Answer:

#include <iostream>

using namespace std;

int main()

{

   const int YEAR = 2050;

   int currentYear = 2020;

   int currentAge = 38;

   cout<<"You will be " << currentAge + (YEAR - currentYear) << " years old in " << YEAR;

   return 0;

}

Explanation:

Initialize the YEAR as a constant and set it to 2050

AJAX

The word that is not an HTTP verb is AJAX.

But PUT, GET, and DELETE are HTTP verbs.

A HTTP verb is a word or method (it can also be a noun) for retrieving information (documents) in a web-based environment.  There are other HTTP verbs used for various purposes.  The most common include PUT, GET, DELETE, and POST.

HTTP is a computer-based abbreviation that means Hypertext Transfer Protocol.  It is the protocol for transferring data over the web using a client's home computer, laptop, or mobile device.

AJAX, which means Asynchronous Javascript and XML, is mainly used as a technique for creating fast and dynamic web pages using small amounts of data.

Answer:

A bandwidth is the maximum rate of transfer of data across a given path

Latency refers to the delay of data to travel or move between a source and destination

An example of a high bandwidth and high latency network is the Satellite Internet connectivity.

An example of a low bandwidth and latency network is the telephone system connection.

Explanation:

Solution

Bandwidth: Bandwidth determines how fast data can be transferred for example, how many bits/sec it can transport.

Latency: It refers to the delay or how long it takes for data to travel between it's source and destination.

An example of a high bandwidth and high latency network is the Satellite internet connection.

Satellite internet connection: This is responsible for the connectivity of several systems, it has a high bandwidth, since satellite are in space, due to distance it has a high latency.

So, satellite internet connection is compensated with high latency and high bandwidth.

An example of a low bandwidth and low latency network is the Telephony network.

Telephone/telephony internet connection: This connection does not have much data for transfer. it has low size audio files of which a low bandwidth range. also for both end or end users to understand and talk to each other, it has low latency.

An example of a network that exhibits high bandwidth but also high latency is Satellite internet connection.

An example of one that has both low bandwidth and low latency is telephony internet connection.

Based on the provided information, we can say that Satellite internet connection posses high bandwidth but also high latency because, the fastness of data transfer is based on the bandwidth and how the data to travel between it's source and destination is based on its latency.

We can conclude that telephony internet connection has low bandwidth and low latency because of low data transfer is required.

Answer:

The programming language is not stated;

For this, I'll answer your question using c++ programming language

The program does not make use of comments (See explanation for further details)

From the sample run, the input numbers are integer; So, this program assumes that all input will be integer...

Program starts here

#include<iostream>

using namespace std;

int main()

{

cout<<"Enter six numbers: ";

int Arr[6];

for(int i = 0;i<6;i++)

{

 cin>>Arr[i];

}

bool flag = true;

for(int i = 0;i<6;i++)  

{

for(int j = i;j<6;j++)

{

 if(Arr[i]>Arr[j])

 {

  flag = false;

 }

}

}

string isAscending;

if(flag)

{

isAscending = "True";

}

else

{

isAscending = "False";

}

cout<<isAscending;

return 0;

}

Explanation:

cout<<"Enter six numbers: ";  -> This line prompts the user for input

int Arr[6]; -> The input is stored in an array; This line declares the array

The following for loop iteration is used to iterate through the array

for(int i = 0;i<6;i++)

{

 cin>>Arr[i];  -> This line accepts user input

}

bool flag = true;  -> A boolean variable is initialized to true

The following nested loop checks if numbers are in ascending order

for(int i = 0;i<6;i++)  

{

for(int j = i;j<6;j++)

{

 if(Arr[i]>Arr[j])  -> This particular if statement checks if a number is greater than the next number

 {

  flag = false;  -> If yes, the boolean variable is changed to false

 }

}

}  - > The nested loop ends here

string isAscending  = "True";  -> Here, isAscending is declared as string

if(flag)  If boolean variable flag is true; i

{

isAscending = "True";  "True" is assigned to isAscending

}

else  -> Otherwise; if boolean variable flag is no longer true; i.e if it's false

{

isAscending = "False"; -> "False" is assigned to isAscending

}

cout<<isAscending;  -> The corresponding value of isAscending is printed

The complete program that reads 6 numbers and assigns True to variable isAscending if the numbers are in ascending order is as follows;

number = 0

list1 = []

while number < 6:

    x = input("enter six number: ")

    number += 1

    list1.append(x)

if sorted(list1)==list1:

    print("True")

else:

    print("False")

Answer:

The overview of the given question is described in the explanation segment below.

Explanation:

The number of casualties has occurred in recent years. The following are indeed the assaults:

Arbitrary Remote Code execution attacks:

It's also a very hazardous assault. Unsanitary working on implementing that used operating system including user actions could enable an attacker to execute arbitrary functions mostly on system files.

Sites become targeted with such a DOS assault that will cause them inaccessible whether they close the account to an offender who threatens them.

Prevention: We could protect this by preventing the call from additional assessment by the user. We will disinfect input validation if we transfer values to devise calls. The input data is permitted to transfer on requests, it should have been strictly regulated although restricted to a predetermined system of principles.

Injection attack:

The object of the Injection Attack seems to be to delete vital information from the server. Throughout the list, we have such a user, a code, as well as a lot of several other essential stuff. Assailants are taking vital data and doing the wrong stuff. This can have an impact on the web site or software application interface the SQL.

Prevention: Parameterized functions require developers must specify all of the SQL code, and afterward move the question in-parameter, allowing the server to distinguish between some of the code as well as the information. By decreasing the privilege allocated to each database. White list data validation has been used to prevent abnormal information.

Zero-day attack:

It corresponds to something like a vulnerability flaw undisclosed to the user. The security vulnerability becomes infected with malware. The attackers have access to inappropriate details.

Prevention: The organizations are releasing the patch fixes the found holes. The updated plugin is also a preventive tool.

Buffer overflow attack:

This is indeed a major security threat to the accuracy of the data. This overflow happens since more information becomes set to either a specified size than even the buffer could accommodate. Adjoining program memory is compromised. During that time, the attacker was indeed running obfuscated code. Two key forms of such attack are provided below:

Prevention: Standard library features, including such strcpy, should indeed be avoided. Standard testing should be performed to identify as well as resolve overflow.

Answer:

Explanation:

Firstly, declare the necessary variables and initialize them with zero (Line 4-8). Next create a Scanner object to get user input for score (Line 10). Create a while loop by using the counter as limit (Line 12). In the while loop, prompt user to input a number between 1 - 100 (Line 13-14). Create another while loop to check the input must be between 1 - 100 or it will print invalid message and ask for user input again (Line 15-19).

Next, create an if-else statement to check if the current score is equal or above 60. If so print pass if not print fail (Line 21-27). At the same time increment the fail and pass counter.

Create another two if statement to get the current highest and lowest score and assign them to highest and lowest variables, respectively (Line 29-35).

Increment the counter by one before proceeding to the next loop to repeat the same process (Line 37).

At last, print the required output after finishing the while loop (Line 40-43).

import math

h = 19

total = 0

for i in range(1, h):

   if math.sqrt(i) - int(math.sqrt(i)) == 0:

       total += i

print(total)

Explanation:

*The code is in Python.

Initialize the h and total

Create a for loop that iterates from 1 to h. Inside the loop, check if the difference between the square root of a number and the integer part of the square root of that number is equal to 0 (This means the number is a perfect square. For example, if the number is 3, the square root is 1.73 and the integer part of this is 1, the difference is 0.73, not 0. However, if the number is 4, the square root is 2.0 and the integer part is 2, the difference is 0), add that number to the total

When the loop is done, print the total.

The question seem incomplete as the list is not given and the programming language is not stated;

To answer this question, I'll answer this question using Python programming language and the program will allow user input.

Input will stop until user enters 0

The program is as follows

newlist = []

print("Input into the list; Press 0 to stop")

userinput = int(input("User Input:"))

while not userinput == 0:

     newlist.append(userinput)

     userinput = int(input("User Input:"))

is_ascending = "True"

i = 1

while i < len(newlist):  

     if(newlist[i] < newlist[i - 1]):  

           is_ascending = "False"

     i += 1

print(newlist)

print(is_ascending)

Explanation:

This line declares an empty list

newlist = []

This line prompts gives instruction to user on how to stop input

print("Input into the list; Press 0 to stop")

This line prompts user for input

userinput = int(input("User Input:"))

This next three lines takes input from the user until the user enters 0

while not userinput == 0:

     newlist.append(userinput)

     userinput = int(input("User Input:"))

The next line initialized "True" to variable is_ascending

is_ascending = "True"

The next 5 line iterates from the index element of the list till the last to check if the list is sorted

i = 1

while i < len(newlist):  

     if(newlist[i] < newlist[i - 1]):  

           is_ascending = "False"

     i += 1

The next line prints the list

print(newlist)

The next line prints the value of is_ascending

print(is_ascending)

Answer & Explanation:

To print 10 on a line and each number separated by space; you make the following modifications.

print(str(i)+" ",end=' ')

str(i)-> represents the actual number to be printed

" "-> puts a space after the number is printed

end = ' ' -> allows printing to continue on the same line

if(count == 10):

     print(' ')

The above line checks if count variable is 10;

If yes, a blank is printed which allows printing to start on a new line;

The modified code is as follows (Also, see attachment for proper indentation)

count = 0

for i in range(100,201):

     if(i%6 == 0 and i%5!=0) or (i%5 ==0 and i%6!=0):

The data can be safeguarded using key escrow procedure.

Explanation:

Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.

       elif inp>=80 and inp<90:

           print("B")

       elif inp>=70 and inp<80:

           print("C")

       elif inp>=60 and inp<70:

           print("D")

       else:

   else:

       print("Letter Grade: F")

   print(" ")

for i in range(2):

   name = input("Student Name: ")

   result = calc_average(name)

   determine_grade(result)

Explanation:

def calc_average(name):  -> Declares the function calc_average(name); It accepts local variable name from the main function

   score = []

-> Initialize an empty list to hold test scores

   sum = 0

-> Initialize sum of scores to 0

   for j in range(8):

-> Iterate from test score 1 to 8

       inp = int(input("Test Score"+str(j+1)+": "))

-> This line accepts test score from the user

       score.append(inp)

-> The user input is then saved in a lisy

       sum = sum + inp

-> Add test scores

The following lines determine the letter grade of each test score      

if inp>=90 and inp<=100:

           print("A")

---

      else:

           print("F")

   avg = sum/8  -> Calculate average of the test score

The next two lines prints the name and average test score of the student

   print("Result Details of "+name)

   print("Average Score: "+str(avg))

   return avg

-> This line returns average to the main method

The following is the determine_grade method; it takes it parameter from the main method and it determines the letter grade depending on the calculated average

def determine_grade(result):

   if float(result) >= 90.0 and float(result) <= 100.0:

       print("Letter Grade: A")

   elif float(result) >= 80.0 and float(result) <90.0:

       print("Letter Grade: B")

   elif float(result) >= 70.0 and float(result) < 80.0:

       print("Letter Grade: C")

   elif float(result) >= 60.0 and float(result) < 70.0:

       print("Letter Grade: D")

   else:

       print("Letter Grade: F")

   print(" ")

for i in range(2):

-> This is the main method

   name = input("Student Name: ")  -> A local variable stores name of the student

   result = calc_average(name)  -> store average of scores in variable results

   determine_grade(result)-> Call the determine_grade function

In this exercise we have to use the computer language knowledge in python to write the code as:

the code is in the attached image.

In a more easy way we have that the code will be:

def calc_average(name):

  score = []

  sum = 0

  for j in range(8):

      inp = int(input("Test Score"+str(j+1)+": "))

      score.append(inp)

      sum = sum + inp

      if inp>=90 and inp<=100:

          print("A")

      elif inp>=80 and inp<90:

          print("B")

Answer:

Here is the C++ program:

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

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

int counter(string userString, char character) { //function counter

   int count = 0;   // counts the no of times a character appears in the string

   for (int i=0;i<userString.length();i++)  

// loop to move through the string to find the occurrence of the character

       if (userString[i] == character) //if characters is found in the string

           count++;   //counts the occurrence of the character in the string

   return count; }   //returns the no of times character occurs in the string

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

   string s; // stores the string entered by the user

   cout<<"Enter a string: "; //prompts user to enter the string

   cin>>s; //reads the string from user

   char ch; //stores the character entered by the user

   cout<<"Enter a character: "; //prompts user to enter a character

   cin>>ch; //reads the character from user

   cout << counter(s, ch) << endl; }  

//calls counter function to find the number of times a character occurs in the //string

Explanation:

The counter function works as following:

It has a count variable which stores the number of occurrences of a character in the userString.

It uses a for loop which loops through the entire string.

It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.

If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.

If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.

After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.

The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

Answer:

The programming language is not stated; I'll answer this question using C++ programming language;

Another thing to note is that; the sample run is quite different from the illustration in the question; So, I'll assume the program to print "Youth is a wonderful thing. Enjoy.", if and only if age is less than or equal to 21

The program is as follows

#include<iostream>

using namespace std;

int main()  {

int age;

int i =1;

start:

cout<<"Sample run: "<<i<<endl;

cout<<"You entered: ";

cin>>age;

if(age<=21)  {

 cout<<"Youth is a wonderful thing. Enjoy."<<endl; }

cout<<"Age is a state of mind"<<endl;

i++;

cout<<"Run another? (Y/N): ";

char resp;

cin>>resp;

if(resp=='Y')

{

 goto start;

}

return 0;

}

Explanation:

Line 4 of the program declares age as integer

Line 5 declares and initializes a counter variable, i to 1

Line 6 is used as a label to start another sample run

Line 7 prints the Sample run in the following format;

        Sample run 1, during the first iteration

        Sample run 2, during the second iteration; and so on...

Line 8 prompts the user to supply details for age

Line 9 stores user input in variable age

Line 10 checks if age is less than or equal to 21

If true, the program outputs Youth is a wonderful thing. Enjoy., then it continues execution on line 23

Otherwise, it jumps directly to line 23 and outputs Age is a state of mind

The counter is increased by 1 on line 24

The program asks if the user wants to take another sample run on line 25

The response is saved in a char variable on line 27

If the user response is Y, the program goes to the label on line 6 to begin another iteration

Otherwise, the program is terminated.

Answer:

c. role- or function-specific.

Explanation:

The Security Configuration Wizard was  firstly used by Microsoft in its development of the Windows Server 2003 Service Pack 1. It provides guidance to network security administrators, secure domain controllers, firewall rules and reduce the attack surface on production servers.

Security Configuration Wizard saves any changes that are made as a role- or function-specific security policy which can be used as a baseline and applied to other servers in the network.

After checking the Group policy by an administrator, any changes made as a role- or function-specific security policy by the Security Configuration Wizard (SCW) is used as a baseline and can be applied either immediately or sometimes in the future to other servers in the network after testing it in a well secured environment.

Basically, the Microsoft Security Configuration Wizard (SCW) typically help administrators in running the following;

1. Role-Based Service Configuration.

2. Registry settings.

3. Network and Firewall Security settings.

4. Auditing Policy settings.

Answer:

This is the complete question:

for i ∈ {1,2,3,4,5,6} do  beep  

for j ∈ {1,2,3,4} do  beep  

for k ∈ {1,2,3} do

    for l ∈ {1,2,3,4,5} do beep  

for m ∈ {1,2,3,4} do  beep

Explanation:

I will explain the algorithm line by line.

for i ∈ {1,2,3,4,5,6} do  beep  

This statement has a for loop and i variable that can take the values from 1 to 6. As there are 6 possible values for i so the beep statement gets executed 6 times in this for loop.

for j ∈ {1,2,3,4} do  beep  

This statement has a for loop and j variable that can take the values from 1 to 4. As there are 4 possible values for j so the beep statement gets executed 4 times in this for loop.

for k ∈ {1,2,3} do

    for l ∈ {1,2,3,4,5} do beep  

There are two statements here. The above statement has a for loop and k variable that can take the values from 1 to 3. As there are 3 possible values for k so the beep statement gets executed 3 times in this for loop. The below statement has a for loop and l variable that can take the values from 1 to 5. As there are 5 possible values for l so the beep statement gets executed 5 times in this for loop. However these statement work like an inner and outer loop where the outer loop is k and inner one is l which means 1 gets executed for each combination of values of k and l. As there are three values for k and 5 possible values for l so the combinations of values of k and l is 15 because 3 * 5 = 15. Hence the beep statement gets executed 15 times.

for m ∈ {1,2,3,4} do  beep

This statement has a for loop and m variable that can take the values from 1 to 4. As there are 4 possible values for m so the beep statement gets executed 4 times in this for loop.

Now lets take the sum of all the above computed beeps.

for i = 6 beeps

for j = 4 beeps

for k and l possible combinations = 15 beeps

for m = 4 beeps

total beeps = 6 + 4 + 15 + 4 = 29 beeps

Answer:

Hello your question lacks the required options

A) Business impact analysis plan

B) Business continuity plan

C) Disaster recovery plan

D) Recovery point plan

answer : Disaster recovery plan ( c )

Explanation:

The Disaster recovery  plan is a comprehensive creation of a system/set procedures of recovery of the IT infrastructure from potential threats of a company. especially when the interruption is caused by a disaster, accident or an emergency.

The shutting down of the sever due to overheating and not able to restart for Business is an interruption in a critical business process and the plan to direct the recovery for this single server should be the " Disaster recovery plan"

Answer:

During a traceroute, the router decreases the Time To Live values of the packet sent from the traceroute by one during routing, discards the packets whose Time To Live values have reached zero, returning the ICMP error message ICMP time exceeded.

Explanation:

Traceroute performs a route tracing function in a network. It is a network diagnostic commands that shows the path followed, and measures the transit delays of packets across an Internet Protocol (IP) network, from the source to the destination, and also reports the IP address of all the routers it pinged along its path. During this process, the traceroute sends packets with Time To Live values that increases steadily from packet to packet; the process is started with Time To Live value of one. At the routers, the Time To Live values of the packets is gradually decreased by one during routing, and the packets whose Time To Live values have reached zero are discarded, returning the ICMP error message ICMP Time Exceeded
