Detailed explanation-1: -Transport layer aggregates data from different applications into a single stream beforepassing it toa) network layerb) data link layerc) application layerd) physical layerAnswer: aView AnswerExplanation: None.
Detailed explanation-2: -The rlogin command uses the TCP transport layer protocol. TCP expects to receive data in the form of a stream of bytes containing the information in the command. Therefore, rlogin sends this data as a TCP stream. Not all application layer protocols use TCP, however.
Detailed explanation-3: -To allow process-to-process communication, the transport layer uses sockets. One port number is assigned to a running process in a host system. These port numbers are used to distinguish the different processes that may be running at the same host.
Detailed explanation-4: -The transport layer module passes each segment to the network layer module, where it becomes the payload for a single IP datagram. The destination network layer module extracts the payload from the IP datagram and passes it to the transport layer module, which interprets the information as a message segment.
