Exercise : Randomizer In this exercise, we are going to create a static class Randomizer that will allow users to get random integer values from the method nextInt() and nextInt(int min, int max). Remember that we can get random integers using the formula int randInteger = (int)(Math.random() * (range + 1) + startingNum). nextInt() should return a random value from 1 - 10, and nextInt(int min, int max) should return a random value from min to max. For instance, if min is 3 and max is 12, then the range of numbers should be from 3 - 12, including 3 and 12.
Answer:
Here the code is by using java.
Explanation:
//Randomizer.java
public class Randomizer {
public static int nextInt() {
//get random number from 1-10
int randInteger = (int) (Math.random() * (11) + 1);
//if number is greater than 10 or less than 1
while (randInteger > 10 || randInteger < 1) {
randInteger = (int) (Math.random() * (11) + 1);
}
return randInteger;
}
public static int nextInt(int min, int max) {
//formula to get random number from min-max
int randInteger = (int) (Math.random() * (max + 1) + min);
while (randInteger > max || randInteger < min) {
randInteger = (int) (Math.random() * (max + 1) + min);
}
return randInteger;
}
}
//RandomizerTester.java
public class RandomizerTester {
public static void main(String[] args) {
System.out.println("Results of Randommizer.nextInt()");
for (int i = 0; i < 10; i++) {
System.out.println(Randomizer.nextInt());
}
int min = 5;
int max = 10;
System.out.println("\n Results of Randomizer.nextInt(5,10)");
for (int i = 0; i < 10; i++) {
System.out.println(Randomizer.nextInt(min, max));
}
}
}
OUTPUT:

Joe has just started the Security Module. He wants to get through it as quickly as possible and take the Quiz. As he clicks through the unit, he sees a bunch of text with some activities sprinkled throughout, and is trying to decide how to proceed.
Required:
Which strategies would likely be most effective and efficient for Joe?
Answer:
Joe should read the explanatory text and complete the learning activities.
Explanation:
Given
See attachment for options
Required
Best strategy to get through the module
First off, rushing through the activities and taking guess for each question (as suggested by (a)) will not help him;
He may complete the activities but sure, he won't learn from the module.
Also, reading through the units without completing the activities is not an appropriate method because Joe will not be able to test his knowledge at the end of the module.
The best strategy to employ is to read through the units and complete the activities, afterwards (option (b)).

At the application layer, entitlement rules can define the protocols allowed to be used.c. At the system layer, identity, and attributes used as part of the entitlement rules can stop or restrict access, or may direct access to a particular interface, for example, a web interface rather than a full-GUI interface.d. At the process layer, entitlement can be used to define the processes or functions run within an application. Entitlement can also specify that enhanced functions require additional verification (which can prompt the user or run in the background).
Answer:
Option D
Explanation:
An Entitlement is an option to utilize, get to or devour an application or asset, commonly for a charge. For instance, a client may buy an Entitlement to utilize an application in ceaselessness (a "unending" permit), or they may buy a period restricted option to utilize an application, (for example, a one-year membership permit).

Write a complete program that asks the user to input the height and radius of a cone (both of type double) and calls two individual functions to calculate the total area of the cone and the volume of the cone. The main function then prints these values with appropriate messages.
Answer:
The program in C++ is as follows:
#include <iostream>
#include <math.h>
using namespace std;
double area(double r, double h){
double A = 3.14 * r * (r + sqrt(h*h + r*r));
return A;}
double volume(double r, double h){
double V = (1.0/3) * 3.14 * r*r * h;
return V;}
int main(){
double radius, height;
cout<<"Radius: "; cin>>radius;
cout<<"Height: "; cin>>height;
cout<<"Area: "<<area(radius,height)<<endl;
cout<<"Volume: "<<volume(radius,height);
return 0;
}
Explanation:
This declares the area function
double area(double r, double h){
Calculate area
double A = 3.14 * r * (r + sqrt(h*h + r*r));
Return the calculated area
return A;}
This declares the volume method
double volume(double r, double h){
Calculate volume
double V = (1.0/3) * 3.14 * r*r * h;
Return the calculated volume
return V;}
The main begins here
int main(){
Declare radius and height
double radius, height;
Get input for radius
cout<<"Radius: "; cin>>radius;
Get input for height
cout<<"Height: "; cin>>height;
Call the area function and print the returned value for area
cout<<"Area: "<<area(radius,height)<<endl;
Call the volume function and print the returned value for volume
cout<<"Volume: "<<volume(radius,height);
return 0;
}

c. It is an input device that enables users to convert hard copies to digital images or text.
d. It is a device that enables users to input photographs as digital images.
Answer:
c. It is an input device that enables users to convert hard copies to digital images or text.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
A scanner can be defined as an input device designed for transferring informations and images from hardcopy (physical) documents to digital computer files. Thus, it's simply an electronic input device that is used to digitally scan or copy data (informations) from a hardcopy document such as photographs, paper files, printed texts etc and then converted to a digital computer file in formats such as png, or jpeg. The scanner is a device which avail users the ability and opportunity to view, edit and transfer hardcopy document on a computer system in soft-copy.
Majority of the scanners used around the world are flatbed scanners and as such have a flat glass surface for scanning documents.
Basically, all scanners are to be used with a device driver software pre-installed on the computer before the configuration of the scanner.
Other types of scanners are drum scanners, contact image sensor (CIS) scanner, CCD scanner, planetary scanner, 3D scanner, Roller scanner etc.

Write a program whose input is two integers, and whose output is the first integer and subsequent increments of 5 as long as the value is less than or equal to the second integer. Ex: If the input is: "-15" 10 the output is: "-15" "-10" "-5" 0 5 10 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first.
Answer:
The program in Python is as follows:
num1 = int(input())
num2 = int(input())
if num2 < num1:
print("Second integer can't be less than the first.")
else:
for i in range(num1,num2+1,5):
print(i,end=" ")
Explanation:
This gets the first integer from the user
num1 = int(input())
This gets the second integer from the user
num2 = int(input())
If the second is less than the first, the following prompt is printed
if num2 < num1:
print("Second integer can't be less than the first.")
If otherwise, the number between the intervals is printed with an increment of 5
else:
for i in range(num1,num2+1,5):
print(i,end=" ")

Write an application that inputs a five digit integer (The number must be entered only as ONE input) and separates the number into its individual digits using MOD, and prints the digits separated from one another. Your code will do INPUT VALIDATION and warn the user to enter the correct number of digits and let the user run your code as many times as they want (LOOP). Submit two different versions
Answer:
The programs are written in python:
Version 1:
n = int(input("Numbers: "))
for i in range(n):
num = int(input("Input integer: "))
mylist = []
while num>0:
mylist.append(num%10)
num= int(num/10)
mylist.reverse()
for i in mylist:
print(i,end=" ")
print()
Version 2:
num = int(input("Input integer: "))
while num > 0:
mylist = []
while num>0:
mylist.append(num%10)
num= int(num/10)
mylist.reverse()
for i in mylist:
print(i,end=" ")
print()
num = int(input("Input integer: "))
Explanation:
Version 1:
This gets the number of inputs from the user, n
n = int(input("Numbers: "))
This iterates through n
for i in range(n):
For each iteration, this gets the integer input from the user, num
num = int(input("Input integer: "))
This initializes a list
mylist = []
This loop is repeated until num is 0
while num>0:
This gets the individual digit and appends it to a list
mylist.append(num%10)
This gets the other numbers
num= int(num/10)
This reverses the list
mylist.reverse()
This prints the individual digits from the list
for i in mylist:
print(i,end=" ")
Print a new line for the next integer input
print()
Version 2:
The difference in both versions are the following lines
This gets the integer input from the user
num = int(input("Input integer: "))
This loop enables the user to input as many numbers as possible. But once the user inputs 0, the program will stop
while num > 0:
Unlike version 1 where the number of inputs in known at the initial stage of the program

Among the following protocols, terminology or considerations, indicate those that are associated with routing within a single network (typically owned and operated by one organization
a. BGP
b. OSPF
c. inter-AS routing
d. intra-AS routing
e. inter-domain routing
f. intra-domain routing
g. Driven more by performance than by routing policy
h. Driven more by routing policy than end-end routing performance
The protocol is indeed a set of rules and principles for data transmission and the further discussion can be defined as follows:
OSPF (Open Shortest Path First) is indeed a routing system that aids in data routing by calculating the best shortest path inside a single network.Intra-AS (Autonomous System) networking establishes links and routes packets within automated driving. No one in it has access to it.Intra-domain routing employs IGP (Interior Gateway Protocol), which directs packets inside one specific domain or between domains.A few more organizations will not seriously evaluate routing policies. It is also influenced by performance.Therefore, the answer is Option "b,d,f, and g".
