Define the instance method inc_num_kids() for PersonInfo. inc_num_kids increments the member data num_kids. Sample output for the given program with one call to inc_num_kids():

Answers

Answer 1

Answer:

This is the instance method inc_num_kids()

def inc_num_kids(self):

       self.num_kids += 1

Explanation:

The first line is the definition of function inc_num_kids() which has a parameter self. self is basically an instance of  class PersonInfo

self.num_kids += 1 this statement incremented the data member num_kids by 1. This means that the instance method inc_num_kids, using instance self, increments the value of num_kids data member by 1.

The complete program is as following:

class PersonInfo:  #class name PersonInfo

   def __init__(self):   #constructor of the class

       self.num_kids = 0  # data member num_kids

   def inc_num_kids(self):  # method inc_num_kids

       self.num_kids += 1  #increments num_kids by 1

person1 = PersonInfo()  #creates object person of class PersonInfo

print('Kids:', person1.num_kids)  # prints num_kids value before increment

person1.inc_num_kids()  #calls inc_num_kids method to increment num_kids

print('New baby, kids now:', person1.num_kids) #prints the value of num_kids after increment by inc_num_kids method

The person1 object first access the initial value of num_kids initialized by the constructor. So the first value of num_kids is 0. self.num_kids = 0  This statement assigns the value 0 to num_kids data member. Next the method inc_num_kids() using the object person1. Now when this method is called the value of data member num_kids is incremented to 1.

So previously the value was 0 which now increments by 1 and becomes 1. Last print statement displays this new value which is incremented by the inc_num_kids() method.

Hence the output is:

Kids: 0

New baby, kids now: 1

The program along with its output is attached.

QUESTION 6 Which of the following is a class A IPv4 address? a. 118.20.210.254 b. 183.16.17.30 c. 215.16.17.30 d. 255.255.0.0

Answers

Answer:

a. 118.20.210.254

Explanation:

Here are the few characteristics of Class A:

First bit of the first octet of class A is 0.

This class has 8 bits for network and 24 bits for hosts.

The default sub-net mask for class A IP address is 255.0.0.0

Lets see if the first bit of first octet of 118.20.210.254 address is 0.

118 in binary (8 bits) can be represented as : 1110110

To complete 8 bits add a 0 to the left.

01110110

First bit of the first octet of class A is 0 So this is class A address.

For option b the first octet is : 183 in the form of bits = 10110111 So it is not class A address

For option c the first octet is 215 in the form of bits = 11010111 So it is not class A address

For option d the first octet is 255 in the form of bits = 11111111. The first bit of first octet is not 0 so it is also not class A address.

Write a function named twoWordsV2 that has the same specification as Problem 1, but implement it using while and not using break. (Hint: provide a different boolean condition for while.) Since only the implementation has changed, and not the specification, for a given input the output should be identical to the output in Problem 1.

Answers

Answer:

I am writing a Python program. Here is the function twoWordsV2:

def twoWordsV2 (length,firstLetter):#definition of function which takes length of the first word and first letter of the second word as parameter and returns these two words in a list

   word1 = "" # stores the first word

   word2= "" #holds the second word  

   while(len(word1)!=length): # checks if the input word1 length is not equal to the specified length

       word1 = input('A ' + str(length) + '-letter word please: ') #asks user to enter the input word1 of specified length

   while(word2!=firstLetter): #checks if the first character of input word2 is not equal to the specified firstLetter character

       word2 = input('A word beginning with ' + firstLetter+ ' please: ')#asks user to enter the input word2 begining with specified first letter

       if word2[0] == firstLetter.upper() or word2[0] == firstLetter.lower():#second word may begin with either an upper or lower case instance of firstLetter      

           return [word1,word2] #return the two words in a list                

   

#to check the working of the function use the following statement        

print(twoWordsV2(4,'B')) #calls twoWordsV2  method by passing 4 (length) and B (first letter)

Explanation:  

twoWordsV2 method has two parameters i.e length which is the length of the first word and firstLetter which is the first character of the the second word. This means the first word should be of specified length, and the second word should begin with a specified first letter. The function returns the two resultant words with the above specifications. These two words are displayed in a list. I will explain the working of the function with the help of an example:

Suppose length = 4 and firstLetter = 'B' and user enters "ok" as word1. input() method takes first word input from user.

The first while loop checks if the length of word1 i.e. ok is not equal to specified length i.e. 4. Length of word1 is checked using len function which returns 2 so length of word1 is 2. The loop condition is true because length of word1 i.e. 2 is not equal to specified length i.e. 4. So the body of the loop executes which displays this message:

A 4-letter word please:

Here notice that str(length) is changed to 4. This is because length=4 and str() converts this value into string.

So the above message keeps displaying until user enters a four letter word. Lets suppose user now enters "four". Now the while loop condition evaluates to false and the loop breaks. The program control  moves to the next line which is a while loop.

The second while loop checks if the first character of input word2 is not equal to the specified firstLetter character. Suppose word2 = "apple" and firstLetter= 'B'

Now the loop condition evaluates to true because word2 is not equal to first letter B. Now the main part of this while loop is the if condition: if word2[0] == firstLetter.upper() or word2[0] == firstLetter.lower() This statement checks if the first index of the word2 is equal to firstLetter. The word2 can contain a capital B or a small B so if condition checks both the cases by using upper and lower methods that converts the firstLetter to upper or lower and then match with the first letter of word2 i.e. the letter at index 0 of the word2. If this condition evaluates to true then next return statement returns the word1 and word2 in a list otherwise the second while loop keep asking user to enter the word2 with starting letter to be firstLetter i.e. 'B'.

The screenshot of the program and its output is attached.

The function for the given problem is:

def twoWordsV2 (length,firstLetter):word1 = "" # stores the first wordword2= "" #holds the second word   while(len(word1)!=length): word1 = input('A ' + str(length) + '-letter word please: ') while(word2!=firstLetter): word2 = input('A word beginning with ' + firstLetter+ ' please: ')if word2[0] == firstLetter.upper() or word2[0] == firstLetter.lower():    return [word1,word2]     print(twoWordsV2(4,'B')) Brief Explanation:

What is displayed in the alert dialog box after the following code is executed? var scores = [70, 20, 35, 15]; scores[scores.length] = 40; alert("The scores array: " + scores);

Answers

Answer:

The scores array: 70,20,35,15,40

Explanation:

I will explain the code line by line:

var scores = [70, 20, 35, 15];  

The above statement declares and assigns values to an array named scores

scores[scores.length] = 40;  

The above statement uses length to set the length of the scores array. It sets the last element of the scores array to 40. So this means 40 is set as the last element of scores.

scores.length returns the length of the scores array i.e. 4 as there are 4 elements in scores array 70,20,35,15

So the statement becomes:

scores[4] = 40;

This assigns value 40 to the 4th index of the scores array. Do not confuse 4th index with 4th element of the array because array element location starts from 0. So scores[4] does not mean 4th element but scores[4] means 4th index position of scores array. This makes 5th element of scores. So set the element 40 as 5th element at 4th index of scores.

alert("The scores array: " + scores);

This displays an alert box with the following message:

The scores array: 70,20,35,15,40

A continuous-time periodic signal x(t) is real valued and has a fundamental period T = 8. The nonzero Fourier series coefficients for x(t) are specified as
a_1 = a*_-1 = j, a_5 = a_-5 = 2.
Express x(t) in the form
x(t) = sigma^infinity_k=0 A_k cos(W_k t + phi_k).

Answers

Answer:

x(t) = −2 cos ( [tex]\frac{\pi }{4}t[/tex]  − [tex]\frac{\pi }{2}[/tex] ) + 4 cos ( [tex]\frac{5\pi }{4}t[/tex] )

Explanation:

Given:

Fundamental period of real valued continuous-time periodic signal x(t) = T = 8

Non-zero Fourier series coefficients for x(t) :

a₁ = [tex]a^{*}_{-1}[/tex] = j

a₅ = [tex]a_{-5}[/tex] = 2  

To find:

Express x(t) in the form

               ∞

x(t) =        ∑    A[tex]_{k}[/tex] cos ( w[tex]_{k}[/tex] t + φ[tex]_{k}[/tex] )

              [tex]_{k=0}[/tex]  

Solution:

Compute fundamental frequency of the signal:

w₀ = 2 π / T

     = 2 π / 8               Since T = 8

w₀  = π / 4

                   ∞

                    ∑ [tex]a_{k}e^{jw_{0}t }[/tex]

x(t) =          k=⁻∞

   

     =  [tex]a_{1}e^{jw_{0} t} + a_{-1}e^{-jw_{0} t} + a_{5}e^{5jw_{0} t}+a_{-5}e^{-5jw_{0} t}[/tex]  

     =  [tex]je^{j(\pi/4)t} - je^{-j(\pi/4)t} +2e^{(5\pi/4)t}+2e^{-(5\pi/4) t}[/tex]

     = −2 sin ( [tex]\frac{\pi }{4}t[/tex] ) + 4 cos ( [tex]\frac{5\pi }{4}t[/tex] )

     = −2 cos ( [tex]\frac{\pi }{4}t[/tex]  − [tex]\frac{\pi }{2}[/tex] ) + 4 cos ( [tex]\frac{5\pi }{4}t[/tex] )

What can you set to make sure that your client machines and the server times are in sync

Answers

Complete Question:

Let's say that you handle the IT systems administration for your company. There's a server inside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync?

Answer:

Network Time Protocol (NTP).

Explanation:

As the IT systems administrator, you can set the network time protocol (NTP) to make sure that your client machines and the server times are in synchronization.

A network time protocol (NTP) can be defined as an internet standard protocol which is used by an IT system administrator to synchronize a computer's clock to a particular time reference over packet switched or local area network (LAN) and variable-latency data networks. NTP was developed at the University of Delaware by Professor David L. Mills.

Basically, the network time protocol uses the coordinated universal time (UTC) and a client-server model to measure the total round-trip delay for a computer process.

What will be displayed after code corresponding to the following pseudocode is run? Main Set OldPrice = 100 Set SalePrice = 70 Call BigSale(OldPrice, SalePrice) Write "A jacket that originally costs $ " + OldPrice Write "is on sale today for $ " + SalePrice End Program Subprogram BigSale(Cost, Sale As Ref) Set Sale = Cost * .80 Set Cost = Cost + 20 End Subprogram

Answers

Answer:

A jacket that originally costs $ 100 is on sale today for $ 80                                    

Explanation:

Main : From here the execution of the program begins

Set OldPrice = 100  -> This line assigns 100 to the OldPrice variable

Set SalePrice = 70   -> This line assigns 70to the SalePrice variable

Call BigSale(OldPrice, SalePrice)  -> This line calls BigSale method by passing OldPrice and SalePrice to that method

Write "A jacket that originally costs $ ", OldPrice  -> This line prints/displays the line: "A jacket that originally costs $ " with the resultant value in OldPrice variable that is 100

Write "is on sale today for $ ", SalePrice  -> This line prints/displays the line: "is on sale today for $ " with the resultant value in SalePrice variable that is 80

End Program -> the main program ends

Subprogram BigSale(Cost, Sale As Ref)  -> this is a definition of BigSale method which has two parameters i.e. Cost and Sale. Note that the Sale is declared as reference type

Set Sale = Cost * .80  -> This line multiplies the value of Cost with 0.80 and assigns the result to Sale variable

Set Cost = Cost + 20  -> This line adds 20 to the value of Cost  and assigns the result to Cost variable

End Subprogram  -> the method ends

This is the example of call by reference. So when the method BigSale is called in Main by reference by passing argument SalePrice to it, then this call copies the reference of SalePrice argument into formal parameter Sale. Inside BigSale method the reference &Sale is used to access actual argument i.e. SalePrice which is used in BigSale(OldPrice, SalePrice) call. So any changes made to value of Sale will affect the value of SalePrice

So when the method BigSale is called two arguments are passed to it OldPrice argument and SalePrice is passed by reference.

The value of OldPrice is 100 and SalePrice is 70

Now when method BigSale is called, the reference &Sale is used to access actual argument SalePrice = 70

In the body of this method there are two statements:

Sale = Cost * .80;

Cost = Cost + 20;

So when these statement execute:

Sale = 100 * 0.80 = 80

Cost = 100 + 20 = 120

Any changes made to value of Sale will affect the value of SalePrice as it is passed by reference. So when the Write "A jacket that originally costs $ " + OldPrice Write "is on sale today for $ " + SalePrice statement executes, the value of OldPrice remains 100 same as it does not affect this passed argument, but SalePrice was passed by reference so the changes made to &Sale by statement in method BigSale i.e.  Sale = Cost * .80; has changed the value of SalePrice from 70 to 80 because Sale = 100 * 0.80 = 80. So the output produced is:

A jacket that originally costs $ 100 is on sale today for $ 80

Explanation:

The program is elaborated in the comments with each statement of the above code. The program has a class Plane that has a method CheckIn to handle the check in process. The user is prompted to enter a choice i.e. enter 1 to select First Class Seat and enter 2 to select Economy Seat. A switch statement is used to handle this process. If user enters 1 then the case 1 of switch statement executes which reserves a seat for the user in first class. If user enters 2 then the case 2 of switch statement executes which reserves a seat for the user in economy class.There are only 5 seats for each First Class and Economy.

Complete the below method, isPalindrome(), that takes in a String and returns a boolean. The boolean should be true if the String is a palindrome, i.e., the String is the same if read forwards or in reverse. For example, "racecar" is a palindrome. The method should return false if the String is not a palindrome. Note: any single-letter word is considered a palindrome.

public class StringMethod {
public static boolean isPalindrome(String word) {
//TODO: Complete this method

}
}

Answers

Answer:

public static boolean isPalindrome(String word) {

   //TODO: Complete this method

   String reverse = "";  

       for (int i = (word.length()-1); i>=0; i--) {

           if(word.charAt(i)!=' '){

               reverse+=word.charAt(i);

           }

       }

   String without_space = word.replaceAll(" ", "");

   

   return reverse.equals(without_space);

   }

Methods are collections of named code blocks, that are executed when called or evoked.

The isPalindrome method written in Java, where comments are used to explain each line is as follows

//This defines the method

public static boolean isPalindrome(String word) {

   //This removes all the spaces in the word

   String newStr = word.replaceAll(" ", "");

   //This initializes an empty string

   String rev = "";  

   //This iterates through the word, in reverse order

   for (int i = (word.length()-1); i>=0; i--) {

       //This gets all the characters in the string (without the space)

       if(word.charAt(i)!=' '){

           rev+=word.charAt(i);

       }

   }

   //This returns true or false

   return reverse.equals(newStr);

Assuming a Stop-and-Wait system, if the bandwidth-delay product of a channel is 500 Mbps and 1 bit takes 25 milliseconds to make the roundtrip, what is the bandwidth-delay product? If the data packets are 2500 bits in length, what is the utilization?

Answers

Answer:

Bandwidth delay product = 2500 Kbits

Utilization = 0.02%

Explanation:

We proceed as follows;

From the question, we are given that

band width = 500 Mbps

The bandwidth-delay product is = 500 x 10^6 x 25 x 10^-3

= 2500 Kbits

The system can send 12500 Kbits during the time it takes for the data to go from the sender to the receiver and then back again.

However, the system sends only 2500 bits.

The the link utilization =

2500/(12500 x 10^3) = 0.02%

Complete Question:

Jason has a part time job in the office of a construction company and is also a student at a community college. He often works on his homework during times when he is not busy at work because the office computer contains the software he needs to do his assignments and he hasn't been able to afford to purchase the software for his own personal computer. Which of these unacceptable uses typically included in a user access policy might he most likely be engaging in?

1.Using the network to download software for personal use

2.Disclosing personal information about employees

3.Copying of copyrighted material

4.Using a network account for a purpose not specified by the owner’s job description

Answer:

4.Using a network account for a purpose not specified by the owner’s job description

Explanation:

The office computer is meant to be used for the owner's purpose only.  By using the office computer to do his homework, even at a free hour, Jason is still violating his employer's asset for selfish purpose.  Jason could obtain permission from his manager to use the office computer for his homework for a temporary period, until he could "afford to purchase the software for his own personal computer."  The official permission can exempt him from being penalized for the violation.  A written permission is more ideal in this case.

Imagine you have a 10-character string stored in the variable myString. You want to pull out the first five characters. Which of the following lines of code would successfully generate a slice of the 10-character string holding only the first five characters?

a. myString[5]
b. myString[:-5]
c. myString[0:6]
d. myString-15:-5]
e. myString[0:10:2]

Answers

Answer:

b. myString[:-5]

d. myString[-15:-5]

Explanation:

I believe you have a typo in d. It must be d. myString[-15:-5]

Slicing can be done:

myString[starting_index, stopping_index, step] (step is optional). If you do not specify the starting index, it will start from the 0 as in b. If you write a range that is not in the range, as in d, Python will replace it with either 0 or length of the string (In this case, it is replaced with 0 because the starting index must be smaller than stopping index)

a. myString[5] → This will give you the sixth character

b. myString[:-5] → This will give you the first five characters

c. myString[0:6] → This will give you the first six characters

d. myString-15:-5] → This will give you the first five characters

e. myString[0:10:2] → This will give you the first, third, fifth, seventh, and ninth characters

A security administrator is investigating a report that a user is receiving suspicious emails. The user's machine has an old functioning modem installed. Which of the following security concerns need to be identified and mitigated? (Select TWO).
a) Vishing
b) Whaling
c) Spear phishing
d) Pharming
e) War dialing
f) Hoaxing

Answers

Answer:

Spear Phishing and War Dialing

Explanation:

So let's tackle these one at a time.

Vishing is simply any type of message (i.e., email, text, phone call, etc.) that appears to be from a trusted source but is not.

Whaling is simply a spear phishing attack of a high-value target such as a CEO or someone with high-level access at a company.

Spear phishing is simply a targeted phishing attack, usually towards a specific person or group of people.  (Phishing attack is simply a social attack to try and gain unauthorized access to a resource).

Pharming is an attack that attempts to redirect website traffic to a fake site.

War dialing is a technique to automatically scan a list of numbers in an area in attempt to search for exposed modems, computers, board systems, or fax machines, in order to breach the network.

Hoaxing is simply a social attack that describes a serious threat in attempts to retrieve unauthorized access or money from a victim.  (Think microsoft tech support scams)

Now that we have defined these things, let's identify the possible threats that need to be reported.

(a) Vishing?  The sec admin report doesn't mention the source of the message so we cannot associate this one

(b) Whaling? The sec admin report says a user, implying someone not high up in the company, but doesn't say it's not someone high up.  This is possible.

(c) Spear phishing?  The sec admin report says a user, implying that only this user is being targeted so this is definitely valid.

(d) Pharming?  The sec admin report says nothing about site redirection.

(e) War dialing? The sec admin report doesn't say anything about unauthorized scanning; however, it mentions the user has an old functioning modem, so this is possible.

(f) Hoaxing?  The sec admin report doesn't mention a pop up in the email or the content of the email so we are uncertain.

Thus with these considerations, the two threats that are identified and need mitigation are Spear phishing and War Dialing/Whaling.  Note that we aren't positive of the war dialing or whaling, but a case could be made for either; however, given the modem information, the question seems to indicate war dialing.
