Max value that can be expressed is 2¹⁶-1 = 65535

Answer:

(a) The user will be prompted to enter a different name

Explanation:

Given code;

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

var name = prompt("Enter the name to print on your tee-shirt");

while (name.length > 12) {

name = prompt("Too long. Enter a name with fewer than 12 characters.");

}

alert("The name to be printed is " + name.toUpperCase());

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

=>The first line of the code prompts the user to enter some name to be printed on their tee-shirt, and the input from the user is saved in a variable called name.

=> In the while block, the name variable is checked. If the length of the value of the variable is greater than 12 then a new prompt that says "Too long. Enter a name with fewer than 12 characters" is displayed.

=> In the last line, if the name variable is checked and the length is less than 12, then an alert statement showing the name in uppercase is displayed with some prepended texts.

Now, if the user enters Willy Shakespeare at the first prompt, the while block will be executed since Willy Shakespeare has over 12 characters.

In other words, the prompt in the while block, asking the user to enter a different name will be displayed. i.e

"Too long. Enter a name with fewer than 12 characters"

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.

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.

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

Answer:

I am writing a Python program.

def concordance(filename):  # function that takes a file name as parameter and returns the concordance for that file

   file = open(filename,"r")  #opens file in read mode

   unique={}  #creates and empty list

   for word in file.read().split():  #loops through every word in the file

       if word in unique:  # if words is already present in the list

           unique[word] += 1  #add 1 to the count of the existing word

       else:    #if word is not present in the list

           unique[word] = 1 #add the word to the list and add 1 to the count of word

           file.close();  # close the file

   for x in sorted(unique):  #sort the list and displays words with frequencies

       print(x, unique[x]);  #prints the unique words and their frequencies in alphabetical order

#prompts user to enter the name of the file

file_name=input('Enter the input file name: ')

concordance(file_name)  #calls concordance method by passing file name to it

Explanation:

The program has a function concordance that takes a text file name as parameter and returns a list of unique words and their frequencies.

The program first uses open() method to open the file in read mode. Here "r" represents the mode. Then creates an empty list named unique. Then the for loop iterates through each word in the file. Here the method read() is used to read the contents of file and split() is used to return these contents as a list of strings. The if condition inside the loop body checks each word if it is already present in the list unique. If the word is present then it adds 1 to the count of that word and if the word is not already present then it adds that unique word to the list and assign 1 as a count to that word. close() method then closes the file. The second for loop for x in sorted(unique):  is used to display the list of unique words with their frequencies. sorted() method is used to sort the list and then the loop iterates through each word in the list, through x, which acts like an index variable, and the loop displays each word along with its frequency.

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

A function is defined before it is first invoked.

Explanation:

A function prototype is a term in computer programming that is used as the declaration of a function that specifies function's name, parameters and return type. However, unlike function itself, which specifies what it does, a function prototype specifies function's interface only and not what it does.

Hence, A function prototype can always be omitted when: a function is defined before it is first invoked.

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%

Answer:

The correct form of the program in python is as follows

def even_numbers(maximum):

     return_string = ""  

     for x in range(1,maximum+1):

           if x % 2 == 0:

                 return_string+=str(x)+" "

     return return_string.strip()

Explanation:

This line defines the method

def even_numbers(maximum):

This line initializes return_string to an empty string

     return_string = ""  

This line iterates through variable maximum

     for x in range(1,maximum+1):

This line checks if the current number is even

           if x % 2 == 0:

If yes, the string is updated

                 return_string+=str(x)+" "

This line returns the full string of even numbers

    return return_string.strip()

When the method is tested with any of the following, it gives the desired result

print(even_numbers(6)), print(even_numbers(10)), print(even_numbers(1)), print(even_numbers(3)) and print(even_numbers(0))

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] )

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

cout<<"**************************"<<endl;

while(true){  // while loop executes the check in procedure

plane.CheckIn();} }  //class CheckIn method of Plane classs using plane object to start with the check in process

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. So when the limit of the seats reservation exceeds 5 then the no more seats available for you selection is displayed. If all the seats are taken in both the first and economy class then it displays the message All seats are reserved. If the user enters anything other than 1 or 2 then display the message Enter a valid choice. Whenever the user reserves one of first or economy class seats the relevant seat is incremented to 1 in order to count the number of seats being reserved. The program and its output are attached.

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.

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'.
