(L1) How did Licklider and his team in the early 1960s experiment w/ a precursor to the Internet?
Connecting two computers over a dial up telephone line
,(L1) What is the Domain Name System design to do primarily?
Translate domain names into IP addresses
(L1) What is the architectural design of the Internet protocol stack based on?
Layers
(L1) Both the data link and transport layer protocols may provide error correction.
True
(L1) What allows for communication between application layer and transport layer?
Sockets
(L1) Which of the follow protocols belong to the application layer?
UDP
DNS
IP
Ethernet
DNS
(L1) Which two protocols belong in the transport layer?
UDP & TCP
(L1) When an application sends a packet of information across the network, this packet ravels down the IP
stack and undergoes what process?
Encapsulation
(L1) According to the end-to-end principle, where should most of the Internet's functionality/intelligence be
implemented?
At the edges of the network
(L1) What is the difference between hubs, bridges, and routers?
They operate at different layers of the IP stack.
(L2) The transport layer protocols offer a logical connection between processes only if the hosts reside in
the same network
False
(L2) A sending host receives a message from the application and encapsulates it with the transport layer
headers before passing it down to the network layer.
True
, (L2) An application running on a host can bind to multiple sockets simultaneously.
True
(L2) The identifier of a UDP socket is a tuple of destination IP address and port.
True
(L2) The identifier of a TCP socket is a tuple of source IP address and port.
False
(L2) UDP is considered more lightweight than TCP.
True
(L2) One of the functionalities that UDP offers is to increase or decrease the pace with which the sender
sends data to the receiver.
False
(L2) UDP offers basic error checking
True
(L2) Assume Hosts A,B, and C. Host A has a UDP socket with port 123. Hosts B and C each send their
own UDP segment to host A. Hosts B and C cannot use the same destination port 123 for sending their
UDP segment
False
(L2) TCP offers in-order delivery of the packets, flow control, and congestion control.
True
(L2) TCP detects packet loss using timeouts and triple duplicate acknowledgments.
True
(L2) Flow control is a rate control mechanism to protect the receiver's buffer from overflowing
True
(L2) Congestion control is a rate control mechanism to protect the network from congestion.
True
(L2) In TCP, the number of unacknowledged segments that a sender can have is the minimum of the
congestion window and the receive window.
