Internet question?

I was asked to answer the following annoyed question:


--------------------------------------...


Match the following to one or more layers of the OSI model:


a. Route determination


b. Flow control


c. Interface to transmission media


d. Provides access for the end user





e Communicates directly with user’s application program


f error correction and retransmission.


g Mechanical. electrical. and functional interface


h Responsibility for carrying frames between adjacent nodes


--------------------------------------...


can anybody help?





thanks a lot

Internet question?
Well, D matches E, B matches F, A matches H, C matches G





A: Route determination is responsible for carrying frames between adjacent nodes. Frames is packets of data and the route determines which node the data is sent and retrieved to/from.





B: Flow control includes error correction and retransmission as needed.





C: Interface to transmission media is mechanical, electrical and functional interfaces.





D and E are a bit confusing, because they fit together with all of the others at one point or another. I put them together at the top, only because they both do the same thing, theoretically speaking.





All of the others provides access for the end user *and* communicates directly with user's applications and programs.





If even one of the others fails, then access to the end user and communication for programs and applications fails. This must be a trick question. lol





Good luck and much success with your course or whatever it is you are working on, please have a nice day.
