Read the following topic then explain Where a datagram can be fragmented? Where the fragmented datagram can be reassembled?

Fragmentation of Datagram Packets used by the IP are called datagrams. For a networks with a smaller MTU, we must divide the datagram to make it possible for it to pass through these networks. This is called fragmentation. A datagram can be fragmented by the source host or any router in the path. The reassembly of the datagram is done only by the destination host.
