Which statement is written correctly?

Answer:

b) all the threads should be duplicated

Explanation:

The fork provides a process to start a new one, and the new process is not the same program. The exec system call com in play. Exec replaces the currently running process with information. The process is launching a new program firstly fork and create a new process. Exec load into memory. Fork copies of all attribute the new process except for memory. A clone system call implements the kernel fork. Forking provides the existing process. And the thread should be duplicated.

Answer:

Here is the JAVA program to calculate volume of cuboid:

import java.util.Scanner; // Scanner class is used to take input from user

public class CuboidVol { // class to calculate volume of cuboid

public static void main(String[] args) { // start of main() function body

Scanner input= new Scanner(System.in); //create Scanner class object

// prompts user to enter length of cuboid

System.out.println("Enter the cuboid length:");

double length=input.nextDouble(); //reads the input length value from user

// prompts user to enter width of cuboid

System.out.println("Enter the cuboid width:");

double width=input.nextDouble(); //reads the input width from user

// prompts user to enter height of cuboid

System.out.println("Enter the cuboid height:");

double height=input.nextDouble(); //reads the input height from user

/* the following formula is to calculate volume of a cuboid by multiplying its length width and height and a double type variable cuboidVolume is defined to store the value of the resultant volume to it */

double  cuboidVolume= length*width*height; //calculates cuboid volume

//displays volume of cuboid and result is displayed up to 2 decimal places

System.out.printf("Volume of the cuboid (length " + length + "/ height " + height + "/ width" +width +" is: " + "%.2f",cuboidVolume);   } }

Explanation:

The formula for the volume of a cuboid is as following:

Volume = Length × Width ×  Height

So in order to calculate the volume of cuboid three variable are required for length, width and height and one more variable cuboidVolume to hold the resultant volume of the cuboid.

The program is well explained in the comments added to each statement of the program. The program prompts the user to enter the value of height width and length of cuboid and the nextDouble() method is used to take the double type input values of height length and width. Then the program declares a double type variable cuboidVolume to hold the result of the volume of cuboid. Then the last printf statement is used to display the volume of cuboid in the format format "Volume of the cuboid (length  / height  / width ) is" and the result is displayed up to 2 decimal places.

The screenshot of the program along with its output is attached.

Answer: symmetric encryption

Explanation:

The Secure Sockets Layer (SSL) protocol is required by the Web servers and the web browsers in order to protect the data of the users during transfer through the creation of an encrypted channel that is unique for private communications that occur over the Internet.

The Secure Sockets Layer relies on the encryption in order to secure the link that exists between the client and the server which is the website.

This implies that the encryption and also the decryption of the data will be done using a cryptographic key that is shared. The cryptographic key will be generated and shared on accordance with transport layer security handshake.

d. all are correct statements

Explanation:

CARRIER ETHERNET can be defined as the Ethernet which is a telecommunications network providers that provides and enables all Ethernet services to their customers and as well to help them utilize the Ethernet technology in their networks which is why the word “Carrier” in Carrier Ethernet networks is tend to refers to a large communications services providers that has a very wide reach through all their global networks. Example of the carriers are:

They help to provide audio, video, as well as data services to residential and to all business as well as enterprise customers.

CARRIER ETHERNET also make use of high-bandwidth Ethernet technology for easy Internet access and as well as for communication among the end users.

Therefore all the statement about CARRIER ETHERNET NETWORK are correct

a. Metro Ethernet Forum (MEF) is a type of ethernet which created a Carrier Ethernet framework in order to ensure the interoperability of service provider that the Carrier Ethernet is offerings.

b. The MEF also help to certifies CE network providers, as well as the manufacturers and network professionals in order to ensure interoperability as well as a great service competencies.

c. MEF certified services also include E-Line, E-LAN, E-Tree, E-Access, and E-Transit

Hence, MEF is an important part of Carrier Ethernet because they act as the defining body for them, reason been that they are as well telecommunications service providers, cable MSOs, as well as network equipment and software manufacturers among others.

Answer:

The three primitive data types in JavaScript are:

1. Numbers

2. Strings of text(known as "strings")

3. Boolean Truth Values (known as "booleans")

Answer:

import random

guess = int(input("Make a guess: "))

total = count = 0

while total < 100:

   roll = random.randint(1, 6)

   total += roll

   count += 1

if guess == count:

   print("Your guess is correct")

elif guess > count:

   print("Your guess is high")

else:

   print("Your guess is low")

Explanation:

*The code is in Python.

Import the random module to simulate the dice roll

Ask the user to make a guess

Initialize the total and count as 0

Create a while loop that iterates while the total is smaller than 100. Inside the loop, use random to get a random number between 1 and 6 and set it to the roll. Add the roll to the total. Increment the count by 1.

When the loop is done, check the guess and count. If they are equal, that means the guess is correct. If the guess is greater than the count, that means it is high. If the previous cases are not true, then the guess is low.

Answer:

The answer is "AP//"

Explanation:

In the given question choices were missing so, the correct choice can be defined as follows:

The 3-bit color description of 'CYAN' is 011 if we convert it into 3- byte binary representation, we get,  the 3- byte binary representation that is equal to 011 =  00000000 11111111 11111111  and to split the 3-byte description into 6-bit subset to transform into Base64. so, we get:  000000 001111 111111 111111

if we have the Base64 alphabet table to convert the 6-bit representation towards its comparable letter or character by the 6-bit subgroup, that can be defined as follows:

link encryption

Explanation:

In e-mail, SSL/TLS provides link encryption.

The SSL is an acronym for Secured Socket Layer and it is one of the secured way of authenticating and encrypting data between a computer and the mail server.

In the case of a TLS, it is an acronym for Transport Layer Security and it basically is used for providing authentication and encryption of data between two communicating systems on a network.

This ultimately implies that, SSL/TLS are standard network protocols that provides data integrity and privacy to users when communicating over the internet or networking devices as they're made to encrypt user credentials and data from unauthorized access. The SSL/TLS are an application layer protocol used for the encryption of mails sent over the internet, in order to protect user information such as username and password.

Answer:

Buffer-overflow.

Explanation:

If a program writes more information into the computer's memory than the memory was designed to hold, it is a buffer-overflow attack.

A buffer in computer technology can be defined as a temporary area set aside for data storage. Buffers reside in the random access memory (RAM). In the event that, a system process or program places more data (much more than what was originally or initially intended to be allocated for data storage) in a buffer, the extra data overflows. Consequently, this would result in having some of the data to flow into other buffers and thus, causing the data to be overwritten or corruption of the data being held in that buffer.

For instance, we can liken a buffer-overflow to pouring water (data) into a container (program memory), once it is filled the water begins to overflow as the container has reached its maximum amount.

In a buffer-overflow attack, the hacker or attacker use the extra data to influence certain unauthorized actions such as getting privy informations, damaging a file, compromising a data, corrupting a software program etc.

The common types of buffer-overflow attacks are;

1. Heap-overflow attack.

2. Stack-overflow attack.

3. Unicode-overflow attack.

4. Integer-overflow attack.

In conclusion, the buffer-overflow attack could be prevented through the randomization of the address space.

Create a program that compares the unit prices for two sizes of laundry detergent sold at a grocery store. Console Price Comparison Price of 64 oz size: 5.99 Price of 32 oz size: 3.50 Price per oz (64 oz): 0.09 Price per oz (32 oz): 0.11

Using Python

Answer:

This program does not make use of comments (See explanation section)

price64 = float(input("Price of 64 oz size: "))

price32 = float(input("Price of 32 oz size: "))

unit64 = price64/64

unit32 = price32/32

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

if unit64>unit32:

     print("Unit price of 64 oz is greater" )

else:

     print("Unit price of 32 oz is greater" )

Explanation:

This line prompts the user for the price of 64 oz size

price64 = float(input("Price of 64 oz size: "))

This line prompts the user for the price of 32 oz size

price32 = float(input("Price of 32 oz size: "))

This line calculates the unit price of 64 oz size

unit64 = price64/64

This line calculates the unit price of 32 oz size

unit32 = price32/32

This next two lines print the unit prices of both sizes

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

The next line compares the unit prices of both sizes

if unit64>unit32:

This line is executed if the unit price of 64 oz is greater than 32 oz

     print("Unit price of 64 oz is greater" )

else:

This line is executed, if otherwise

     print("Unit price of 32 oz is greater" )

Answer:

According to the principles of design, Repetition refers to the recurrence of elements of the design

One of the advantages of this is that it affords uniformity. Another is that it keeps the user of such a system familiar or with the interface of the operating system.

One major drawback of this principle especially as used in the question is that it creates a familiar route for hackers.

Another drawback is that creates what is called "repetition blindness". This normally occurs with perceptual identification tasks.

The  phenomenon may be  due to a failure in sensory analysis to process the same shape, figures or objects.

Answer:

Here is the modified DemoSalesperson2

public class DemoSalesperson2{ // class DemoSalesperson2

public static void main(String[] args) { //start of main() function body

SalesPerson[] sp = new SalesPerson[10]; // creates an array of SalesPerson object named sp

int start_id =111; // assign 111 to starting id number

double start_sal=25000; //assign 25000 to starting salary means salary will start from amount 25000

 for (int i =0; i<sp.length; i++) { //loop iterates until the value of loop variable i remains less then length of the array object sp

  sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i)); /*at each iteration  ID number from 111 through 120 and a sales value that ranges from $25,000 to $70,000, increasing by $5,000 for each successive is displayed using object array sp[] which calls the SalesPerson constructor to access id and sales */

 System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  } } } /*uses object sp of class SalesPerson to access the methods getId which returns the id and getAnnualSales method which returns the annual sales, to display id and annual sales */

Explanation:

The question first requires a SalesPerson class with these requisites:

Class name: Salesperson.

Data fields for Salesperson: int ID number , double annual sales amount.

Methods: constructor SalesPerson() that requires values for both data fields, as well as get and set methods for each of the data fields.

So according to the complete question's requirement, I have implemented SalesPerson class:

public class SalesPerson {   // class name

//data members: integer type id variable and double type sales variable

   private int id;  

   private double sales;  

   public SalesPerson(int id_no, double annual_sales) {   //constructor that requires values for id and sales

       id = id_no;  

       sales = annual_sales;     }  

   public int getId() {   //accessor getId() method to get or access the value of id data field

       return id;     }  

   public void setId(int id_no) {   //mutator setId to set the value of id data field

       id = id_no;     }  

   public double getAnnualSales() {   //accessor getAnnualSales() method to get or access the value of sales data field

       return sales;     }  

   public void setAnnualSales(double annual_sales) { //mutator setAnnualSales to set the value of sales data field

       sales = annual_sales;     }  }

However you can use my DemoSalesperson2 application for your own SalesPerson class.

Now I will explain the working of for loop used in DemoSalesperson2

Iteration 1:

i=0

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 0 = 111

start_sal+5000*(i) = 25000 + 5000 (0) = 25000

The values 111 and 25000 are stored to sp[0] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

111   25000.0

Iteration 1:

The value of i is incremented to 1 so now i = 1

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 1 = 112

start_sal+5000*(i) = 25000 + 5000 (1) = 25000 + 5000 = 30000

The values 111 and 25000 are stored to sp[1] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

112   30000.0

The loop keeps iterating and the value of id is incremented by 1 and value of sales is increased by 5000 at every iteration.

This loop continues to execute until the value of i exceeds the length of sp array i.e. 10.

The values from iteration 1 to 8 following the above explanation are:

Iteration 1:

111    25000.0

Iteration 2:

112    30000.0

Iteration 3:

113    35000.0

Iteration 4:

114   40000.0  

Iteration 5:

115   45000.0  

Iteration 6:

116   50000.0                                                          

Iteration 7:

117   55000.0                                                                                                      

Iteration 8:                                                                                      

118   60000.0      

Iteration 9:                                                                                    

119   65000.0

Iteration 10:                                                                                    

120   70000.0

At iteration 11 the for loop body will not execute as value of i at 11th iteration is i = 10 and i<sp.length evaluates to false as i = sp.length because length of sp array is 10 and now the value of i is also 10. So the loop ends. Screenshot of the program and its output is attached.

Answer:

False

Explanation:

The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class  .The public member are accessible inside the class so they are accessible by using the dot operator .

Following are the example is given below in C++ Language

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {     return 3.14*r*r;  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 3.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Output:

compile time error is generated

The correct program to access the private member of class is given below

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {    

r1=r;

double t2=3.14*r2*r2;

return(t2); // return the value  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 1.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Therefore the given statement is False

Answer:

Threat assessment

Explanation:

A threat assessment deals with the potential for weaknesses within the existing infrastructure to be exploited.

Threat Assessment is further explained as the practice of determining or ascertaining the credibility and seriousness of a potential threat, and also the probability or chases of the threat will becoming a reality.

Threat assessment is separate to the more established procedure of violence-risk assessment, which seek to forcast an individual's general capacity and tendency to respond to situations violently. Instead, threat assessment aims to interrupt people on a route to commit "predatory or instrumental violence, the type of behavior connected with targeted attacks".

Answer:

Threat assessment

Explanation:

In an IT system, threat assessment is the analysis, evaluation and prevention of actions, events and operations that can greatly affect the system. It explores the potential for weaknesses within existing infrastructure to be exploited.

The threat assessment is a very important assessment that needs to be taken in virtually all domains. Here are a few reasons why it is important in an IT system;

i. Prevention of data loss

ii. Prevention of system or network of systems downtime

In carrying out threat assessment, one might need to do the following;

i. identification and prioritization of infrastructure including the software and hardware applications in the system.

ii. identification of potential threats such as system failure, natural disaster, unwanted access.

iii. identification of vulnerabilities in the system.

iv. analysing controls by determining who has access and who doesn't.

v. analysing the impact of a threat occurrence.

vi. documentation of analysis and evaluation results.

Answer:

Here is the sentinel-controlled while loop:

#include <iostream> //to use input output functions

using namespace std; // to identify objects like cin cout

int main(){ // start of main() function body

int test_score; // declare an integer variable for test scores

//prompts user to enter test scores and type-99 to stop entering scores

cout << "Enter the test scores (enter -99 to stop): ";

cin >> test_score; // reads test scores from user

while (test_score != -99){ // while loop keeps executing until user enters -99

cin >> test_score; } } // keeps taking and reading test scores from user

Explanation:

while loop in the above chunk of code keeps taking input scores from user until -99 is entered. Sentinel-controlled loops keep repeating until a sentinel value is entered. This sentinel value indicates the end of the data entry such as here the sentinel value is -99 which stops the while loop from iterating and taking the test score input from user.

The complete question is that the code should then report how many scores were  entered and the average of these scores. Do not count the end sentinel -99 as a score.

So the program that takes input scores and computes the number of scores entered and average of these scores is given below.

#include <iostream>  // to use input output functions

using namespace std;  // to identify objects like cin cout

int main(){  //start of main function body

double sum = 0.0;  // declares sum variable to hold the sum of test scores

int test_score,count =0;  

/* declares test_scores variable to hold the test scores entered by user and count variable to count how many test scores input by user */

cout << "Enter the test scores (or -99 to stop: ";

//prompts user to enter test scores and type-99 to stop entering scores

cin >> test_score;  // reads test scores from user

while (test_score != -99){  // while loop keeps executing until user enters -99

count++;  /* increments count variable each time a test cores is input by user to count the number of times user entered test scores */

sum = sum + test_score;  // adds the test scores

cin >> test_score;}  // reads test scores from user

if (count == 0)  // if user enters no test score displays the following message

cout << "No score entered by the user" << endl;

else  //if user enters test scores

//displays the numbers of times test scores are entered by user

cout<<"The number of test scores entered: "<<count;

/* displays average of test scores by dividing the sum of input test scores with the total number of input test scores */

cout << "\n The average of " << count << " test scores: " <<sum / count << endl;}

The program along with its output is attached.

Following are the code to this question:

public class Locker //defining a class Locker

{

public static void main(String[] ax)//defining main method  

{

boolean[] locker = new boolean[101]; //defining boolean array locker that's size is 100.

int j,s1,k1,x;

x=locker.length;

for (j=1;j<x; j++)//defining loop to assigns value false in locker array

{

locker[j] = false;// assign value false

}

for (j=1;j<x; j++)//defining loop loop to assign value true in array  

{

locker[j] = true;//assign value true

}

for(s1=2; s1<x; s1++)//defining loop to count locker from 2nd place

{

for(k1=s1; k1<x; k1=k1+s1)// defining inner loop to assign value  

{

if(locker[k1]==false) //defining if block for check false value  

{

   locker[k1] = true;// if condition is true it assign value true

}

else //defining else block

{

   locker[k1] = false;//assign value false in locker array

}

}

}

for(s1=1; s1<x; s1++)//defining loop to print locker value

{

if (locker[s1] == true) //defining if block that check Locker array value is equal to true

{

System.out.println("Locker " + s1 + " Open");//print Locker value with message  

}  

}

}

}

Output:

Locker 1 Open

Locker 4 Open

Locker 9 Open

Locker 16 Open

Locker 25 Open

Locker 36 Open

Locker 49 Open

Locker 64 Open

Locker 81 Open

Locker 100 Open

Explanation:

In the above code, a class "Locker" is declared, inside the class main method is declared, in which a boolean array "locker" is declared that's size is 100, in the next line fouth integer variable " j,s1,k1, and x" is declared, in which variable x is used to hold the boolean array length value, and other variable used in the loop.

Answer:

I am writing a C program:

#include <stdio.h> //to use input output functions

void printIt(double annual_in){ //function printIt

   if(annual_in >90000) //check if the income is greater than 90000

   printf("Congratulations. Doing great!"); //print this message if income value is greater than 90000

   else //if annual income is less than 90000

   printf("You WILL make $50,000, if you keep going"); } //print this message if income value is less than 90000

int main() //start of main() funciton body  

{   double income; //declares a double type variable income to hold annual income value

   printf("Enter annual income: "); //prompts user to enter annual income

   scanf("%lf",&income); //reads income value from user

   printIt(income); } // calls printIt method by passing input income to that function

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The flowchart is attached.

First flowchart flow1 has a separate main program flowchart which reads the income and calls printIt function. A second flowchart is of prinIt() method that checks the input income passed by main function and displays the corresponding messages and return.

The second flowchart flow2 is the simple flowchart that simply gives functional description of the C program as flowchart is not where giving function definitions is important. Instead of defining the function printIt separately for this C program, a high-level representation of functional aspects of this program is described in second flowchart while not getting into implementation details.

Answer:

a) Penetration test

Explanation:

A penetration test, often referred to as a pen test, is part of important process in the development of internet facing service. It is a process of determining if vulnerabilities are actually exploitable in a particular environment.

In other words, it is a process that involves a simulated cyber attack against computer system to check for exploitable vulnerabilities or attempts to actively exploit weaknesses in an environment.

Hence, when discussing the behavior of vulnerability assessments the choice that will exploit a weakness is PENETRATION TEST.

When discussing the behavior of vulnerability assessments, the choice which will exploit a weakness is: A) Penetration test.

Cyber security can be defined as a preventive practice to systematically protect computers, software applications (programs), networks, electronic devices, servers and user data from potential attack, damage, theft or an unauthorized access, especially through the use of technologies, frameworks, integrity principles, processes, penetration test and network engineers.

A vulnerability can be defined as a weakness in an automated internal control system and security procedures, which may be exploited by an attacker (hacker) to gain unauthorized access to the data stored on a computer system or disrupt the information system.

Basically, vulnerability assessments can be used in the following ways:

A penetration test is also referred to as pen test or ethical hacking and it can be defined as a cybersecurity technique that simulates a cyber attack against a user's computer system, so as to identify, test an check for exploitable vulnerabilities in a web software, network, etc.

This ultimately implies that, a penetration test avails an end user the ability to exploit a weakness and potential security threats during vulnerability assessments.
