what is the name of the transport layer packet - ANSWERSsegment
transport layer protocols can only offer services provided by the underlying network protocol
(t/f) - ANSWERSfalse
what are the two transport layer protocols provided by the internet - ANSWERSuser datagram
protocol, transmission control protocol
the network layer provides logical communication between hosts (t/f) - ANSWERStrue
the transport layer provides logical communiation between hosts (t/f) - ANSWERSfalse
congestion control is a service for the internet as a whole rather than individual applications
(t/f) - ANSWERSfalse
match the protocol to its characteristics - ANSWERSTCP - reliable transport protocol
UDP - connectionless protocol
UDP - unreliable data protocol
TCP - greater overhead needed
TCP - connection oriented protocol
UDP - no congestion control mechanism
The operating system assigns a port number to client UDP sockets at their creation that is not in
use by any other host (t/f) - ANSWERSfalse
, Two UDP segments with different IP source addresses but the same destination port numbers
will be sent to two different UDP sockets. (t/f) - ANSWERSfalse
match definition to term - ANSWERSDemulti. - the job of delivering the data in a transport layer
segment to the correct socket
multi. - The job of gathering data chunks at the source host from different sockets,
encapsulating each with header information to create segments, and passing the segments to
the network layer.
