Questão 17
Questão
In the Dod Model, the only protocols that the Host to Host layer provide are TCP and UDP
Questão 18
Questão
TCP segment format contains a 16 bit source port and 16 bit destination port. It also contains a 32 bit sequencing number (when receiving segments) and a 32 bit acknowledgment (To request the next expected data via windowing)
Questão 19
Questão
UDP format does not sequence nor does it use any form of windowing so no acknowledgments are expected. Also it does not create a virtual circuit. The only format for UDP is a 16 bit Source port and a 16 bit destination port. It does have a 16 bit Length field and a 16 bit Checksum field along with the data.
