A. None of the above
B. reduce risk of systems failures due to overloading
C. improve data quality and reduce redundancies, reduce increased and staggering storage management costs,
D. Both A and B
Answer:
C. improve data quality and reduce redundancies, reduce increased and staggering storage management costs
Explanation:
Excess data retention can lead to retention of redundant and irrelevant data, which can reduce data handling and processing efficiency, while at the same time increasing the cost of data storage and management. This can be curbed be reducing data to the right size by using data governance techniques like data cleansing and de-duplication
Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 5 7 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
/* Your solution goes here */
return 0;
}
2). Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
seedVal = 4;
srand(seedVal);
/* Your solution goes here */
return 0;
}
Answer:
1. The solution to question 1 is as follows;
srand(seedVal);
cout<<rand()%10<<endl;
cout<<rand()%10<<endl;
2. The solution to question 2 is as follows
cout<<100+rand()%50 <<endl;
cout<<100+rand()%50 <<endl;
Explanation:
The general syntax to generate random number between interval is
Random Number = Lower Limit + rand() % (Upper Limit - Lower Limit + 1)
In 1;
The solution starts by calling srand(seedVal);
The next two statements is explained as follows
To print two random integers between intervals of 0 and 9 using rand()"
Here, the lower limit = 0
the upper limit = 9
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 0 + rand() % (9 - 0 + 1)
Random Number = 0 + rand() % (10)
Random Number = rand() % (10)
So, the instruction to generate the two random variables is rand() % (10)
2.
Similar to 1 above
To print two random integers between intervals of 100 and 149 using rand()"
Here, the lower limit = 100
upper limit = 149
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 100 + rand() % (149 - 100 + 1)
Random Number = 100 + rand() % (50)
So, the instruction to generate the two random variables is 100 + rand() % (50)
write the following function so that it returns the same result, but does
not increment the variable ptr. Your new program must not use anysquare brackets, but must use an integer variable to visit each double in the array. You may eliminate any unneeded variable.
double computeAverage(const double* scores, int nScores)
{
const double* ptr = scores;
double tot = 0;
while (ptr != scores + nScores)
{
tot += *ptr; } ptr++;
}
return tot/nScores;
b. Rewrite the following function so that it does not use any square brackets (not even in the parameter declarations) but does use the integervariable k. Do not use any of the functions such as strlen, strcpy, etc.
// This function searches through str for the character chr.
// If the chr is found, it returns a pointer into str where
// the character was first found, otherwise nullptr (not found).
const char* findTheChar(const char str[], char chr)
{
for(intk=0;str[k]!=0;k++)
if (str[k] == chr)
}
return &str[k];
return nullptr;
}
c. Now rewrite the function shown in part b so that it uses neither square brackets nor any integer variables. Your new function must not use any local variables other than the parameters.
Answer:
Explanation:
a.
// Rewriting the given function without using any square brackets
double computeAverage(const double* scores, int nScores)
{
const double* ptr = scores;
double tot = 0;
int i;//declaring integer variable
for(i=0;i<nScores;i++)
{
//using an integer variable i to visit each double in the array
tot += *(ptr+i);
}
return tot/nScores;
}
b.
// Rewriting the given function without using any square brackets
const char* findTheChar(const char* str, char chr)
{
for(int k=0;(*(str+k))!='\0';k++)
{
if ((*(str+k)) == chr)
return (str+k);
}
return nullptr;
}
c.
//Now rewriting the function shown in part b so that it uses neither square brackets nor any integer variables
const char* findTheChar(const char* str, char chr)
{
while((*str)!='\0')
{
if ((*str) == chr)
return (str);
str++;
}
return nullptr;

The IBM 370 mainframe computer was introduced in 1970. The 370 Model 145 could hold up to 524,288 bytes of data (512 Kbytes). It cost $1,783,000.00 to buy (or $37,330/month to rent). A notebook computer today holds 16 Gbytes of memory and costs $2,500 to buy. If you assume that 100% of the price is just the memory, for both computers:
• how much did 1 Kbyte of memory in the IBM computer cost?
• how much does 1 Kbyte of memory in the laptop cost?
• how many times cheaper is the memory in the laptop than memory in the mainframe?
• what factor is today’s computer cheaper than the IBM 370?
Answer:
a) $3482.4 per Kbyte
b) $0.000149 per Kbyte
c) The laptop is 23369991 times cheaper than the mainframe computer
d) Today's computer is 23369991 times cheaper than IBM 370
Explanation:
a) The 370 Model 145 could hold up to 524,288 bytes of data
one Kb = 1024 bytes, therefore 524,288 bytes = 524288/1024 Kbytes= 512 Kbytes. It cost $1,783,000.00 to buy (or $37,330/month to rent).
Since 100% of the price is just the memory
Cost per 1 Kb = cost of computer / memory
Cost per 1 Kb = $1,783,000 / 512 Kb = $3482.4 per Kbyte
b) A notebook computer today holds 16 Gbytes of memory
one Kb = 1024 bytes, 1024 Kb = 1 Mbyte, 1024 Mbytes = 1 Gbyte.
Therefore 16 Gbytes = (16 * 1024 * 1024) Kbytes = 16777216 Kbytes. It cost $2500 to buy
Since 100% of the price is just the memory
Cost per 1 Kb = cost of computer / memory
Cost per 1 Kb = $2500 /16777216 Kb = $0.000149 per Kbyte
c) Cost per 1 Kb for mainframe/ Cost per 1 Kb for laptop = $3482.4 per Kbyte / $0.000149 per Kbyte = 23369991
The laptop is 23369991 times cheaper than the mainframe computer
d) Today's computer is 23369991 times cheaper than IBM 370
Suppose that class OrderList has a private attribute double cost[100] which hold the cost of all ordered items, and a private attributes int num_of_items which hold the number of items ordered. For example, if num_of_items is 5, then cost[0], cost[1], ..., cost[4] hold the cost of these 5 items. Implement the member function named total_cost which returns the total cost of this OrderList.
Answer:
OrderList.java
public class OrderList { private double cost[]; private int num_of_items; public OrderList(){ cost = new double[100]; } public double total_cost(){ double total = 0; for(int i=0; i < num_of_items; i++){ total += cost[i]; } return total; } }Main.java
public class Main { public static void main(String[] args) { OrderList sample = new OrderList(); double totalCost = sample.total_cost(); } }Explanation:
Firstly, define a class OrderList with two private attributes, cost and num_of_items (Line 1-3). In the constructor, initialize the cost attribute with a double type array with size 100. Next, create another method total_cost() to calculate the total cost of items (Line 9-15). To implement the total_cost member function, create an OrderList instance and use that instance to call the total_cost() and assign it to totalCost variable.

}
}
int sum = 0;
//Calculate total

The common field cricket chirps in direct proportion to the current temperature. Adding 40 to the number of times a cricket chirps in a minute, then dividing by 4, gives us the temperature (in Fahrenheit degrees). Write a program that accepts as input the number of cricket chirps in fifteen seconds, then outputs the current temperature
Answer:
This program is written in Java programming language;
First, you should understand that:
The formula given in the question implies that the current temperature can only be calculated using measurement of time in minutes;
Given that the number of chirps is directly proportional to the temperature.
If the cricket made n chirps in 15 seconds, it will make n * (60/15) chirps in 1 minutes;
n * (60/15) = n * 4
Base on this analysis, the program is as follows
import java.util.*;
public class cricket
{
public static void main(String []args)
{
//Declare number of chips in 1 minutes
int num;
Scanner input = new Scanner(System.in);
//Prompt user for input
System.out.print("Number of chirps (in 15 seconds): ");
num = input.nextInt();
//Calculate temperature (multiply temperature by 4 to get number of chirps in minutes
double temp = (num * 4+ 40)/4;
//Print temperature
System.out.print("Current Temperature = "+temp+" F");
}
}

Write a calling statement for the following code segment in Java: public static int sum(int num1, int num2, String name) { int result = num1 + num2; System.out.println("Hi " + name + ", the two numbers you gave me are: " + num1 + " " + num2); return result; } Function Integer sum(Integer num1, Integer num2, String name) Integer result = num1 + num2 Display "Hi " + name + ", the two numbers you gave me are: ", num1, " ", num2 Return result End Function Write a calling statement to the function in Java or Pseudocode. You may use any value of appropriate data samples to demonstrate your understanding.
Answer:
Following are the calling of the given question
public static void main(String[] args) // main function
{
int store; // variable declaration
store = sum(32,15,"san"); // Calling of sum()
System.out.println(" TheValue returned by sum() : "+store); // display
}
Explanation:
Following are the description of the above statement
Here is the name of function is sum() In the sum() function definition there are 3 parameter in there signature i.e two "int" type and 1 is "string" type .In the main function we declared the variable store i,e is used for storing the result of sum() it means it storing the result of value that is returning from the definition of sum() function .After that calling the function by there name and passing three parameter under it sum(32,15,"san"); and store in the "store" variable.Finally print the value by using system.out.println ().#Write a function called "scramble" that accepts a string #as an argument and returns a new string. The new string #should start with the last half of the original string #and end with the first half. # #If the length of the string is odd, split the string #at the floor of the length / 2 (in other words, the second #half is the longer half). # #For example: # scramble("abcd") -> "cdab" # screamble("abcde") -> "cdeab" # scramble("railroad")) -> "roadrail" # scramble("fireworks")) -> "worksfire"
Answer:
def scramble(s):
if len(s) % 2 == 1:
index = int(len(s)//2)
else:
index = int(len(s)/2)
return s[index:] + s[:index]
Explanation:
Create a function called scramble that takes one parameter, s
Check the length of the s using len function. If the length is odd, set the index as the floor of the length/2. Otherwise, set the index as length/2. Use index value to slice the s as two halves
Return the second half of the s and the second half of the s using slice notation (s[index:] represents the characters from half of the s to the end, s[:index] represents the characters from begining to the half of the s)
. The total processing speed of microprocessors (based on clock rate and number of circuits) is doubling roughly every year. Today, a symmetric session key needs to be 100 bits long to be considered strong. How long will a symmetric session key have to be in 30 years to be considered strong?
Answer:
130 bits
Explanation:
If the length of a key = N bits
Total number of key combinations = [tex]\frac{2^{N} }{2}[/tex]
For a key length of 100, the total number of key combinations will be [tex]\frac{2^{100} }{2} = 2^{99}[/tex] combinations. This is a whole lot and it almost seems impossible to be hacked.
The addition of one bit to the length of the symmetric key in 1 year is sufficient to make the key strong, because even at double its speed, the processor can still not crack the number of combinations that will be formed.
Therefore, if a bit is added to the key length per year, after 30 years, the length of the symmetric session key will be 130 bits.

C++ Problem: In the bin packing problem, items of different weights (or sizes) must be packed into a finite number of bins each with the capacity C in a way that minimizes the number of bins used. The decision version of the bin packing problem (deciding if objects will fit into <= k bins) is NPcomplete. There is no known polynomial time algorithm to solve the optimization version of the bin packing problem. In this homework you will be examining three greedy approximation algorithms to solve the bin packing problem.
- First-Fit: Put each item as you come to it into the first (earliest opened) bin into which it fits. If there is no available bin then open a new bin.
- First-Fit-Decreasing: First sort the items in decreasing order by size, then use First-Fit on the resulting list.
- Best Fit: Place the items in the order in which they arrive. Place the next item into the bin which will leave the least room left over after the item is placed in the bin. If it does not fit in any bin, start a new bin.
Implement the algorithms in C++. Your program named bins.cpp should read in a text file named bin.txt with multiple test cases as explained below and output to the terminal the number of bins each algorithm calculated for each test case. Example bin.txt: The first line is the number of test cases, followed by the capacity of bins for that test case, the number of items and then the weight of each item. You can assume that the weight of an item does not exceed the capacity of a bin for that problem.

The main() module in the starter code below takes integar inputs separated by commas from the user and stores them in a list. Then, it allows the user to manipulate the list using 3 functions:
mutate_list() takes 3 parameters -- a list, index number, and a value -- and inserts the value in the position specified by the index number in the list.
remove_index() takes 2 parameters -- a list and an index number -- and remove the element at the position number indicated by index. It also prints the total number of elements in the list before and after removing the character in this fashion:"Total elements in list = 11
Total elements in list = 10"
reverse_list() takes 1 parameter -- a list -- and returns the list reversed.
Examples:
Example 1:
Enter values in list separated by commas: 1,2,4,63,6,4,22,53,76
[1, 2, 4, 63, 6, 4, 22, 53, 76]

Part 1: For this assignment, call it assign0 Implement the following library and driver program under assign0: Your library will be consisting of myio.h and myio.c. The function prototypes as well as more explanations are listed in myio.h. Please download it and accordingly implement the exported functions in myio.c. Basically, you are asked to develop a simple I/O library which exports a few functions to simplify the reading of an integer, a double, and more importantly a string (whole line). In contrast to standard I/O functions that can read strings (e.g., scanf with "%s", fgets) into a given static size buffer, your function should read the given input line of characters terminated by a newline character into a dynamically allocated and resized buffer based on the length of the given input line. Also your functions should check for possible errors (e.g., not an integer, not a double, illigal input, no memory etc.) and appropriately handle them. Then write a driver program driver.c that can simply use the functions from myio library. Specifically, your driver program should get four command-line arguments: x y z output_filename. It then prompts/reads x many integers, y many doubles, and z many lines, and prints them into a file called output_filename.txt. Possible errors should be printed on stderr.

Francis has designed a picture book appropriate for third graders. He wants teachers across the world to freely download use, and distribute his work, but he would still like to retain his copyright on the content. What type of license should he u for his book?
Answer:
The correct answer will be "Project Gutenberg".
Explanation:
Project Gutenberg continues to obtain lots of requests for authorization for using printed books, pictures, as well as derivatives from eBooks. Perhaps some applications should not be produced, because authorization would be included in the objects provided (as well as for professional usages).You can copy, hand it over, or m actually-use it underneath the provisions including its license that was included in the ebook.So that the above is the right answer.
Write a program that keeps track of where cars are located in a parking garage to estimate the time to retrieve a car when the garage is full. This program will demonstrate the following:_________.
How to create a list for use as a stack,
How to enter and change data in a stack.
Answer: Provided in the explanation section
Explanation:
Code to use;
# Define the main() function.
def main():
# Declare the required variables.
stack_cars = []
move_time = 1
retrieve_time = 2
# Start the loop to display the menu.
while True:
# Display the choices to the user.
print("\n\t\t\t Car Stack Menu")
print("\n1. Add a car")
print("2. Retrieve a car")
print("3. Show the car stack")
print("4. Exit")
# Prompt the user to enter the input.
choice = input("\nEnter your choice: ")
# Append the car in the stack if the choice is 1.
if choice == '1':
car = input("Enter the car name to add: ")
stack_cars.append(car)
# Remove the car from the stack if the choice is 2.
elif choice == '2':
car = input("Enter the car name to retrieve: ")
# Display the error message if the car is not present.
if car not in stack_cars:
print(car + " is not present in the stack.")
# Otherwise, compute the time to retrieve a car.
else:
# Declare a temp stack to move the cars.
temp = []
x = stack_cars.pop()
count = 0
# Start the loop to pop the cars from the stack
# until the car to be retrieved is found.
while x != car:
count += 1
# Store the car in the temp stack.
temp.append(x)
x = stack_cars.pop()
# Start the loop to move the cars back in the
# original stack.
while len(temp) != 0:
stack_cars.append(temp.pop())
# Compute and display the total time.
total_time = move_time * count + retrieve_time
print("Total time to retrieve", car, "=", total_time)
# Display the stack if the choice is 3.
elif choice == '3':
print("Car stack =", stack_cars)
# Return from the funtion if the choice is 4.
elif choice == '4':
print("Exiting from the program...")
return
# Display the message for invalid input.
else:
print("Error: Invalid choice!")
# Call the main() function.

Doctoral candidates should provide an authentic personal statement to each of the five following questions/prompts reflecting on their own personal interest. In the event that any outside resources are used, resources should be cited in APA format. Submissions should be a maximum of 500 words or 125 words per question/prompt. It is best to response to each prompt/question individually for clarity of the reviewer. Writing sample should be submitted in Microsoft Word format and include candidate’s name.
PhD IT
1. Tell us about yourself and your personal journey that has lead you to University of the Cumberlands.
2. What are your research interests in the area of information technology? How did you become interested in this area of research?
3. What is your current job/career and how will this program impact your career growth?
4. What unique qualities do you think you have that will help you in being successful in this program?
5. How can obtaining a doctorate impact your contribution to the practices of information technology? Where do you see yourself after obtaining a doctorate from UC?
Explanation:
1. I grew up in a small community and my family owned a small business which involved manual labor. Although, having little income, my Dad sought to give us the best education he could afford from his little savings. With the small family savings I went to college where I studied Information Technology, after graduating I worked for a startup firm for two years before I decided to proceed with post graduate studies and I attained my Masters in UA. I met a friend who recommended I study in University of Cumberlands, I hesitated initially but was convinced after I researched the institution.
2. I'm particularly interested in the applications of information technology in labor intensive businesses and work because of my family background.
3. I have my own startup firm that designs work communication software for companies, however I intend to broaden my knowledge through this program into Information Technology based systems using machine learning algorithm.
4. I am committed to work and study, as some have called me a curious mind because of my passion towards learning.
5. I view obtaining a doctorate as not just a personal achievement but of lasting benefits to society as I use knowledge derived to improve the work experience of society.
I am confident that after my program I would be one the renowned contributors to the applications of information technology in labor intensive businesses.
