Answer:

Here is the C++ program:

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

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

bool verifyLength(string password);  // to verify length of password

bool verifyUpper(string password);  //to verify if  password contains uppercase letters

bool verifyLower(string password);  //to verify if  password has lowercase letters

bool verifyDigit(string password);  // to verify if password contains digits

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

   string password = " ";  //to hold password string input by user

  while(true)     {  //loop that verifies the password. The loop keeps prompting user to enter a valid password telling what criteria is to be met to verify password.

       cout << "\nPlease enter your password: ";  // prompts user to enter a password

       getline(cin, password);  //reads and gets password from user

           if (verifyLength(password) == false)  // calls verifyLength to check length criteria for password. Checks if length of password is less than 6

             { cout << "The password should be at least six characters long.\n";}                                        

else if (verifyUpper(password) == false)   { // calls verifyUpper to check criteria for password letters to be in uppercase. Checks if password does not have an uppercase letter

   cout << "The password should contain at least one uppercase letter.\n";  }  

         else if (verifyLower(password) == false) {  // calls verifyLower to check criteria for password letters to be in lowercase.  Checks if password does not contain a lowercase letter

           cout << "The password should contain at least one lowercase letter.\n";   }

          else if (verifyDigit(password) == false)  {   // calls verifyDigit to check digit criteria for password. Checks if password does not contain a digit

           cout << "The password should have at least one digit.\n";    }  

        else {  //if password meets the criteria

          cout << "Password verified!\n";  

         break;   }     } }   //breaks the loop                

Explanation:

Here are the method that are called to verify the stated criteria:  

bool verifyLength(string password)  {  // this method takes input password as parameter to verify the length criteria and returns true of false accordingly

   bool length = false;   // the bool type variable length is initially set to false

   if(password.length() >= 6)  //if the length of the password that is obtained by using length() function is greater than or equals to 6 then it means it meets valid password length criteria

   length = true;   //set length to true when above if statement is true

   else  //if length of password is less than 6

   length = false;   //set length to false if length of password  is less than 6

   return length;  }   //return the state of length

bool verifyUpper(string password)  {  // this method takes input password as parameter to verify the uppercase criteria and returns true of false accordingly

   bool upper = false;   // the bool type variable upper is initially set to false

   for (int i = 0; i < password.length(); i++)     { //the loop iterates through the letter of password string until the length of the string is reached

       if (isupper(password[i]))         {  //it checks if any letter of the password is in uppercase using the isupper() method

           upper = true;       }        }   //set upper to true when above if condition is true

   return upper;  }  //returns the state of upper

bool verifyLower(string password)  { // this method takes input password as parameter to verify the lowercase criteria and returns true of false accordingly

   bool lower = false;  // the bool type variable lower is initially set to false

   for (int i = 0; i < password.length(); i++)     { //the loop iterates through the letter of password string until the length of the string is reached

       if (islower(password[i]))         {  //it checks if any letter of the password is in lowercase using the islower() method

           lower = true;         }     }   //set lower to true when above if condition is true

   return lower;  } //returns the state of lower accordingly

bool verifyDigit(string password)  {  // this method takes input password as parameter to verify the digit criteria and returns true of false accordingly

   bool digit = false;   // the bool type variable digit is initially set to false

   for (int i = 0; i < password.length(); i++)     {  //the loop iterates through each letter of password string until the length of the string is reached

       if (isdigit(password[i]))         {  //it checks if any letter of the password is a digit using the isdigit() method

           digit = true;         }     } //set digit to true when above if condition is true

    return digit;  }    //returns the state of digit accordingly

Answer:

input number

calculate modulus of the number and 5

compare outcome to 0

if 0 then output "divisible by 5"

else output "not divisible by 5"

Explanation:

The modulo operator is key here. It returns the remainder after integer division. So 8 mod 5 for example is 3, since 5x1+3 = 8. Only if the outcome is 0, you know the number you divided is a multiple of 5.

Given that,

Token is 64 bytes long

The average number of stations that the token must pass = 20

We need to calculate the transmission delay for token

Using formula of transmission delay

[tex]Transmission\ delay=\dfrac{token\ size}{minimum\ size}[/tex]

Put the value into the formula

[tex]Transmission\ delay=\dfrac{64\ bytes}{10\ Mbps}[/tex]

[tex]Transmission\ delay=\dfrac{64\times8}{10\times10^6}[/tex]

[tex]Transmission\ delay=0.0000512\ sec[/tex]

[tex]Transmission\ delay=5.12\times10^{-5}\ sec[/tex]

We need to calculate the average wait to receive token on an idle network with 40 stations

Using formula of average wait

[tex]\text{average wait to receive token}=\text{average number of stations that the token must pass}\times transmission\ delay[/tex]

Put the value into the formula

[tex]\text{average wait to receive token}=20\times5.12\times10^{-5}[/tex]

[tex]\text{average wait to receive token}= 0.001024\ sec[/tex]

[tex]\text{average wait to receive token}= 1.024\ ms[/tex]

Hence, The average wait to receive token on an idle network with 40 stations is 1.024 ms.

Answer:

Infrastructure.

Explanation:

In Computer science, Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives. It offers individuals and businesses a fast, effective and efficient way of providing services.

Simply stated, Cloud computing are services or programs located on the Internet, they are usually remote resources making use of cloud storage.

When first defining the cloud, National Institute of Standards and Technology (NIST) gave three (3) service models, which can be viewed as nested service alternatives;

1. Software as a Service (SaaS).

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS).

According to NIST, the five (5) characteristics of a cloud computing service are;

1. On-demand self-service .

2. Broad network access .

3. Resource pooling .

4. Rapid elasticity .

5. Measured service.

Additionally, the cloud service can either be deployed as private, public, hybrid or community service.

}

We can overload this method by passing double values as arguments

public double sumValues(double num1, double num2){

       return num1 + num2;

}

Answer:

a) Linear probing is one of the hashing technique in which we insert values into the hash table indexes based on hash value.

Hash value of key can be calculated as :

H(key) = key % size ;

Here H(key) is the index where the value of key is stored in hash table.

----------

Given,

Keys to be inserted are : 5 , 205, 406,5205, 8205 ,307

and size of the array : 100.

First key to be inserted is : 5

So, H(5) = 5%100 = 5,

So, key 5 is inserted at 5th index of hash table.

-----

Next key to inserted is : 205

So, H(205) = 205%100 = 5 (here collision happens)

Recompute hash value as follows:

H(key) =(key+i) % size here i= 1,2,3...

So, H(205) =( 205+1)%100 = 206%100 = 6

So, key 205 is inserted in the 6th index of the hash table.

----------

Next Key to be inserted : 406

H(406) = 406%100 = 6(collision occurs)

H(406) =(406+1) %100 = 407%100 = 7

So, the value 406 is inserted in 7the index of the hash table.

-----------------

Next key : 5205

H(5205) = 5205%100 = 5(collision)

So, H(5205) = (5205+1)%100 = 6( again collision)

So, H(5205) = 5205+2)%100 = 7(again collision)

So, H(5205) = (5205+3)%100 = 8 ( no collision)

So, value 5205 is inserted at 8th index of the hash table.

-------------

Similarly 8205 is inserted at 9th index of the hash table because , we have collisions from 5th to 8th indexes.

-------------

Next key value is : 307

H(307) = 307%100 = 7(collision)

So, (307+3)%100 = 310%100 = 10(no collision)  

So, 307 is inserted at 10th index of the hash table.

So, hash table will look like this:

Key       index

5         5

205         6

406         7

5205 8

8205 9

307         10

b) Quadratic probing:

Quadratic probing is also similar to linear probing but the difference is in collision resolution. In linear probing in case of collision we use : H(key) = (key+i)%size but here we use H(key) =( key+i^2)%size.

Applying Quadratic probing on above keys:.

First key to be inserted : 5.

5 will go to index 5 of the hash table.

-------

Next key = 205 .

H(205) = 205%100 = 5(collision)

So. H(key)= (205+1^2)%100 = 6(no collision)

So, 205 is inserted into 6th index of the hash table.

--------

Next key to be inserted 406:

So, 406 %100 = 6 (collision)

(406+1^2)%100 = 7(no collision)

So, 406 is moved to 7th index of the hash table.

----------

Next key is : 5205

So, 5205%100 = 5 (collision)

So, (5205+1^2)%100 = 6 ( again collision)

So, (5205+2^2)%100 = 9 ( no collision)

So, 5205 inserted into 9th index of hash table.

-----------

Next key is 8205:

Here collision happens at 5the , 6the , 9th indexes,

So H(8205) = (8205+4^2)%100 = 8221%100 = 21

So, value 8205 is inserted in 21st index of hash table.

--------

Next value is 307.

Here there is collision at 7the index.

So, H(307) = (307+1^2)%100 = 308%100= 8.

So, 307 is inserted at 8the index of the hash table.

Key           Index

5                  5

205                  6

406                  7

5205                9

8205               21

307                   8

Phishing

Explanation:

Phishing is one of the most common social engineering attacks in which the attacker disguises to be a trustworthy personnel in order to lure the victim or target into disclosing sensitive information such as passwords, credit card details and so on.

Phishing could be carried out via emails, telephones, or even text messages.

In this case, the attacker pretends to be an IT tech in order to get your computer configuration details which he can then use to carry out some other fraudulent acts.

Another example is in the case of someone receiving an email from their bank requesting that they need to update their records and need the person's password or credit card PIN.

If someone posing as an IT tech requests information about your computer configuration, this kind of attack is: social engineering.

Social engineering can be defined as an art of manipulating people, especially the vulnerable to divulge confidential information or perform actions that compromises their security.

Basically, social engineering is a manipulative strategy (technique) which typically involves the use of deceptive and malicious tactics on vulnerable (unsuspecting) victims, so as to gain an unauthorized access to their confidential or private information, especially for fraud-related purposes.

In Cybersecurity, some examples of social engineering attacks include:
