16TCP is a full duplex, ______________ protocol that uses a virtual circuit for a sesssion, and UDP is a _____________ protocol that does not provide a virtual circuit for a session.
- Aconnection-oriented, connection-less
- Bconnection-less, connection-oriented
17In the Dod Model, the only protocols that the Host to Host layer provide are TCP and UDP
- AVerdadero
- BFalso
18TCP 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)
- AVerdadero
- BFalso
19UDP 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.
- AVerdadero
- BFalso

- BPort 15 (UDP) and Port 17 (TCP)
23The Protocol field in the IP header for the Host to Host (DoD) and Transport (OSI) layers can also be using protocols aside from TCP and UDP. What are the protocols?

- BProxy Address Resolution Protocol (ARP)
- CReverse Address Resolution Protocol (RARP)
27Internet Protocol (IP) is a connection-less protocol
- AVerdadero

28What are port numbers used for?
- APort numbers are used to transfer information from one layer to another.
