Hello.  I need an answer to the following questions:

Consider a half-duplex point-to-point link using a stop-and-wait
scheme, in which a series of messages is sent, with each message
segmented into a number of frames (IP frames).  Ignore errors and
frame:

A. What is the effect on line utilization of increasing the message
size so that fewer messages will be required? Other factors remain
constant.

B. What is the effect on line utilization of increasing the number of
frames for a constant message size?

C. What is the effect on line utilization of increasing frame size? 

Thank you!

Sorry, the first part should say "Ignore errors and
frame ovehead."  Overhead got chopped off.
