Answer:
Because reusing the old passwords possess security threats.
Explanation:
A password can be defined as a string of characters or words or phrases that are used to authenticate the identity of the user. It is also known as passcode and should be kept confidential. A password is used to access constricted systems, applications, etc.
A password or passcode is usually composed of alphabets, numbers, symbols, characters, alphanumeric, or a combination of these.
In the given case, Judy was not able to change her passcode to the previous one because reusing old passwords is prohibited in any sites or systems. A system denies the user to reuse the old passwords for various reasons but most importantly due to security reasons. Though it is said that old passwords can be used after 100 times but seldom someone changes a password that much. All systems care for the security of their users thus they deny reusing old passcodes.

Write a program using integers userNum and x as input, and output userNum divided by x four times. Ex: If the input is 2000 2, the output is: 1000 500 250 125 Note: In Coral, integer division discards fractions. Ex: 6 / 4 is 1 (the 0.5 is discarded).
Answer:
import java.util.Scanner;
public class Division {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter an integer");
int userNum = in.nextInt();
System.out.println("Enter the divisor");
int x = in.nextInt();
int first = userNum/x;
int second = first/x;
int third = second/x;
int fourth = third/x;
System.out.println(first+" "+second+" "+third+" "+fourth);
}
}

In Java programming langauge use the scanner class to receive the values from the user (userNum and x)Carryout integer division of userNum/x to obtain the first numberRepeat the sam step to obtain the second, third and fourth numberOutput the numbers to the userThe student's question was about writing a program to divide an integer by another integer four times using integer division. The provided code is written in Python, demonstrating the process of capturing input and repeatedly dividing and outputting the result.
To solve the student's question, we need to create a simple program that takes two integers as input, userNum and x, and outputs the result of userNum divided by x four times. Each division operation will use integer division, which discards any fractions that might result from the division.
Example Code in Python:
Assuming they are learning programming using Python, which is common in high school:
userNum, x = map(int, input("Enter two integers separated by a space: ").split())
for _ in range(4):
userNum //= x
print(userNum, end=' ')
This code snippet reads two integers from the user, then performs integer division of userNum by x in a loop that runs four times. After each division, the program prints the current value of userNum, followed by a space.
The function below tries to create a list of integers by reading them from a file. The file is expected to have a single integer per line and the code works correctly in that case. If any of the lines don't contain just an integer, than this code fails. Fix this code so that it ignores any lines that don't contain integers instead of raising an exception. Do this with try/except blocks. Your code should still return the list of integers from the lines that contain integers.

Design and document an IP addressing scheme to meet ElectroMyCycle’s needs. Specify which IP address blocks will be assigned to different modules of your network design. Document whether you will use public or private addressing for each module. Document whether you will use manual or dynamic addressing for each module. Specify where (if anywhere) route summarization will occur.
Answer:
Given that: Design scenario - page 197 has a continuation of the chapter 1 design scenario for ElectroMyCycle
Explanation:
See attached image
Final answer:
An IP addressing scheme for ElectroMyCycle involves using private addresses for internal networks with a combination of manual and dynamic addressing, public addresses for the DMZ, and route summarization at the router connecting to the ISP.
Explanation:
To design an IP addressing scheme for ElectroMyCycle, one must consider both the size of the network and the security requirements. The following is a tentative plan:
Headquarters: Use private addressing (e.g., 192.168.1.0/24) because these IP addresses do not need to be routable to the Internet. Dynamic addressing through DHCP can be applied here for ease of management.
Production Facility: Use a separate block of private addresses (e.g., 192.168.2.0/24) and manual addressing for fixed assets like servers, while dynamic addressing can be used for employee devices.
Sales Offices: Smaller subnets of private addresses (e.g., 192.168.3.0/28) with dynamic addressing would be appropriate.
DMZ (Demilitarized Zone): This area, which contains public-facing servers, should use public IP addresses for accessibility from the Internet. Manual addressing is recommended for these critical assets.
Route summarization can occur at the router connecting the headquarters to the ISP, summarizing the multiple private subnets into a single entry in the routing table to simplify the routing process and reduce overhead.

Write a script that will generate random integers in the range from
0 to 50, and print them, until one is finally generated that is greater
than 25. The script should print how many attempts it took.
Answer:
Explanation:
Let's do this in Python, we shall use the package random to generate a random double between 0 and 1. Then we multiply it with 50 and covert to integer to get a random integer between 0 and 50. Place a While function with condition to stop when it's greater than 25
from random import random
attempts = 1
random_int = int(random()*50)
print(random_int)
print("This is attempt " + attempts)
while random_int <= 25:
attempts += 1
random_int = int(random()*50)
print(random_int)
print("This is attempt " + attempts)
The length of a hailstone sequence is the number of terms it contains. For example, the hailstone sequence in example 1 (5, 16, 8, 4, 2, 1) has a length of 6 and the hailstone sequence in example 2 (8, 4, 2, 1) has a length of 4. Write the method hailstoneLength(int n), which returns the length of the hailstone sequence that starts with n. /** Returns the length of a hailstone sequence that starts with n, * as described in part (a). * Precondition: n > 0 */ public static int hailstoneLength(int n)
Answer:
Following are the program to this question:
#include <iostream> //defining header file
using namespace std;
int hailstoneLength(int n) //defining method hailstoneLength
{
int t=1; //defining integer variable assign
while(n!=1) //define a loop that checks value is not equal to 1
{
if(n%2==0) // check even number condition
{
n=n/2; // divide the value by 2 and store its remainder value in n
t++; //increment value of t by 1.
}
else
{
n=n*3+1; //calculate and hold value in n
t++; //increment value of t variable by 1
}
}
return t; //return value
}
int main() //defining main method
{
int n; //defining integer variable
cout<<"Enter any number: "; //print message
cin>> n; //input value
cout<<hailstoneLength(n); //call method and print its value
return 0;
}
Output:
Enter any number: 3
8
Explanation:
Program description can be given as follows:
In the given C++ language program an integer method "hailstoneLength", is declared, that accepts an integer variable "n" in its parameter. Inside the method, an integer variable t is declared, that assign a value that is 1, in the next line, a while loop is declared, that uses if block to check even condition if number is even it divide by 2 and increment t variable value by 1. If the number is odd it will multiply the value by 3 and add 1 and increment t by 1 then it will go to if block to check value again. when value of n is not equal to 1 it will return t variable value. In the main method, an integer variable "n" is used that call the method and print its return value.Which of the following is NOT correct concerning database design?
1. Identify all fields needed to produce the required information
2. Organize each piece of data into its largest useful part
3. Group related fields into tables
4. Determine each table’s primary key
Final answer:
The incorrect statement regarding database design is the directive to organize each piece of data into its largest useful part as data should actually be in the smallest useful part to avoid redundancy and maintain normalization.
Explanation:
The statement that is NOT correct concerning database design is Organize each piece of data into its largest useful part. Instead, data should be organized into the smallest useful part, to ensure normalization and avoid redundancy. The design process includes determining the purpose of the database, identifying fields, grouping related fields into tables, and establishing primary and foreign keys to ensure relationships between tables.
The purpose of the primary key is to ensure that each record in a table is unique, which is crucial to maintain data integrity. A good design also considers the use of foreign keys to link tables together and maintain referential integrity. The goal is to prevent redundant data, which avoids wasting space and reduces the occurrence of data entry errors.

Design a class called NumDays. The class’s purpose is to store a value that represents a number of work hours and convert it to a number of days. For example, 8 hours would be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hours would be converted to 2.25 days. The class should have a constructor that accepts a number of hours, as well as member functions for storing and retrieving the hours and days. The class should also have the following overloaded operators: • (+) Addition operator. When two NumDays objects are added together, the overloaded + operator should return the sum of the two objects’ hours members. • (-) Subtraction operator. When one NumDays object is subtracted from another, the overloaded − operator should return the difference of the two objects’ hours members. Part 2: Design a class named TimeOff.

Cache size = 128 KB = 128×2¹⁰ bytes = 2¹⁷ bytes
(a). we are asked to cal for fully associative mapping with line size of 4 words.
fully associative mapping with line size of 4 words = 4 × 8 = 32 bytesoffset = log₂³² = 5 bittag = 32 - (5+0) = 27 bit index bit = 0(b). Direct mapping with the line size of 8 words:
here the line size = 8×8 = 64 bytes no of lines = 2¹⁷/2⁶ = 2¹¹ lines offset = log ₂(2⁶) = 6 bitindex = log ₂(2¹¹) = 11 bittag = 32 - (5 +11) = 15 bit(c). 2-way set associated mapping with the line size of 1 word:
no of lines = 2¹⁷/2³ = 2¹⁴ linesoffset = log₂(2³) = 3 bitno of sets = 2¹⁴/2 = 2¹³ sets index = log₂(2¹³) = 13 bittag = 32 - (3+13) = 16 bit(d). 8-way set associated mapping with the line size of 2 words:
8-way set associated mapping with the line size of 2 = 2*8 = 16 bytes
no of lines = 2¹⁷/2⁴ = 2¹³ linesno of sets = 2¹³/2³ = 2¹⁰ sets offset = log₂¹⁶ = 4 bitindex = log ₂(2¹⁰) = 10 bittag = 32 - (4+10) = 18 bitcheers i hope this helps!!!!
In Section 8.5.4, we described a situation in which we prevent deadlock by ensuring that all locks are acquired in a certain order. However, we also point out that deadlock is possible in this situation if two threads simultaneously invoke the transaction () function. Fix the transaction () function to prevent deadlocks.
Answer:
See Explaination
Explanation:
Separating this critical section into two sections:
void transaction(Account from, Account to, double amount)
{
Semaphore lock1, lock2;
lock1 = getLock(from);
lock2 = getLock(to);
wait(lock1);
withdraw(from, amount);
signal(lock1);
wait(lock2);
deposit(to, amount);
signal(lock2);
}
will be the best solution in the real world, because separating this critical section doesn't lead to any unwanted state between them (that is, there will never be a situation, where there is more money withdrawn, than it is possible).
The simple solution to leave the critical section in one piece, is to ensure that lock order is the same in all transactions. In this case you can sort the locks and choose the smaller one for locking first.
In the lab, you discovered that the server you scanned (10.20.1.2) was vulnerable to the WannaCry ransomeware attack. What ports are affected and what are the recommended remediations? Why is it important to perform penetration testing on networks and individual servers?
Answer:
Check the explanation
Explanation:
If Zenmap SYN scan did not work in your lab, then that means the application could not locate the network you were attempting to scan, i.e. 10.20.1.0/24. Recall that in Section 2.
Part 2. You added a Route for 10.20.1.0 to be routed via the 172.30.0.1 gateway. That route you added to communicate with the 10.20.1.0 network is a temporary route and will be replaced each time.
This program has one small difference that will make it run a little differently. Again though, remember:
All your code outside the draw loop is run first, one time
All your code inside the draw loop is run over and over forever
What will this program do? Write your prediction below.
Answer:
Answer:
Add the following code after the line 3 that is:
numItems = numItems - 1;
Explanation:
In the following question, some information in the question is missing that is code block.
0 var numItems = promptNum("How many items?");
1 var total = 0;
2 while (numItems > 0){
3 total = total + promptNum("Enter next item price");
4 }
5 console.log("The total is" + total);
In the following scenario, Tiffany is developing a program to help with the handling of bake sales and she not write that part which is essential.
There would become an incorrect condition that requires any increment/decrement operations stating that perhaps the condition variable will be incorrect. Because there has to be the variable "numItems" operation because it engages in the while loop condition.

Explanation:
Susan was recently fired from her executive IT position. You have concerns that she has enough knowledge and expertise to sabotage company documents—and you need to delete her access. However, upon beginning, you find information that should be retained in her user directory for future company needs. Consider the process you would take to ensure that Susan no longer has access and that data is retained. In situations like this, do you think the benefits outweigh the risks enough to retain user information? Why or why not?
Answer:
The answer is No, the gains or benefit do not exceed the risk because, even if the data of the user seem very vital, the damage it would have on the long will affect the organisation in a negative way.
Explanation:
From the example given, stating that in situations like this, do you think the benefits outweigh the risks enough to retain user information? Why or why not
I would say that NO, the benefits do not outweigh the risk that will be enough to keep the user information because, just as the user data is important, but the damage it would yield or have could affect the organization on the long run.

Implement the function create_prefix_lists(list) that will return a sequence of lists, each containing a prefix of list. All the lists should be collected as one big list. For example, for [2, 4, 6, 8, 10] the function should return [[], [2], [2, 4], [2, 4, 6], [2, 4, 6, 8], [2, 4, 6, 8, 10]]. Note: recursion can not be used for this solution, if you are familiar with the concept.

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.). c
Final answer:
A program can calculate the estimated monthly mortgage using the formula (currentPrice * 0.051) / 12 and determine the percentage change in house prices to analyze market trends.
Explanation:
Sites like Zillow provide summaries of house prices to give accurate estimates of home values. When writing a program to output a summary of the current price, last month's price, and the estimated monthly mortgage, one can use the formula provided in the question to calculate the mortgage. The estimated monthly mortgage is computed using the formula (currentPrice * 0.051) / 12. It's also important to note that the percentage change in house prices is an important metric when analyzing real estate data, which can be computed as [(current price - last month's price) / last month's price] * 100. This will help in understanding the real estate market trends.
