====!!!!] where ‘!’ is padding.
