The binary exponential backoff is a kind of countdown that starts after the NIC stops transmission and selects a random value of 0–2^n-1. The maximum value of n is 15.
a) What happens if the maximum value of n is set a little lower than 15 (3 or 4)?
b) What happens if the maximum value of n is set higher than 15 (1000 or 2000)?
c) If the range of random values is set to 0~n, which is a form of increasing by 1 rather than 0~2^n-1, what are the advantages and disadvantages?
