Answer:
480,026ns
Explanation:
the time it would take to access word = 20ns
time coipied in cache = 60 ns
20ns +60ns = 80ns
this is the time to acess from main memory
it takes 12ms to move memory word to main memory
1ms is 1000000
so 12ms = 12000000ns
1200000+20+60
= 12000080 nanoseconds
hit ratio = 0.9(cache)
hit ratio = 0.6 (main memory)
miss rate = 0.1
probability of word being in main memory
= 0.1 * 0.6
= 0.06
the hit ratio of disk = 1
prob = 0.1 * 0.4 * 1 = 0.04
.1 = miss rate of cache
.4 = miss rate of main memory
1 = hit ratio of hard disk
In cache with prob 0.9, total ns = 20
in main memory prob = 0.60, total ns = 80
in hard disk prob = 0.04, total ns = 12000080ns
average time = [pr(cache)*access time] + [pr(main memory)*access time] + [pr(hard disk)*access time]
= (0.9*20)+(0.06*80)+(0.04*12000080)
= 18+4.8+480,003.2
= 480,026 ns

what is the correct process for setting up a recurring project for the same client in qbo accountant?
Answer:
The answer is below
Explanation:
The correct process for setting up a recurring project for the same client in Quickbooks Online Accountant is as follows:
1. Go to Work, then select create a project
2. Select the Repeat button, then set the frequency and duration
3. Formulate the project and save it.
4. Reopen the project
5. And select the Duplicate button for the proportion of times you want it to recur. This includes assigning the interval, day of the recurrence, and end time.
6. Then select Save.
Firstly, invent a separate project, then pick the repeat button on the right of the screen, specify the frequency and duration. Its frequency can indeed be weekly, biweekly, monthly, and so on.
This project's duration must be determined. This step saves the user time when working on a project. Otherwise, the same actions would have to be done again and over, which would be time-consuming and repetitive.New project and click the continue option to start the process of preparing a recurring project for the same client.This second alternative is not the best method to create a recurring project for the same client. Based on the phase, the initiatives can be generated as many times as necessary.Therefore, the answer is "first choice".

Write a function called combineArrays(int[], int, int[], int) that accepts in two arrays of ints and the size of the arrays as parameters. The function should then create a new array that is the size of both array combined. The function should copy the elements from the first array into the new array, followed by all the elements from the second array. So if the initial array is {1,2,3,4,5} and the second arrray is {10,20,30} then the new array will be size 8 and contain {1,2,3,4,5,10,20,30}. Then in your main(), create two arrays of different sizes, each at least size 10, and fill them with integers's. Run the arrays through your function created above and print out all three arrays to demonstrate that the concatenation method worked. Then run your method again using the same two original arrays, but in the other order. So if the first time you did array a then array b, the second time do array b then array a. Make sure to delete the new arrays before closing your program.
Answer:
The function in C++ is as follows:
void combineArrays(int arr1[], int len1, int arr2[], int len2){
int* arr = new int[len1+len2];
for(int i =0;i<len1;i++){
arr[i] = arr1[i]; }
for(int i =0;i<len2;i++){
arr[len1+i] = arr2[i]; }
for(int i=0;i<len1+len2;i++){
cout<<arr[i]<<" "; }
delete[] arr; }
Explanation:
This defines the function
void combineArrays(int arr1[], int len1, int arr2[], int len2){
This creates a new array
int* arr = new int[len1+len2];
This iterates through the first array.
for(int i =0;i<len1;i++){
The elements of the first array is entered into the new array
arr[i] = arr1[i]; }
This iterates through the second array.
for(int i =0;i<len2;i++){
The elements of the second array is entered into the new array
arr[len1+i] = arr2[i]; }
This iterates through the new array
for(int i=0;i<len1+len2;i++){
This prints the new array
cout<<arr[i]<<" "; }
This deletes the new array
delete[] arr; }

1. What is the difference between computer organization and computer architecture? 2. What is an ISA? 3. What is the importance of the Principle of Equivalence of Hardware and Software? 4. Name the three basic components of every computer. 5. To what power of 10 does the prefix giga- refer? What is the (approximate) equivalent power of 2? 6. To what power of 10 does the prefix micro- refer? What is the (approximate) equivalent power of 2?
Answer:
1.Computer Organization is how operational parts of a computer system are linked together. Computer architecture provides functional behavior of computer system. ... Computer organization provides structural relationships between parts of computer system.
2. An ISA, or Individual Savings Account, is a savings account that you never pay any tax on. It does come with one restriction, which is the amount of money you can save or invest in an ISA in a single tax year – also known as your annual ISA allowance.
3. The principle of equivalence of hardware and software states that anything that can be done with software can also be done with hardware and vice versa. This is important in designing the architecture of a computer. There are probably uncountable choices to mix and match hardware with software.
4.Computer systems consist of three components as shown in below image: Central Processing Unit, Input devices and Output devices. Input devices provide data input to processor, which processes data and generates useful information that's displayed to the user through output devices.
5.What is the (approximate) equivalent power of 2? The prefix giga means 109 in the SI (International System of Units) of decimal system. Now convert to binary definition. So, the 1 giga =230 bytes.

Answer:
7
Explanation:
#include <stdio.h>
int max2(int x, int y) {
int result = y;
if (x > y) {
result = x;
}
return result;
}
int max3(int x, int y, int z) {
return max2(max2(x,y),z);
}
int main() {
int a = 5, b = 7, c = 3;
printf("%d",max3(a, b, c));
printf("");
return 0;
}
Hi, first of all, next time you post the question, it would be nice to copy and paste like above. This will help us to read the code easily. Thanks for your cooperation.
We start from the main function:
The variables are initialized → a = 5, b = 7, c = 3
max3 function is called with previous variables and the result is printed → printf("%d",max3(a, b, c));
We go to the max3 function:
It takes 3 integers as parameters and returns the result of → max2(max2(x,y),z)
Note that max2 function is called two times here (One call is in another call actually. That is why we need to first evaluate the inner one and use the result of that as first parameter for the outer call)
We go to the max2 function:
It takes 2 integers as parameters. If the first one is greater than the second one, it returns first one. Otherwise, it returns the second one.
First we deal with the inner call. max2(x,y) is max2(5,7) and the it returns 7.
Now, we need to take care the outer call max2(7, z) is max2(7, 3) and it returns 7 again.
Thus, the program prints 7.

Explanation:
Consider an allocator on a 32-bit system that uses an implicit free list. Each memory block, either allocated or free, has a size that is a multiple of four bytes. Thus, only the 30 higher order bits in the header and footer are needed to record block size, which includes the header and footer and is represented in units of bytes. The usage of the remaining 2 lower order bits is as follows: bit 0 indicates the use of the current block: 1 for allocated, 0 for free. bit 1 indicates the use of the previous adjacent block: 1 for allocated, 0 for free Below is a helper routine defined to facilitate the implementation of free (void *P). Which option, if any, will complete the routine so that it performs the function properly?\
Note: "size" in the answers indicates the size of the entire block /* given a pointer to a valid block header or footer, returns the size of the block */
int size(void *hp)
{
int result;
__________;
return result;
}
1. result=(*(int *)hp)&(-7)
2. result=((*(char *)hp)&(-5))<<2
3. result=(*(int *)hp)&(-3)
4. result=(*hp)&(-7)
5. None of these
Answer:
result=(*(int *)hp)&(-3)
Explanation:
The result above would release the pointer or address of the integer data type with 3 memory blocks needed by the allocator.

Write a program that asks the user to guess the next roll of a six-sided die. Each guess costs $ 1. If they guess correctly, they get $ 100.00. The player will start out with a $10.00 bank. Each time he (or she) guesses incorrectly you will subtract $1.00 from their bank. Each time they guess correctly, you add $10.00 to their bank. Print the total winnings or losses at the end of the game. You can simulate the toss of the dice using the RandomRange function (Don't forget to Randomize).
Answer in python:
import random
money = 10
winnings = 0
def main():

Write the function evens which takes in a queue by reference and changes it to only contain the even elements. That is, if the queue initially contains 3, 6, 1, 7, 8 then after calling odds, the queue will contain 6, 8. Note that the order of the elements in the queue remains the same. For full credit, no additional data structures (queues, stacks, vectors, etc.) should be used. Assume all libraries needed for your implementation have already been included.
Answer:
Explanation:
The following code is written in Java it goes through the queue that was passed as an argument, loops through it and removes all the odd numbers, leaving only the even numbers in the queue. It does not add any more data structures and finally returns the modified queue when its done.

Write a program that reads a length in feet and inches (example: 3 ft and 2 in) and outputs the equivalent length in meters and centimeters example: 1.5 m and 22 mm). Use at least three functions: one for input, one or more for calculating, and one for output. Include a loop that lets the user repeat this computation for new input values until the user says he or she wants to end the program. There are 0.3048 meters in a foot, 100 centimeters in a meter, and 12 inches in a foot.
Answer:
In Python:
def main():
repeat = True
while(repeat):
feet = int(input("Feet: "))
inch = int(input("Inch: "))
Convert(feet,inch)
again = int(input("Press 1 to tryagain: "))
if again == 1:
repeat = True
else:
repeat = False
def Convert(feet,inch):
meter = 0.3048 * feet
cm = (inch/12) * 0.3048 * 100
printOut(meter,cm)
def printOut(meter,cm):
print("Meter: %.3f"%(meter))
print("Centimeter : %.3f"%(cm))
if __name__ == "__main__":
main()
Explanation:
The main function is defined here (used for input)
def main():
This sets boolean variable repeat to true
repeat = True
This loop is repeated until repeat = false
while(repeat):
The next two lines get the input from the user
feet = int(input("Feet: "))
inch = int(input("Inch: "))
This calls the convert function to convert the units respectively
Convert(feet,inch)
This prompts the user to tryagain
again = int(input("Press 1 to tryagain: "))
If yes, the loop is repeated. Otherwise, the program ends
if again == 1:
repeat = True
else:
repeat = False
The Convert method begins here (used for calculation)
def Convert(feet,inch):
This converts feet to meter
meter = 0.3048 * feet
This converts inch to centimeter
cm = (inch/12) * 0.3048 * 100
This calls the printOut function
printOut(meter,cm)
The printOut method begins here (used for printing)
def printOut(meter,cm):
These print the converted units
print("Meter: %.3f"%(meter))
print("Centimeter : %.3f"%(cm))
The main function is called here

ROCK-PAPER-SCISSORS Write a program that plays the popular game of rock-paper-scissors. (A rock breaks scissors, paper covers rock, and scissors cut paper). The program has two players and prompts the users to enter rock, paper or scissors. Your program does not have to produce any color. The color is there just to show you what your program should be inputting and outputting. The writing in blue represents output and writing in red represents input. Here are some sample runs:
Answer:
In Python
print("Instruction: 1. Rock, 2. Paper or 3. Scissors: ")
p1 = int(input("Player 1: "))
p2 = int(input("Player 2: "))
if p1 == p2:
print("Tie")
else:
if p1 == 1: # Rock
if p2 == 2: #Paper
print("P2 wins! Paper covers Rock")
else: #Scissors
print("P1 wins! Rock smashes Scissors")
elif p1 == 2: #Paper
if p2 == 1: #Rock
print("P1 wins! Paper covers Rock")
else: #Scissors
print("P2 wins! Scissors cuts Paper")
elif p1 == 3: #Scissors
if p2 == 1: #Rock
print("P2 wins! Rock smashes Scissors")
else: #Paper
print("P1 wins! Scissors cuts Paper")
Explanation:
This prints the game instruction
print("Instruction: 1. Rock, 2. Paper or 3. Scissors: ")
The next two lines get input from the user
p1 = int(input("Player 1: "))
p2 = int(input("Player 2: "))
If both input are the same, then there is a tie
if p1 == p2:
print("Tie")
If otherwise
else:
The following is executed if P1 selects rock
if p1 == 1: # Rock
If P2 selects paper, then P2 wins
if p2 == 2: #Paper
print("P2 wins! Paper covers Rock")
If P2 selects scissors, then P1 wins
else: #Scissors
print("P1 wins! Rock smashes Scissors")
The following is executed if P1 selects paper
elif p1 == 2: #Paper
If P2 selects rock, then P1 wins
if p2 == 1: #Rock
print("P1 wins! Paper covers Rock")
If P2 selects scissors, then P2 wins
else: #Scissors
print("P2 wins! Scissors cuts Paper")
The following is executed if P1 selects scissors
elif p1 == 3: #Scissors
If P2 selects rock, then P2 wins
if p2 == 1: #Rock
print("P2 wins! Rock smashes Scissors")
If P2 selects paper, then P1 wins
else: #Paper
print("P1 wins! Scissors cuts Paper")
