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
Answer:
"The holographic versatile disc".
Explanation:
According to my research on optical disk technology, I can say that based on the information provided within the question the technology being described in the question is called a "The holographic versatile disc".
Unfortunately it is not shown as an available answer but it is the correct answer. This is the only optical disk technology capable of holding 3.9 terabytes of data as well as meeting the specs mentioned in the question.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
The solution code is written in Python
- numList = [10, 20, 30, 40]
-
- for i in range(0, len(numList) - 1):
- numList[i] = numList[i] + numList[i + 1]
-
- 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]
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")
