  • identifying the proper application for each communication stream
  • tracking the individual communication between applications on the source and destination hosts
  • providing frame delimiting to identify bits making up a frame
  • performing a cyclic redundancy check on the frame for errors
  • providing the interface between applications and the underlying network over which messages are transmitted
Answers Explanation & Hints:

The transport layer has several responsibilities. The primary responsibilities include the following:
Tracking the individual communication streams between applications on the source and destination hosts
Segmenting data at the source and reassembling the data at the destination
Identifying the proper application for each communication stream through the use of port numbers
