Chapter 5 Computer Memory: Integers It is time to go back to the machine level and look a little more deeply at memory. At a high level, computer memory may be categorized according to concepts such as access speed and size. Definite patterns emerge: Access Type Speed Register Fastest Caches Very fast RAM Fast Hard disks Slow Proximity to CPU Inside Adjacent Near Far Size Volatile 10’s Y 100’s to MB Y GB Y TB N At a lower level, the question is, how is data actually stored in computer memory? In this chapter, we begin to develop an answer by looking at how integers are stored.

Your program should use as few guesses as possible. You do not need to write any functions other than main(). 12 to add these features: (a) Allow the user to play more than once. (b) Report the total number of guesses taken after each round. (c) Allow the user to specify the upper limit, instead of always using 100. (d) Have your program sound confident by predicting the maximum number of guesses it will take. The log() and ceil() functions from the math module may be helpful. py that calculates the number of years it will take to reach a savings goal given a starting principal and interest rate.
