Does an application layer act as an interface between application programs?P33
Yes
What presents data to the application layer and is responsible for data translation and code formating?P33
Presentation layer
What is responsible for setting up,managing, and tearing down sessions between Presentation layer entities?P33
Session layer
The session layer coordinates communication between systems and servers to organize their communication by offering what different modes?P33
Simplex, half duplex, and full duplex.
What is the Application layer?P32
It coordinates partnering applications and forms a consensus on procedures for controlling data integrity and error recovery.
What is the Transport layer?P33
It is responsible for providing the mechanisms for multiplexing upper layer applications ,establishing virtual connections, and tearing down virtual circuits.
Reliable networking relates to the means that acknowledgments,sequencing, and flow control will be used for what?P34
Transport layer
A sender’s TCP process contacts the destination’s TCP process to establish a connection and this resulting creation is known as a ——- —–?P34
Virtual circuit
A typical reliable session taking place between sending and receiving systems of the hosts’ application programs begin by notifying their individual operating system that a connection is about to be initiated. What is this called?P34
Connection Oriented communication
What is the three way handshake?P35
Synchronize, Synchronize acknowledgment, and acknowledgment.
What is Flow Control related to data transport between system? Select all that apply? a. segments delivered are acknowledged back to sender. b. segments not acknowledged are retransmitted. c. segments are sequenced back int their proper order upon arrival at their destination. d. manageable data flow is maintained in order to avoid congestion. e all of the above
