Explanation:
Detailed explanation-1: -What information is used by TCP to reassemble and reorder received segments? At the transport layer, TCP uses the sequence numbers in the header of each TCP segment to reassemble the segments into the correct order.
Detailed explanation-2: -Both UDP and TCP carry port number information in their headers. Both protocols also provide for a checksum field to assure data integrity, although it is sometimes not used by UDP. Finally, both TCP and UDP headers have a length field, which prevents incorrect or runt segments from circulating through the network.
