我正在准备考试,我对这个问题有点迷茫

A computer system has a RAM containing 64k bytes, each of which needs its own distinct
address.  Moreover it has 4 peripherals and they each require 2^4 distinct addresses
in order to interface properly. 

a) How many distinct addresses in total are necessary in this system? Write the total 
   number. 
对于这个问题,我得到了65600

b) Place the number of addresses just computer between the appropriate poweres of two
   in the expression on the left, by writing the correct exponent.(example: if your 
   answer is 18 you would put 2^<18<2^5.)
我在这个问题上迷失了方向

非常感谢您的帮助,我希望我用正确的标签发布了这篇文章。

对于c),您只需写17。从b)中,您知道地址需要严格大于16位,小于17位。所以很明显,16个地址行是不够的,17是可以容纳所有地址值的最小值(尽管它可以表示比您需要的更多的地址值)

c)How many lines does an address bus for this system rquire, given that it must
  be able to carry all the needed values for the address?
