Assume a disk cache hit rate (dchr) of 95% and 2 millisecond on average to access a page in cache. If the average access time to
MrRa [10]

Answer:

The answer is provided in the form of explanation

Explanation:

A page fault occurs means that the required page is not in main memory. First OS check for

page in the cache memory, if the page is present then retrieved but if not present then check for

page in main memory and if the page is not present here too then it searches for page in hard

drive. To calculate the expected time, the following formula is used:

Cache hit ratio = 95% = 0.95

Cache miss ratio = 5% = 0.05

Cache access time = 2 millisecond

The average access time of hard drive = 30 milliseconds

Expected time = Hit ratio (cache access time +memory access time) + Miss ratio (cache

access time + 2 * memory access time)

= 0.95 (2+30) + 0.05 (2+2*30)

= 0.95 (32) + 0.05(62)

=30.4 + 3.1

= 33.5 millisecond

Expected time = cache hit ratio * cache access time + (1 – hit ratio) * cache miss ratio

= 0.95*2+(1-0.95)*0.05

= 1.9025

Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the
pantera1 [17]

Answer:

The solution code is written in Python

  1. numList = [10, 20, 30, 40]
  2. for i in range(0, len(numList) - 1):
  3.    numList[i] = numList[i] + numList[i + 1]
  4. print(numList)

Explanation:

Firstly, create a sample number list, numList (Line 1)

Create a for-loop that will traverse through the array element from 0 till the second last of the element (len(numList) - 1) (Line 3)

Set the current element, numList[i], to the sum of the current element, numList[i] and the next element, numList[i+1]

Print the modified numList (Line 6) and we can see the output as follows:

[30, 50, 70, 40]

mips Write a program that asks the user for an integer between 0 and 100 that represents a number of cents. Convert that number
Mumz [18]

Answer:

Explanation:

The following code is written in python and divides the amount of cents enterred in as an input into the correct amount of quarters, dimes, nickels and pennies. Finally, printing out all the values.

import math

#First we need to define the value of each coin

penny = 1

nickel = 5

dime = 10

quarter = 25

#Here we define the variables to hold the max number of each coin

quarters = 0

dimes = 0

nickels = 0

pennys = 0

cents = int(input("Please enter an amount of money you have in cents: "))

if cents > 0 and cents <= 100:

   if cents >= 25:

       quarters = cents / quarter

       cents = cents % quarter

   if cents >= 10:

       dimes = cents/dime

       cents = cents % dime

   if cents >= 5:

       nickels = cents /nickel

       cents = cents % nickel

   if cents > 0:

       pennys = cents / penny

       cents = 0

   print("The coins are: "

       "\nQuarters", math.floor(quarters),

       "\nDimes", math.floor(dimes), "\nNickels", math.floor(nickels), "\nPennies", math.floor(pennys))

else:

   print("wrong value")
