We are using a special keyboard that allows for both polling and interrupts, and would like to determine whether polling or interrupts is better. Through analysis, we have determined that we type at an average rate of 5 characters/second, but sometimes we end up typing two characters near-simultaneously, with only 10 microseconds between inputs. We have also determined that our system runs at a 100 MHz clock frequency our computer is really really slow), and our OS/program runs with Y=400, Z=9600. We want to ensure that all characters we type are successfully captured, assuming that at least 10 microseconds elapse between keystrokes. 2a. What is the maximum value of X that allows polling to work? integer
2b. If we decide to use polling with the maximum X we determined in 2a, what is the fraction of our clock cycles that we spend polling? number (stol-0.01, atol=1e-08)
2c. Over 100 seconds, what is the average number of cycles spent running interrupts, if we decide to use interrupts? integer
2d. If we decide to use interrupts, what is the fraction of our clock cycles that we spend handling interrupts? number (rtol=0.01, atol=14-08)

Create a class hand in its own module. one object of class hand represents a hand of cards and so one object stores a number of card objects. for this assignment you will submit three separate modules, one with the definition of class card, one with the definition of class hand and one with the main application that thoroughly tests class hand.class hand must contain the following four methods: 1) , numcardsinhand) takes an integer as parameter and initializes a hand object with numcardsinhand card objects inside it. these card objects are generated randomly. for simplicity, assume an infinite number of decks of cards.2) bjvalue(self) returns the blackjack value for the whole hand of cards3) ) returns a string containing all the cards in the hand4) hitme(self) adds one randomly generated card to the handcreate a main program in its own module that thoroughly tests class hand. you will have three modules/files to upload to your etudes assignment submission: card.py, hand.py and the module that contains your main program.two alternatives for extra credit - you cannot get credit for both! (+1 point): after you have thoroughly tested the class hand and all of its methods, add code to your main program that stores one hand object as a pickle file and reads it back into a new hand object. you are only eligible for this extra credit if class hand has all four of the methods above working.or(+2 points): after you have thoroughly tested the class hand and all of its methods, add code to your main program that stores one hand object as a text file on the disk and reads it back into a new hand object. you are only eligible for this extra credit if class hand has all four of the methods above working.notes: -start by making any and all modifications suggested by my comments to your previous submission of class card from assignment #6 "a robust card object"-once your class card is tested and working well, you will not make any further modifications to it for the purposes of class hand.-you can keep the test code for class card intact. if it is indented inside an if __name__ == "__main__", then it will not be executed when your main program's module imports it.-to save time, write and test one method for class hand at a time.-under no circumstances are you to attempt the extra credit until you are completely finished with writing and testing all the methods in class hand.
